+/*!
+    \class QAction qaction.h
+    \brief The QAction class provides an abstract user interface
+    action that can appear both in menus and tool bars.
+
+    \ingroup basic
+    \ingroup application
+    \mainclass
+
+    In GUI applications many commands can be invoked via a menu
+    option, a toolbar button and a keyboard accelerator. Since the
+    same action must be performed regardless of how the action was
+    invoked, and since the menu and toolbar should be kept in sync, it
+    is useful to represent a command as an \e action. An action can be
+    added to a menu and a toolbar and will automatically keep them in
+    sync. For example, if the user presses a Bold toolbar button the
+    Bold menu item will automatically be checked.
+
+    A QAction may contain an icon, a menu text, an accelerator, a
+    status text, a whats this text and a tool tip. Most of these can
+    be set in the constructor. They can also be set independently with
+    setIconSet(), setText(), setMenuText(), setToolTip(),
+    setStatusTip(), setWhatsThis() and setAccel().
+
+    An action may be a toggle action e.g. a Bold toolbar button, or a
+    command action, e.g. 'Open File' to invoke an open file dialog.
+    Toggle actions emit the toggled() signal when their state changes.
+    Both command and toggle actions emit the activated() signal when
+    they are invoked. Use setToggleAction() to set an action's toggled
+    status. To see if an action is a toggle action use
+    isToggleAction(). A toggle action may be "on", isOn() returns
+    TRUE, or "off", isOn() returns FALSE.
+
+    Actions are added to widgets (menus or toolbars) using addTo(),
+    and removed using removeFrom().
+
+    Once a QAction has been created it should be added to the relevant
+    menu and toolbar and then connected to the slot which will perform
+    the action. For example:
+
+    \quotefile action/application.cpp
+    \skipto QPixmap( fileopen
+    \printuntil connect
+
+    We create a "File Save" action with a menu text of "&Save" and
+    \e{Ctrl+S} as the keyboard accelerator. We connect the
+    fileSaveAction's activated() signal to our own save() slot. Note
+    that at this point there is no menu or toolbar action, we'll add
+    them next:
+
+    \skipto new QToolBar
+    \printline
+    \skipto fileSaveAction->addTo
+    \printline
+    \skipto new QPopupMenu
+    \printuntil insertItem
+    \skipto fileSaveAction->addTo
+    \printline
+
+    We create a toolbar and add our fileSaveAction to it. Similarly we
+    create a menu, add a top-level menu item, and add our
+    fileSaveAction.
+
+    We recommend that actions are created as children of the window
+    that they are used in. In most cases actions will be children of
+    the application's main window.
+
+    To prevent recursion, don't create an action as a child of a
+    widget that the action is later added to.

+    \class QActionGroup qaction.h
+    \brief The QActionGroup class groups actions together.
+
+    \ingroup basic
+    \ingroup application
+
+    In some situations it is useful to group actions together. For
+    example, if you have a left justify action, a right justify action
+    and a center action, only one of these actions should be active at
+    any one time, and one simple way of achieving this is to group the
+    actions together in an action group.
+
+    An action group can also be added to a menu or a toolbar as a
+    single unit, with all the actions within the action group
+    appearing as separate menu options and toolbar buttons.
+
+    Here's an example from examples/textedit:
+    \quotefile textedit/textedit.cpp
+    \skipto QActionGroup
+    \printuntil connect
+
+    Here we create a new action group. Since the action group is exclusive
+    by default, only one of the actions in the group is ever active at any
+    one time. We then connect the group's selected() signal to our
+    textAlign() slot.
+
+    \printuntil actionAlignLeft->setToggleAction
+
+    We create a left align action, add it to the toolbar and the menu
+    and make it a toggle action. We create center and right align

+    A QActionGroup emits an activated() signal when one of its actions
+    is activated.
+    \endomit
+    The actions in an action group emit their activated() (and for
+    toggle actions, toggled()) signals as usual.
+
+    The setExclusive() function is used to ensure that only one action
+    is active at any one time: it should be used with actions which
+    have their \c toggleAction set to TRUE.
+
+    Action group actions appear as individual menu options and toolbar
+    buttons. For exclusive action groups use setUsesDropDown() to
+    display the actions in a subwidget of any widget the action group
+    is added to. For example, the actions would appear in a combobox
+    in a toolbar or as a submenu in a menu.
+
+    Actions can be added to an action group using add(), but normally
+    they are added by creating the action with the action group as
+    parent. Actions can have separators dividing them using
+    addSeparator(). Action groups are added to widgets with addTo().

+    \class QButton qbutton.h
+    \brief The QButton class is the abstract base class of button
+    widgets, providing functionality common to buttons.
+
+    \ingroup abstractwidgets
+
+    <b>If you want to create a button use QPushButton.</b>
+
+    The QButton class implements an \e abstract button, and lets
+    subclasses specify how to reply to user actions and how to draw
+    the button.
+
+    QButton provides both push and toggle buttons. The QRadioButton
+    and QCheckBox classes provide only toggle buttons; QPushButton and
+    QToolButton provide both toggle and push buttons.
+
+    Any button can have either a text or pixmap label. setText() sets
+    the button to be a text button and setPixmap() sets it to be a
+    pixmap button. The text/pixmap is manipulated as necessary to
+    create the "disabled" appearance when the button is disabled.
+
+    QButton provides most of the states used for buttons:
+    \list
+    \i isDown() indicates whether the button is \e pressed down.
+    \i isOn() indicates whether the button is \e on.
+       Only toggle buttons can be switched on and off  (see below).
+    \i isEnabled() indicates whether the button can be pressed by the
+       user.
+    \i setAutoRepeat() sets whether the button will auto-repeat
+       if the user holds it down.
+    \i setToggleButton() sets whether the button is a toggle
+       button or not.
+    \endlist
+
+    The difference between isDown() and isOn() is as follows: When the
+    user clicks a toggle button to toggle it on, the button is first
+    \e pressed and then released into the \e on state. When the user
+    clicks it again (to toggle it off), the button moves first to the
+    \e pressed state, then to the \e off state (isOn() and isDown()
+    are both FALSE).
+
+    Default buttons (as used in many dialogs) are provided by
+    QPushButton::setDefault() and QPushButton::setAutoDefault().
+
+    QButton provides five signals:
+    \list 1
+    \i pressed() is emitted when the button is pressed. E.g. with the mouse
+       or when animateClick() is called.
+    \i released() is emitted when the button is released. E.g. when the mouse
+       is released or the cursor is moved outside the widget.
+    \i clicked() is emitted when the button is first pressed and then
+       released when the accelerator key is typed, or when
+       animateClick() is called.
+    \i toggled(bool) is emitted when the state of a toggle button changes.
+    \i stateChanged(int) is emitted when the state of a tristate
+       toggle button changes.
+    \endlist
+
+    If the button is a text button with an ampersand (\&) in its text,
+    QButton creates an automatic accelerator key. This code creates a
+    push button labelled "Ro<u>c</u>k \& Roll" (where the c is
+    underlined). The button gets an automatic accelerator key, Alt+C:
+
+    \code
+	QPushButton *p = new QPushButton( "Ro&ck && Roll", this );
+    \endcode
+
+    In this example, when the user presses Alt+C the button will call
+    animateClick().
+
+    You can also set a custom accelerator using the setAccel()
+    function. This is useful mostly for pixmap buttons because they
+    have no automatic accelerator.
+
+    \code
+	p->setPixmap( QPixmap("print.png") );
+	p->setAccel( ALT+Key_F7 );
+    \endcode
+
+    All of the buttons provided by Qt (\l QPushButton, \l QToolButton,
+    \l QCheckBox and \l QRadioButton) can display both text and
+    pixmaps.
+
+    To subclass QButton, you must reimplement at least drawButton()
+    (to draw the button's outline) and drawButtonLabel() (to draw its
+    text or pixmap). It is generally advisable to reimplement
+    sizeHint() as well, and sometimes hitButton() (to determine
+    whether a button press is within the button).
+
+    To reduce flickering, QButton::paintEvent() sets up a pixmap that
+    the drawButton() function draws in. You should not reimplement
+    paintEvent() for a subclass of QButton unless you want to take
+    over all drawing.

+    \class QButtonGroup qbuttongroup.h
+    \brief The QButtonGroup widget organizes QButton widgets in a group.

+    \ingroup geomanagement
+    \ingroup appearance
+    \mainclass
+
+    A button group widget makes it easier to deal with groups of
+    buttons. Each button in a button group has a unique identifier.
+    The button group emits a clicked() signal with this identifier
+    when a button in the group is clicked. This makes a button group
+    particularly useful when you have several similar buttons and want
+    to connect all their clicked() signals to a single slot.
+
+    An \link setExclusive() exclusive\endlink button group switches
+    off all toggle buttons except the one that was clicked. A button
+    group is, by default, non-exclusive. Note that all radio buttons
+    that are inserted into a button group are mutually exclusive even
+    if the button group is non-exclusive. (See
+    setRadioButtonExclusive().)
+
+    There are two ways of using a button group:
+    \list
+    \i The button group is the parent widget of a number of buttons,
+    i.e. the button group is the parent argument in the button
+    constructor. The buttons are assigned identifiers 0, 1, 2, etc.,
+    in the order they are created. A QButtonGroup can display a frame
+    and a title because it inherits QGroupBox.
+    \i The button group is an invisible widget and the contained
+    buttons have some other parent widget. In this usage, each button
+    must be manually inserted, using insert(), into the button group
+    and given an identifier.
+    \endlist
+
+    A button can be removed from the group with remove(). A pointer to
+    a button with a given id can be obtained using find(). The id of a
+    button is available using id(). A button can be set \e on with
+    setButton(). The number of buttons in the group is returned by
+    count().

+    is equal to the number of buttons in the group. If \a id is any

+    \class QCheckBox qcheckbox.h
+    \brief The QCheckBox widget provides a checkbox with a text label.
+
+    \ingroup basic
+    \mainclass
+
+    QCheckBox and QRadioButton are both option buttons. That is, they
+    can be switched on (checked) or off (unchecked). The classes
+    differ in how the choices for the user are restricted. Radio
+    buttons define a "one of many" choice, whereas checkboxes provide
+    "many of many" choices.
+
+    A QButtonGroup can be used to group check buttons visually.
+
+    Whenever a checkbox is checked or cleared it emits the signal
+    toggled(). Connect to this signal if you want to trigger an action
+    each time the checkbox changes state. You can use isChecked() to
+    query whether or not a checkbox is checked.
+
+    \warning The toggled() signal can not be trusted for tristate
+    checkboxes.
+
+    In addition to the usual checked and unchecked states, QCheckBox
+    optionally provides a third state to indicate "no change". This
+    is useful whenever you need to give the user the option of neither
+    checking nor unchecking a checkbox. If you need this third state,
+    enable it with setTristate() and use state() to query the current
+    toggle state. When a tristate checkbox changes state, it emits the
+    stateChanged() signal.
+
+    Just like QPushButton, a checkbox can display text or a pixmap.
+    The text can be set in the constructor or with setText(); the
+    pixmap is set with setPixmap().

+    \class QComboBox qcombobox.h
+    \brief The QComboBox widget is a combined button and popup list.
+
+    \ingroup basic
+    \mainclass
+
+    A combobox is a selection widget which displays the current item
+    and can pop up a list of items. A combobox may be editable in
+    which case the user can enter arbitrary strings.
+
+    Comboboxes provide a means of showing the user's current choice
+    out of a list of options in a way that takes up the minimum amount
+    of screen space.
+
+    QComboBox supports three different display styles: Aqua/Motif 1.x,
+    Motif 2.0 and Windows. In Motif 1.x, a combobox was called
+    XmOptionMenu. In Motif 2.0, OSF introduced an improved combobox
+    and named that XmComboBox. QComboBox provides both.
+
+    QComboBox provides two different constructors. The simplest
+    constructor creates an "old-style" combobox in Motif (or Aqua)
+    style:
+    \code
+	QComboBox *c = new QComboBox( this, "read-only combobox" );
+    \endcode
+
+    The other constructor creates a new-style combobox in Motif style,
+    and can create both read-only and editable comboboxes:
+    \code
+	QComboBox *c1 = new QComboBox( FALSE, this, "read-only combobox" );
+	QComboBox *c2 = new QComboBox( TRUE, this, "editable combobox" );
+    \endcode
+
+    New-style comboboxes use a list box in both Motif and Windows
+    styles, and both the content size and the on-screen size of the
+    list box can be limited with sizeLimit() and setMaxCount()
+    respectively. Old-style comboboxes use a popup in Aqua and Motif
+    style, and that popup will happily grow larger than the desktop if
+    you put enough data into it.
+
+    The two constructors create identical-looking comboboxes in
+    Windows style.
+
+    Comboboxes can contain pixmaps as well as strings; the
+    insertItem() and changeItem() functions are suitably overloaded.
+    For editable comboboxes, the function clearEdit() is provided,
+    to clear the displayed string without changing the combobox's
+    contents.
+
+    A combobox emits two signals, activated() and highlighted(), when
+    a new item has been activated (selected) or highlighted (made
+    current). Both signals exist in two versions, one with a \c
+    QString argument and one with an \c int argument. If the user
+    highlights or activates a pixmap, only the \c int signals are
+    emitted. Whenever the text of an editable combobox is changed the
+    textChanged() signal is emitted.
+
+    When the user enters a new string in an editable combobox, the
+    widget may or may not insert it, and it can insert it in several
+    locations. The default policy is is \c AtBottom but you can change
+    this using setInsertionPolicy().
+
+    It is possible to constrain the input to an editable combobox
+    using QValidator; see setValidator(). By default, any input is
+    accepted.
+
+    If the combobox is not editable then it has a default
+    focusPolicy() of \c TabFocus, i.e. it will not grab focus if
+    clicked. This differs from both Windows and Motif. If the combobox
+    is editable then it has a default focusPolicy() of \c StrongFocus,
+    i.e. it will grab focus if clicked.
+
+    A combobox can be populated using the insert functions,
+    insertStringList() and insertItem() for example. Items can be
+    changed with changeItem(). An item can be removed with
+    removeItem() and all items can be removed with clear(). The text
+    of the current item is returned by currentText(), and the text of
+    a numbered item is returned with text(). The current item can be
+    set with setCurrentItem() or setCurrentText(). The number of items
+    in the combobox is returned by count(); the maximum number of
+    items can be set with setMaxCount(). You can allow editing using
+    setEditable(). For editable comboboxes you can set auto-completion
+    using setAutoCompletion() and whether or not the user can add
+    duplicates is set with setDuplicatesEnabled().

+
+    Depending on the style, QComboBox will use a QListBox or a
+    QPopupMenu to display the list of items. See setListBox() for
+    more information.

+    \brief The QDateEdit class provides a date editor.

+    \ingroup advanced

+    \mainclass
+
+    QDateEdit allows the user to edit dates by using the keyboard or
+    the arrow keys to increase/decrease date values. The arrow keys
+    can be used to move from section to section within the QDateEdit
+    box. Dates appear in accordance with the local date/time settings
+    or in year, month, day order if the system doesn't provide this
+    information. It is recommended that the QDateEdit be initialised
+    with a date, e.g.
+
+    \code
+    QDateEdit *dateEdit = new QDateEdit( QDate::currentDate(), this );
+    dateEdit->setRange( QDate::currentDate().addDays( -365 ),
+			QDate::currentDate().addDays(  365 ) );
+    dateEdit->setOrder( QDateEdit::MDY );
+    dateEdit->setAutoAdvance( TRUE );
+    \endcode
+
+    Here we've created a new QDateEdit object initialised with today's
+    date and restricted the valid date range to today plus or minus
+    365 days. We've set the order to month, day, year. If the auto
+    advance property is TRUE (as we've set it here) when the user
+    completes a section of the date, e.g. enters two digits for the
+    month, they are automatically taken to the next section.
+
+    The maximum and minimum values for a date value in the date editor
+    default to the maximum and minimum values for a QDate. You can
+    change this by calling setMinValue(), setMaxValue() or setRange().
+
+    Terminology: A QDateEdit widget comprises three 'sections', one
+    each for the year, month and day. You can change the separator
+    character using QDateTimeEditor::setSeparator(), by default the
+    separator will be taken from the systems settings. If that is
+    not possible, it defaults to "-".

+    \ingroup advanced

+    \mainclass
+
+    QTimeEdit allows the user to edit times by using the keyboard or
+    the arrow keys to increase/decrease time values. The arrow keys
+    can be used to move from section to section within the QTimeEdit
+    box. The user can automatically be moved to the next section once
+    they complete a section using setAutoAdvance(). Times appear in
+    hour, minute, second order. It is recommended that the QTimeEdit
+    is initialised with a time, e.g.
+    \code
+    QTime timeNow = QTime::currentTime();
+    QTimeEdit *timeEdit = new QTimeEdit( timeNow, this );
+    timeEdit->setRange( timeNow, timeNow.addSecs( 60 * 60 ) );
+    \endcode
+    Here we've created a QTimeEdit widget set to the current time.
+    We've also set the minimum value to the current time and the
+    maximum time to one hour from now.
+
+    The maximum and minimum values for a time value in the time editor
+    default to the maximum and minimum values for a QTime. You can
+    change this by calling setMinValue(), setMaxValue() or setRange().
+
+    Terminology: A QTimeWidget consists of three sections, one each
+    for the hour, minute and second. You can change the separator
+    character using setSeparator(), by default the separator is read
+    from the system's settings.

+    \brief The QDateTimeEdit class combines a QDateEdit and QTimeEdit
+    widget into a single widget for editing datetimes.
+
+    \ingroup advanced
+    \ingroup time
+    \mainclass
+
+    QDateTimeEdit consists of a QDateEdit and QTimeEdit widget placed
+    side by side and offers the functionality of both. The user can
+    edit the date and time by using the keyboard or the arrow keys to
+    increase/decrease date or time values. The Tab key can be used to
+    move from section to section within the QDateTimeEdit widget, and
+    the user can be moved automatically when they complete a section
+    using setAutoAdvance(). The datetime can be set with
+    setDateTime().
+
+    The date format is read from the system's locale settings. It is
+    set to year, month, day order if that is not possible. See
+    QDateEdit::setOrder() to change this. Times appear in the order
+    hours, minutes, seconds using the 24 hour clock.
+
+    It is recommended that the QDateTimeEdit is initialised with a
+    datetime, e.g.
+    \code
+    QDateTimeEdit *dateTimeEdit = new QDateTimeEdit( QDateTime::currentDateTime(), this );
+    dateTimeEdit->dateEdit()->setRange( QDateTime::currentDate(),
+					QDateTime::currentDate().addDays( 7 ) );
+    \endcode
+    Here we've created a new QDateTimeEdit set to the current date and
+    time, and set the date to have a minimum date of now and a maximum
+    date of a week from now.
+
+    Terminology: A QDateEdit widget consists of three 'sections', one
+    each for the year, month and day. Similarly a QTimeEdit consists
+    of three sections, one each for the hour, minute and second. The
+    character that separates each date section is specified with
+    setDateSeparator(); similarly setTimeSeparator() is used for the
+    time sections.

+/*!
+    \class QDial qdial.h
+
+    \brief The QDial class provides a rounded range control (like a speedometer or potentiometer).
+
+    \ingroup basic
+    \mainclass
+
+    QDial is used when the user needs to control a value within a
+    program-definable range, and the range either wraps around
+    (typically, 0..359 degrees) or the dialog layout needs a square
+    widget.
+
+    Both API- and UI-wise, the dial is very similar to a \link QSlider
+    slider. \endlink Indeed, when wrapping() is FALSE (the default)
+    there is no real difference between a slider and a dial. They
+    have the same signals, slots and member functions, all of which do
+    the same things. Which one you use depends only on your taste
+    and on the application.
+
+    The dial initially emits valueChanged() signals continuously while
+    the slider is being moved; you can make it emit the signal less
+    often by calling setTracking(FALSE). dialMoved() is emitted
+    continuously even when tracking() is FALSE.
+
+    The slider also emits dialPressed() and dialReleased() signals
+    when the mouse button is pressed and released. But note that the
+    dial's value can change without these signals being emitted; the
+    keyboard and wheel can be used to change the value.
+
+    Unlike the slider, QDial attempts to draw a "nice" number of
+    notches rather than one per lineStep(). If possible, the number
+    of notches drawn is one per lineStep(), but if there aren't enough
+    pixels to draw every one, QDial will draw every second, third
+    etc., notch. notchSize() returns the number of units per notch,
+    hopefully a multiple of lineStep(); setNotchTarget() sets the
+    target distance between neighbouring notches in pixels. The
+    default is 3.75 pixels.
+
+    Like the slider, the dial makes the QRangeControl functions
+    setValue(), addLine(), subtractLine(), addPage() and
+    subtractPage() available as slots.
+
+    The dial's keyboard interface is fairly simple: The left/up and
+    right/down arrow keys move by lineStep(), page up and page down by
+    pageStep() and Home and End to minValue() and maxValue().

+    \class QDockArea qdockarea.h
+    \brief The QDockArea class manages and lays out QDockWindows.
+
+    \ingroup application
+
+    A QDockArea is a container which manages a list of
+    \l{QDockWindow}s which it lays out within its area. In cooperation
+    with the \l{QDockWindow}s it is responsible for the docking and
+    undocking of \l{QDockWindow}s and moving them inside the dock
+    area. QDockAreas also handle the wrapping of \l{QDockWindow}s to
+    fill the available space as compactly as possible. QDockAreas can
+    contain QToolBars since QToolBar is a QDockWindow subclass.
+
+    QMainWindow contains four QDockAreas which you can use for your
+    QToolBars and QDockWindows, so in most situations you do not need
+    to use the QDockArea class directly. Although QMainWindow contains
+    support for its own dock areas it isn't convenient for adding new
+    QDockAreas. If you need to create your own dock areas we suggest
+    that you create a subclass of QWidget and add your QDockAreas to
+    your subclass.
+
+    \img qmainwindow-qdockareas.png QMainWindow's QDockAreas
+
+    \target lines
+    \e Lines. QDockArea uses the concept of lines. A line is a
+    horizontal region which may contain dock windows side-by-side. A
+    dock area may have room for more than one line. When dock windows
+    are docked into a dock area they are usually added at the right
+    hand side of the top-most line that has room (unless manually
+    placed by the user). When users move dock windows they may leave
+    empty lines or gaps in non-empty lines. Dock windows can be lined
+    up to minimize wasted space using the lineUp() function.
+
+    The QDockArea class maintains a position list of all its child
+    dock windows. Dock windows are added to a dock area from position
+    0 onwards. Dock windows are laid out sequentially in position
+    order from left to right, and in the case of multiple lines of
+    dock windows, from top to bottom. If a dock window is floated it
+    still retains its position since this is where the window will
+    return if the user double clicks its caption. A dock window's
+    position can be determined with hasDockWindow(). The position can
+    be changed with moveDockWindow().
+
+    To dock or undock a dock window use QDockWindow::dock() and
+    QDockWindow::undock() respectively. If you want to control which
+    dock windows can dock in a dock area use setAcceptDockWindow(). To
+    see if a dock area contains a particular dock window use
+    \l{hasDockWindow()}; to see how many dock windows a dock area
+    contains use count().
+
+    The streaming operators can write the positions of the dock
+    windows in the dock area to a QTextStream. The positions can be
+    read back later to restore the saved positions.
+
+    Save the positions to a QTextStream:
+    \code
+    ts << *myDockArea;
+    \endcode
+
+    Restore the positions from a QTextStream:
+    \code
+    ts >> *myDockArea;
+    \endcode

+    \class QDockWindow qdockwindow.h
+    \brief The QDockWindow class provides a widget which can be docked
+    inside a QDockArea or floated as a top level window on the
+    desktop.
+
+    \ingroup application
+    \mainclass
+
+    This class handles moving, resizing, docking and undocking dock
+    windows. QToolBar is a subclass of QDockWindow so the
+    functionality provided for dock windows is available with the same
+    API for toolbars.
+
+    \img qmainwindow-qdockareas.png QDockWindows in a QDockArea
+    \caption Two QDockWindows (\l{QToolBar}s) in a \l QDockArea
+
+    \img qdockwindow.png A QDockWindow
+    \caption A Floating QDockWindow
+
+    If the user drags the dock window into the dock area the dock
+    window will be docked. If the user drags the dock area outside any
+    dock areas the dock window will be undocked (floated) and will
+    become a top level window. Double clicking a floating dock
+    window's titlebar will dock the dock window to the last dock area
+    it was docked in. Double clicking a docked dock window's handle
+    will undock (float) the dock window.
+    \omit
+    Single clicking a docked dock window's handle will minimize the
+    dock window (only its handle will appear, below the menu bar).
+    Single clicking the minimized handle will restore the dock window
+    to the last dock area that it was docked in.
+    \endomit
+    If the user clicks the close button (which does not appear on
+    dock windows by default - see \l closeMode) the dock window will
+    disappear. You can control whether or not a dock window has a
+    close button with setCloseMode().
+
+    QMainWindow provides four dock areas (top, left, right and bottom)
+    which can be used by dock windows. For many applications using the
+    dock areas provided by QMainWindow is sufficient. (See the \l
+    QDockArea documentation if you want to create your own dock
+    areas.) In QMainWindow a right-click popup menu (the dock window
+    menu) is available which lists dock windows and can be used to
+    show or hide them. (The popup menu only lists dock windows that
+    have a \link setCaption() caption\endlink.)
+
+    When you construct a dock window you \e must pass it a QDockArea
+    or a QMainWindow as its parent if you want it docked. Pass 0 for
+    the parent if you want it floated.
+
+    \code
+    QToolBar *fileTools = new QToolBar( this, "File Actions" );
+    moveDockWindow( fileTools, Left );
+    \endcode
+
+    In the example above we create a new QToolBar in the constructor
+    of a QMainWindow subclass (so that the \e this pointer points to
+    the QMainWindow). By default the toolbar will be added to the \c
+    Top dock area, but we've moved it to the \c Left dock area.
+
+    A dock window is often used to contain a single widget. In these
+    cases the widget can be set by calling setWidget(). If you're
+    constructing a dock window that contains multiple widgets, e.g. a
+    toolbar, arrange the widgets within a box layout inside the dock
+    window. To do this use the boxLayout() function to get a pointer
+    to the dock window's box layout, then add widgets to the layout
+    using the box layout's QBoxLayout::addWidget() function. The dock
+    window will dynamically set the orientation of the layout to be
+    vertical or horizontal as necessary, although you can control this
+    yourself with setOrientation().
+
+    Although a common use of dock windows is for toolbars, they can be
+    used with any widgets. (See the \link designer-manual.book Qt
+    Designer\endlink and \link linguist-manual.book Qt
+    Linguist\endlink applications, for example.) When using larger
+    widgets it may make sense for the dock window to be resizable by
+    calling setResizeEnabled(). Resizable dock windows are given
+    splitter-like handles to allow the user to resize them within
+    their dock area. When resizable dock windows are undocked they
+    become top level windows and can be resized like any other top
+    level windows, e.g. by dragging a corner or edge.
+
+    Dock windows can be docked and undocked using dock() and undock().
+    A dock window's orientation can be set with setOrientation(). You
+    can also use QDockArea::moveDockWindow(). If you're using a
+    QMainWindow, QMainWindow::moveDockWindow() and
+    QMainWindow::removeDockWindow() are available.
+
+    A dock window can have some preferred settings, for example, you
+    can set a preferred offset from the left edge (or top edge for
+    vertical dock areas) of the dock area using setOffset(). If you'd
+    prefer a dock window to start on a new \link qdockarea.html#lines
+    line\endlink when it is docked use setNewLine(). The
+    setFixedExtentWidth() and setFixedExtentHeight() functions can be
+    used to define the dock window's preferred size, and the
+    setHorizontallyStretchable() and setVerticallyStretchable()
+    functions set whether the dock window can be stretched or not.
+    Dock windows can be moved by default, but this can be changed with
+    setMovingEnabled(). When a dock window is moved it is shown as a
+    rectangular outline, but it can be shown normally using
+    setOpaqueMoving().
+
+    When a dock window's visibility changes, i.e. it is shown or
+    hidden, the visibilityChanged() signal is emitted. When a dock
+    window is docked, undocked or moved inside the dock area the
+    placeChanged() signal is emitted.

+    \class QFrame
+    \brief The QFrame class is the base class of widgets that can have a frame.
+
+    \ingroup abstractwidgets
+
+    It draws a frame and calls a virtual function, drawContents(), to
+    fill in the frame. This function is reimplemented by subclasses.
+    There are also two other less useful functions: drawFrame() and
+    frameChanged().
+
+    QPopupMenu uses this to "raise" the menu above the surrounding
+    screen. QProgressBar has a "sunken" look. QLabel has a flat look.
+    The frames of widgets like these can be changed.
+
+    \code
+    QLabel label(...);
+    label.setFrameStyle( QFrame::Panel | QFrame::Raised );
+    label.setLineWidth( 2 );
+
+    QProgressBar pbar(...);
+    label.setFrameStyle( QFrame::NoFrame );
+    \endcode
+
+    The QFrame class can also be used directly for creating simple
+    frames without any contents, although usually you would use a
+    QHBox or QVBox because they automatically lay out the widgets you
+    put inside the frame.
+
+    A frame widget has four attributes: frameStyle(), lineWidth(),
+    midLineWidth(), and margin().
+
+    The frame style is specified by a \link QFrame::Shape frame
+    shape\endlink and a \link QFrame::Shadow shadow style\endlink. The
+    frame shapes are \c NoFrame, \c Box, \c Panel, \c StyledPanel, \c
+    PopupPanel, \c WinPanel, \c ToolBarPanel, \c MenuBarPanel, \c
+    HLine and \c VLine; the shadow styles are \c Plain, \c Raised and
+    \c Sunken.
+
+    The line width is the width of the frame border.
+
+    The mid-line width specifies the width of an extra line in the
+    middle of the frame, which uses a third color to obtain a special
+    3D effect. Notice that a mid-line is only drawn for \c Box, \c
+    HLine and \c VLine frames that are raised or sunken.
+
+    The margin is the gap between the frame and the contents of the
+    frame.
+
+    \target picture
+    This table shows the most useful combinations of styles and widths
+    (and some rather useless ones):

+    \value Panel  QFrame draws a panel to make the contents appear

+    \value StyledPanel  draws a rectangular panel with a look that
+    depends on the current GUI style. It can be raised or sunken.
+    \value HLine  QFrame draws a horizontal line that frames nothing
+    (useful as separator)
+    \value VLine  QFrame draws a vertical line that frames nothing
+    (useful as separator)
+    \value GroupBoxPanel draws a rectangular panel
+    \value WinPanel draws a rectangular panel that can be raised or
+    sunken like those in Windows 95. Specifying this shape sets
+    the line width to 2 pixels. WinPanel is provided for compatibility.
+    For GUI style independence we recommend using StyledPanel instead.
+    \value ToolBarPanel
+    \value MenuBarPanel
+    \value PopupPanel

+    \class QGridView qgridview.h
+    \brief The QGridView class provides an abstract base for
+    fixed-size grids.
+
+    \ingroup abstractwidgets
+
+    A grid view consists of a number of abstract cells organized in
+    rows and columns. The cells have a fixed size and are identified
+    with a row index and a column index. The top-left cell is in row
+    0, column 0. The bottom-right cell is in row numRows()-1, column
+    numCols()-1.
+
+    You can define \l numRows, \l numCols, \l cellWidth and \l
+    cellHeight. Reimplement the pure virtual function paintCell() to
+    draw the contents of a cell.
+
+    With ensureCellVisible(), you can ensure a certain cell is
+    visible. With rowAt() and columnAt() you can find a cell based on
+    the given x- and y-coordinates.
+
+    If you need to monitor changes to the grid's dimensions (i.e. when
+    numRows or numCols is changed), reimplement the dimensionChange()
+    change handler.
+
+    Note: the row and column indices are always given in the order,
+    row (vertical offset) then column (horizontal offset). This order
+    is the opposite of all pixel operations, which are given in the
+    order x (horizontal offset), y (vertical offset).
+
+    QGridView is a very simple abstract class based on QScrollView. It
+    is designed to simplify the task of drawing many cells of the same
+    size in a potentially scrollable canvas. If you need rows and
+    columns with different sizes, use a QTable instead. If you need a
+    simple list of items, use a QListBox. If you need to present
+    hierachical data use a QListView, and if you need random objects
+    at random positions, consider using either a QIconView or a
+    QCanvas.

+    \class QGroupBox qgroupbox.h
+    \brief The QGroupBox widget provides a group box frame with a title.
+
+    \ingroup organizers
+    \ingroup geomanagement
+    \ingroup appearance
+    \mainclass
+
+    A group box provides a frame, a title and a keyboard shortcut, and
+    displays various other widgets inside itself. The title is on top,
+    the keyboard shortcut moves keyboard focus to one of the group
+    box's child widgets, and the child widgets are usually laid out
+    horizontally (or vertically) inside the frame.
+
+    The simplest way to use it is to create a group box with the
+    desired number of columns (or rows) and orientation, and then just
+    create widgets with the group box as parent.
+
+    It is also possible to change the orientation() and number of
+    columns() after construction, or to ignore all the automatic
+    layout support and manage the layout yourself. You can add 'empty'
+    spaces to the group box with addSpace().
+
+    QGroupBox also lets you set the title() (normally set in the
+    constructor) and the title's alignment().
+
+    You can change the spacing used by the group box with
+    setInsideMargin() and setInsideSpacing(). To minimize space
+    consumption, you can remove the right, left and bottom edges of
+    the frame with setFlat().

+    \class QHeader qheader.h
+    \brief The QHeader class provides a header row or column, e.g. for
+    tables and listviews.
+
+    \ingroup advanced
+
+    This class provides a header, e.g. a vertical header to display
+    row labels, or a horizontal header to display column labels. It is
+    used by QTable and QListView for example.
+
+    A header is composed of one or more \e sections, each of which can
+    display a text label and an \link QIconSet iconset\endlink. A sort
+    indicator (an arrow) can also be displayed using
+    setSortIndicator().
+
+    Sections are added with addLabel() and removed with removeLabel().
+    The label and iconset are set in addLabel() and can be changed
+    later with setLabel(). Use count() to retrieve the number of
+    sections in the header.
+
+    The orientation of the header is set with setOrientation(). If
+    setStretchEnabled() is TRUE, the sections will expand to take up
+    the full width (height for vertical headers) of the header. The
+    user can resize the sections manually if setResizeEnabled() is
+    TRUE. Call adjustHeaderSize() to have the sections resize to
+    occupy the full width (or height).
+
+    A section can be moved with moveSection(). If setMovingEnabled()
+    is TRUE (the default)the user may drag a section from one position
+    to another. If a section is moved, the index positions at which
+    sections were added (with addLabel()), may not be the same after the
+    move. You don't have to worry about this in practice because the
+    QHeader API works in terms of section numbers, so it doesn't matter
+    where a particular section has been moved to.
+
+    If you want the current index position of a section call
+    mapToIndex() giving it the section number. (This is the number
+    returned by the addLabel() call which created the section.) If you
+    want to get the section number of a section at a particular index
+    position call mapToSection() giving it the index number.
+
+    Here's an example to clarify mapToSection() and mapToIndex():
+
+    \table
+    \header \i41 Index positions
+    \row \i 0 \i 1 \i 2 \i 3
+    \header \i41 Original section ordering
+    \row \i Sect 0 \i Sect 1 \i Sect 2 \i Sect 3
+    \header \i41 Ordering after the user moves a section
+    \row \i Sect 0 \i Sect 2 \i Sect 3 \i Sect 1
+    \endtable
+
+    \table
+    \header \i \e k \i mapToSection(\e k) \i mapToIndex(\e k)
+    \row \i 0 \i 0 \i 0
+    \row \i 1 \i 2 \i 3
+    \row \i 2 \i 3 \i 1
+    \row \i 3 \i 1 \i 2
+    \endtable
+
+    In the example above, if we wanted to find out which section is at
+    index position 3 we'd call mapToSection(3) and get a section
+    number of 1 since section 1 was moved. Similarly, if we wanted to
+    know which index position section 2 occupied we'd call
+    mapToIndex(2) and get an index of 1.
+
+    QHeader provides the clicked(), pressed() and released() signals.
+    If the user changes the size of a section, the sizeChange() signal
+    is emitted. If you want to have a sizeChange() signal emitted
+    continuously whilst the user is resizing (rather than just after
+    the resizing is finished), use setTracking(). If the user moves a
+    section the indexChange() signal is emitted.

+    \class QLabel qlabel.h
+    \brief The QLabel widget provides a text or image display.
+
+    \ingroup basic
+    \ingroup text
+    \mainclass
+
+    QLabel is used for displaying text or an image. No user
+    interaction functionality is provided. The visual appearance of
+    the label can be configured in various ways, and it can be used
+    for specifying a focus accelerator key for another widget.
+
+    A QLabel can contain any of the following content types:
+    \table
+    \header \i Content \i Setting
+    \row \i Plain text
+	 \i Pass a QString to setText().
+    \row \i Rich text
+	 \i Pass a QString that contains rich text to setText().
+    \row \i A pixmap
+	 \i Pass a QPixmap to setPixmap().
+    \row \i A movie
+	 \i Pass a QMovie to setMovie().
+    \row \i A number
+	 \i Pass an \e int or a \e double to setNum(), which converts
+	    the number to plain text.
+    \row \i Nothing
+	 \i The same as an empty plain text. This is the default. Set
+	    by clear().
+    \endtable
+
+    When the content is changed using any of these functions, any
+    previous content is cleared.
+
+    The look of a QLabel can be tuned in several ways. All the
+    settings of QFrame are available for specifying a widget frame.
+    The positioning of the content within the QLabel widget area can
+    be tuned with setAlignment() and setIndent(). For example, this
+    code sets up a sunken panel with a two-line text in the bottom
+    right corner (both lines being flush with the right side of the
+    label):
+    \code
+    QLabel *label = new QLabel( this );
+    label->setFrameStyle( QFrame::Panel | QFrame::Sunken );
+    label->setText( "first line\nsecond line" );
+    label->setAlignment( AlignBottom | AlignRight );
+    \endcode
+
+    A QLabel is often used as a label for an interactive widget. For
+    this use QLabel provides a useful mechanism for adding an
+    accelerator key (see QAccel) that will set the keyboard focus to
+    the other widget (called the QLabel's "buddy"). For example:
+    \code
+    QLineEdit* phoneEdit = new QLineEdit( this, "phoneEdit" );
+    QLabel* phoneLabel = new QLabel( phoneEdit, "&Phone:", this, "phoneLabel" );
+    \endcode
+
+    In this example, keyboard focus is transferred to the label's
+    buddy (the QLineEdit) when the user presses Alt+P. You can
+    also use the setBuddy() function to accomplish the same thing.

+    \class QLCDNumber qlcdnumber.h
+
+    \brief The QLCDNumber widget displays a number with LCD-like digits.
+
+    \ingroup basic
+    \mainclass
+
+    It can display a number in just about any size. It can display
+    decimal, hexadecimal, octal or binary numbers. It is easy to
+    connect to data sources using the display() slot, which is
+    overloaded to take any of five argument types.
+
+    There are also slots to change the base with setMode() and the
+    decimal point with setSmallDecimalPoint().
+
+    QLCDNumber emits the overflow() signal when it is asked to display
+    something beyond its range. The range is set by setNumDigits(),
+    but setSmallDecimalPoint() also influences it. If the display is
+    set to hexadecimal, octal or binary, the integer equivalent of the
+    value is displayed.
+
+    These digits and other symbols can be shown: 0/O, 1, 2, 3, 4, 5/S,
+    6, 7, 8, 9/g, minus, decimal point, A, B, C, D, E, F, h, H, L, o,
+    P, r, u, U, Y, colon, degree sign (which is specified as single
+    quote in the string) and space. QLCDNumber substitutes spaces for
+    illegal characters.
+
+    It is not possible to retrieve the contents of a QLCDNumber
+    object, although you can retrieve the numeric value with value().
+    If you really need the text, we recommend that you connect the
+    signals that feed the display() slot to another slot as well and
+    store the value there.
+
+    Incidentally, QLCDNumber is the very oldest part of Qt, tracing
+    back to a BASIC program on the \link
+    http://www.nvg.ntnu.no/sinclair/computers/zxspectrum/zxspectrum.htm

+    \class QLineEdit
+    \brief The QLineEdit widget is a one-line text editor.
+
+    \ingroup basic
+    \mainclass
+
+    A line edit allows the user to enter and edit a single line of
+    plain text with a useful collection of editing functions,
+    including undo and redo, cut and paste, and drag and drop.
+
+    By changing the echoMode() of a line edit, it can also be used as
+    a "write-only" field, for inputs such as passwords.
+
+    The length of the text can be constrained to maxLength(). The text
+    can be arbitrarily constrained using a validator() or an
+    inputMask(), or both.
+
+    A related class is QTextEdit which allows multi-line, rich-text
+    editing.
+
+    You can change the text with setText() or insert(). The text is
+    retrieved with text(); the displayed text (which may be different,
+    see \l{EchoMode}) is retrieved with displayText(). Text can be
+    selected with setSelection() or selectAll(), and the selection can
+    be cut(), copy()ied and paste()d. The text can be aligned with
+    setAlignment().
+
+    When the text changes the textChanged() signal is emitted; when
+    the Return or Enter key is pressed the returnPressed() signal is
+    emitted. Note that if there is a validator set on the line edit,
+    the returnPressed() signal will only be emitted if the validator
+    returns \c Acceptable.
+
+    By default, QLineEdits have a frame as specified by the Windows
+    and Motif style guides; you can turn it off by calling
+    setFrame(FALSE).
+
+    The default key bindings are described below. The line edit also
+    provides a context menu (usually invoked by a right mouse click)
+    that presents some of these editing options.
+    \target desc
+    \table
+    \header \i Keypress \i Action
+    \row \i Left Arrow \i Moves the cursor one character to the left.
+    \row \i Shift+Left Arrow \i Moves and selects text one character to the left.
+    \row \i Right Arrow \i Moves the cursor one character to the right.
+    \row \i Shift+Right Arrow \i Moves and selects text one character to the right.
+    \row \i Home \i Moves the cursor to the beginning of the line.
+    \row \i End \i Moves the cursor to the end of the line.
+    \row \i Backspace \i Deletes the character to the left of the cursor.
+    \row \i Ctrl+Backspace \i Deletes the word to the left of the cursor.
+    \row \i Delete \i Deletes the character to the right of the cursor.
+    \row \i Ctrl+Delete \i Deletes the word to the right of the cursor.
+    \row \i Ctrl+A \i Moves the cursor to the beginning of the line.
+    \row \i Ctrl+B \i Moves the cursor one character to the left.
+    \row \i Ctrl+C \i Copies the selected text to the clipboard.
+		      (Windows also supports Ctrl+Insert for this operation.)
+    \row \i Ctrl+D \i Deletes the character to the right of the cursor.
+    \row \i Ctrl+E \i Moves the cursor to the end of the line.
+    \row \i Ctrl+F \i Moves the cursor one character to the right.
+    \row \i Ctrl+H \i Deletes the character to the left of the cursor.
+    \row \i Ctrl+K \i Deletes to the end of the line.
+    \row \i Ctrl+V \i Pastes the clipboard text into line edit.
+		      (Windows also supports Shift+Insert for this operation.)
+    \row \i Ctrl+X \i Deletes the selected text and copies it to the clipboard.
+		      (Windows also supports Shift+Delete for this operation.)
+    \row \i Ctrl+Z \i Undoes the last operation.
+    \row \i Ctrl+Y \i Redoes the last undone operation.
+    \endtable
+
+    Any other key sequence that represents a valid character, will
+    cause the character to be inserted into the line edit.

+    \class QListBox qlistbox.h
+    \brief The QListBox widget provides a list of selectable, read-only items.
+
+    \ingroup advanced
+    \mainclass
+
+    This is typically a single-column list in which either no item or
+    one item is selected, but it can also be used in many other ways.
+
+    QListBox will add scroll bars as necessary, but it isn't intended
+    for \e really big lists. If you want more than a few thousand
+    items, it's probably better to use a different widget mainly
+    because the scroll bars won't provide very good navigation, but
+    also because QListBox may become slow with huge lists. (See
+    QListView and QTable for possible alternatives.)
+
+    There are a variety of selection modes described in the
+    QListBox::SelectionMode documentation. The default is \c Single
+    selection mode, but you can change it using setSelectionMode().
+    (setMultiSelection() is still provided for compatibility with Qt
+    1.x. We recommend using setSelectionMode() in all code.)
+
+    Because QListBox offers multiple selection it must display
+    keyboard focus and selection state separately. Therefore there are
+    functions both to set the selection state of an item, i.e.
+    setSelected(), and to set which item displays keyboard focus, i.e.
+    setCurrentItem().
+
+    The list box normally arranges its items in a single column and
+    adds a vertical scroll bar if required. It is possible to have a
+    different fixed number of columns (setColumnMode()), or as many
+    columns as will fit in the list box's assigned screen space
+    (setColumnMode(FitToWidth)), or to have a fixed number of rows
+    (setRowMode()) or as many rows as will fit in the list box's
+    assigned screen space (setRowMode(FitToHeight)). In all these
+    cases QListBox will add scroll bars, as appropriate, in at least
+    one direction.
+
+    If multiple rows are used, each row can be as high as necessary
+    (the normal setting), or you can request that all items will have
+    the same height by calling setVariableHeight(FALSE). The same
+    applies to a column's width, see setVariableWidth().
+
+    The QListBox's items are QListBoxItem objects. QListBox provides
+    methods to insert new items as strings, as pixmaps, and as
+    QListBoxItem * (insertItem() with various arguments), and to
+    replace an existing item with a new string, pixmap or QListBoxItem
+    (changeItem() with various arguments). You can also remove items
+    singly with removeItem() or clear() the entire list box. Note that
+    if you create a QListBoxItem yourself and insert it, QListBox
+    takes ownership of the item.
+
+    You can also create a QListBoxItem, such as QListBoxText or
+    QListBoxPixmap, with the list box as first parameter. The item
+    will then append itself. When you delete an item it is
+    automatically removed from the list box.
+
+    The list of items can be arbitrarily large; QListBox will add
+    scroll bars if necessary. QListBox can display a single-column
+    (the common case) or multiple-columns, and offers both single and
+    multiple selection. QListBox does not support multiple-column
+    items (but QListView and QTable do), or tree hierarchies (but
+    QListView does).
+
+    The list box items can be accessed both as QListBoxItem objects
+    (recommended) and using integer indexes (the original QListBox
+    implementation used an array of strings internally, and the API
+    still supports this mode of operation). Everything can be done
+    using the new objects, and most things can be done using indexes.
+
+    Each item in a QListBox contains a QListBoxItem. One of the items
+    can be the current item. The currentChanged() signal and the
+    highlighted() signal are emitted when a new item becomes current,
+    e.g. because the user clicks on it or QListBox::setCurrentItem()
+    is called. The selected() signal is emitted when the user
+    double-clicks on an item or presses Enter on the current item.
+
+    If the user does not select anything, no signals are emitted and
+    currentItem() returns -1.
+
+    A list box has \c WheelFocus as a default focusPolicy(), i.e. it
+    can get keyboard focus by tabbing, clicking and through the use of
+    the mouse wheel.
+
+    New items can be inserted using insertItem(), insertStrList() or
+    insertStringList(). inSort() is obsolete because this method is
+    quite inefficient. It's preferable to insert the items normally
+    and call sort() afterwards, or to insert a sorted QStringList().
+
+    By default, vertical and horizontal scroll bars are added and
+    removed as necessary. setHScrollBarMode() and setVScrollBarMode()
+    can be used to change this policy.
+
+    If you need to insert types other than strings and pixmaps, you
+    must define new classes which inherit QListBoxItem.
+
+    \warning The list box assumes ownership of all list box items and
+    will delete them when it does not need them any more.

+    \enum QListBox::SelectionMode
+
+    This enumerated type is used by QListBox to indicate how it reacts
+    to selection by the user.
+
+    \value Single  When the user selects an item, any already-selected
+    item becomes unselected and the user cannot unselect the selected
+    item. This means that the user can never clear the selection, even
+    though the selection may be cleared by the application programmer
+    using QListBox::clearSelection().
+
+    \value Multi  When the user selects an item the selection status
+    of that item is toggled and the other items are left alone. Also,
+    multiple items can be selected by dragging the mouse while the
+    left mouse button is kept pressed.
+
+    \value Extended When the user selects an item the selection is
+    cleared and the new item selected. However, if the user presses
+    the Ctrl key when clicking on an item, the clicked item gets
+    toggled and all other items are left untouched. And if the user
+    presses the Shift key while clicking on an item, all items between
+    the current item and the clicked item get selected or unselected,
+    depending on the state of the clicked item. Also, multiple items
+    can be selected by dragging the mouse while the left mouse button
+    is kept pressed.
+
+    \value NoSelection  Items cannot be selected.
+
+    In other words, \c Single is a real single-selection list box, \c
+    Multi is a real multi-selection list box, \c Extended is a list
+    box in which users can select multiple items but usually want to
+    select either just one or a range of contiguous items, and \c
+    NoSelection is for a list box where the user can look but not

+    \class QListViewItem
+    \brief The QListViewItem class implements a list view item.
+
+    \ingroup advanced
+
+    A list view item is a multi-column object capable of displaying
+    itself in a QListView.
+
+    The easiest way to use QListViewItem is to construct one with a
+    few constant strings, and either a QListView or another
+    QListViewItem as parent.
+    \code
+	(void) new QListViewItem( listView, "Column 1", "Column 2" );
+	(void) new QListViewItem( listView->firstChild(), "A", "B", "C" );
+    \endcode
+    We've discarded the pointers to the items since we can still access
+    them via their parent \e listView. By default, QListView sorts its
+    items; this can be switched off with QListView::setSorting(-1).
+
+    The parent must be another QListViewItem or a QListView. If the
+    parent is a QListView, the item becomes a top-level item within
+    that QListView. If the parent is another QListViewItem, the item
+    becomes a child of that list view item.
+
+    If you keep the pointer, you can set or change the texts using
+    setText(), add pixmaps using setPixmap(), change its mode using
+    setSelectable(), setSelected(), setOpen() and setExpandable().
+    You'll also be able to change its height using setHeight(), and
+    traverse its sub-items. You don't have to keep the pointer since
+    you can get a pointer to any QListViewItem in a QListView using
+    QListView::selectedItem(), QListView::currentItem(),
+    QListView::firstChild(), QListView::lastItem() and
+    QListView::findItem().
+
+    If you call \c delete on a list view item, it will be deleted as
+    expected, and as usual for \l{QObject}s, if it has any child items
+    (to any depth), all these will be deleted too.
+
+    \l{QCheckListItem}s are list view items that have a checkbox or
+    radio button and can be used in place of plain QListViewItems.
+
+    You can traverse the tree as if it were a doubly-linked list using
+    itemAbove() and itemBelow(); they return pointers to the items
+    directly above and below this item on the screen (even if none of
+    them are actually visible at the moment).
+
+    Here's how to traverse all of an item's children (but not its
+    children's children, etc.):
+    Example:
+    \code
+	QListViewItem * myChild = myItem->firstChild();
+	while( myChild ) {
+	    doSomething( myChild );
+	    myChild = myChild->nextSibling();
+	}
+    \endcode
+
+    If you want to iterate over every item, to any level of depth use
+    an iterator. To iterate over the entire tree, initialize the
+    iterator with the list view itself; to iterate starting from a
+    particular item, initialize the iterator with the item:
+
+    \code
+	QListViewItemIterator it( listview );
+	while ( it.current() ) {
+	    QListViewItem *item = it.current();
+	    doSomething( item );
+	    ++it;
+	}
+    \endcode
+
+    Note that the order of the children will change when the sorting
+    order changes and is undefined if the items are not visible. You
+    can, however, call enforceSortOrder() at any time; QListView will
+    always call it before it needs to show an item.
+
+    Many programs will need to reimplement QListViewItem. The most
+    commonly reimplemented functions are:
+    \table
+    \header \i Function \i Description
+    \row \i \l text()
+	 \i Returns the text in a column. Many subclasses will compute
+	    this on the fly.
+    \row \i \l key()
+	 \i Used for sorting. The default key() simply calls
+	    text(), but judicious use of key() can give you fine
+	    control over sorting; for example, QFileDialog
+	    reimplements key() to sort by date.
+    \row \i \l setup()
+	 \i Called before showing the item and whenever the list
+	    view's font changes, for example.
+    \row \i \l activate()
+	 \i Called whenever the user clicks on the item or presses
+	    Space when the item is the current item.
+    \endtable
+
+    Some subclasses call setExpandable(TRUE) even when they have no
+    children, and populate themselves when setup() or setOpen(TRUE) is
+    called. The \c dirview/dirview.cpp example program uses this
+    technique to start up quickly: The files and subdirectories in a
+    directory aren't inserted into the tree until they're actually
+    needed.

+
+    (From \link xml/tagreader-with-features/structureparser.cpp
+    xml/tagreader-with-features/structureparser.cpp\endlink)
+
+    The main setup functions are:
+    \table
+    \header \i Function \i Action
+    \row \i \l addColumn()
+	 \i Adds a column with a text label and perhaps width. Columns
+	    are counted from the left starting with column 0.
+    \row \i \l setColumnWidthMode()
+	 \i Sets the column to be resized automatically or not.
+    \row \i \l setAllColumnsShowFocus()
+	 \i Sets whether items should show keyboard focus using all
+	    columns or just column 0. The default is to show focus
+	    just using column 0.
+    \row \i \l setRootIsDecorated()
+	 \i Sets whether root items should show open/close decoration to their left.
+	    The default is FALSE.
+    \row \i \l setTreeStepSize()
+	 \i Sets how many pixels an item's children are indented
+	    relative to their parent. The default is 20. This is
+	    mostly a matter of taste.
+    \row \i \l setSorting()
+	 \i Sets whether the items should be sorted, whether it should
+	    be in ascending or descending order, and by what column
+	    they should be sorted. By default the list view is sorted
+	    by the first column; to switch this off call setSorting(-1).
+    \endtable
+
+    To handle events such as mouse presses on the list view, derived
+    classes can reimplement the QScrollView functions:
+    \link QScrollView::contentsMousePressEvent() contentsMousePressEvent\endlink,
+    \link QScrollView::contentsMouseReleaseEvent() contentsMouseReleaseEvent\endlink,
+    \link QScrollView::contentsMouseDoubleClickEvent() contentsMouseDoubleClickEvent\endlink,
+    \link QScrollView::contentsMouseMoveEvent() contentsMouseMoveEvent\endlink,
+    \link QScrollView::contentsDragEnterEvent() contentsDragEnterEvent\endlink,
+    \link QScrollView::contentsDragMoveEvent() contentsDragMoveEvent\endlink,
+    \link QScrollView::contentsDragLeaveEvent() contentsDragLeaveEvent\endlink,
+    \link QScrollView::contentsDropEvent() contentsDropEvent\endlink, and
+    \link QScrollView::contentsWheelEvent() contentsWheelEvent\endlink.
+
+    There are also several functions for mapping between items and
+    coordinates. itemAt() returns the item at a position on-screen,
+    itemRect() returns the rectangle an item occupies on the screen,
+    and itemPos() returns the position of any item (whether it is
+    on-screen or not). firstChild() returns the list view's first item
+    (not necessarily visible on-screen).
+
+    You can iterate over visible items using
+    QListViewItem::itemBelow(); over a list view's top-level items
+    using QListViewItem::firstChild() and
+    QListViewItem::nextSibling(); or every item using a
+    QListViewItemIterator. See
+    the QListViewItem documentation for examples of traversal.
+
+    An item can be moved amongst its siblings using
+    QListViewItem::moveItem(). To move an item in the hierarchy use
+    takeItem() and insertItem(). Item's (and all their child items)
+    are deleted with \c delete; to delete all the list view's items
+    use clear().
+
+    There are a variety of selection modes described in the
+    QListView::SelectionMode documentation. The default is \c Single
+    selection, which you can change using setSelectionMode().
+
+    Because QListView offers multiple selection it must display
+    keyboard focus and selection state separately. Therefore there are
+    functions both to set the selection state of an item
+    (setSelected()) and to set which item displays keyboard focus
+    (setCurrentItem()).
+
+    QListView emits two groups of signals; one group signals changes
+    in selection/focus state and one indicates selection. The first
+    group consists of selectionChanged() (applicable to all list
+    views), selectionChanged(QListViewItem*) (applicable only to a
+    \c Single selection list view), and currentChanged(QListViewItem*).
+    The second group consists of doubleClicked(QListViewItem*),
+    returnPressed(QListViewItem*),
+    rightButtonClicked(QListViewItem*, const QPoint&, int), etc.
+
+    Note that changing the state of the list view in a slot connected
+    to a list view signal may cause unexpected side effects. If you
+    need to change the list view's state in response to a signal, use
+    a \link QTimer::singleShot() single shot timer\endlink with a
+    time out of 0, and connect this timer to a slot that modifies the
+    list view's state.
+
+    In Motif style, QListView deviates fairly strongly from the look
+    and feel of the Motif hierarchical tree view. This is done mostly
+    to provide a usable keyboard interface and to make the list view
+    look better with a white background.
+
+    If selectionMode() is \c Single (the default) the user can select
+    one item at a time, e.g. by clicking an item with the mouse, see
+    \l QListView::SelectionMode for details.
+
+    The list view can be navigated either using the mouse or the
+    keyboard. Clicking a <b>-</b> icon closes an item (hides its
+    children) and clicking a <b>+</b> icon opens an item (shows its
+    children). The keyboard controls are these:
+    \table
+    \header \i Keypress \i Action
+    \row \i Home
+	 \i Make the first item current and visible.
+    \row \i End
+	 \i Make the last item current and visible.
+    \row \i Page Up
+	 \i Make the item above the top visible item current and visible.
+    \row \i Page Down
+	 \i Make the item below the bottom visible item current and visible.
+    \row \i Up Arrow
+	 \i Make the item above the current item current and visible.
+    \row \i Down Arrow
+	 \i Make the item below the current item current and visible.
+    \row \i Left Arrow
+	 \i If the current item is closed (<b>+</b> icon) or has no
+	    children, make its parent item current and visible. If the
+	    current item is open (<b>-</b> icon) close it, i.e. hide its
+	    children. Exception: if the current item is the first item
+	    and is closed and the horizontal scrollbar is offset to
+	    the right the list view will be scrolled left.
+    \row \i Right Arrow
+	 \i If the current item is closed (<b>+</b> icon) and has
+	    children, the item is opened. If the current item is
+	    opened (<b>-</b> icon) and has children the item's first
+	    child is made current and visible. If the current item has
+	    no children the list view is scrolled right.
+    \endtable
+
+    If the user starts typing letters with the focus in the list view
+    an incremental search will occur. For example if the user types
+    'd' the current item will change to the first item that begins
+    with the letter 'd'; if they then type 'a', the current item will
+    change to the first item that begins with 'da', and so on. If no
+    item begins with the letters they type the current item doesn't
+    change.
+
+    \warning The list view assumes ownership of all list view items
+    and will delete them when it does not need them any more.

+    \class QListViewItemIterator
+    \brief The QListViewItemIterator class provides an iterator for collections of QListViewItems.
+
+    \ingroup advanced
+
+    Construct an instance of a QListViewItemIterator, with either a
+    QListView* or a QListViewItem* as argument, to operate on the tree
+    of QListViewItems, starting from the argument.
+
+    A QListViewItemIterator iterates over all the items from its
+    starting point. This means that it always makes the first child of
+    the current item the new current item. If there is no child, the
+    next sibling becomes the new current item; and if there is no next
+    sibling, the next sibling of the parent becomes current.
+
+    The following example creates a list of all the items that have
+    been selected by the user, storing pointers to the items in a
+    QPtrList:
+    \code
+    QPtrList<QListViewItem> lst;
+    QListViewItemIterator it( myListView );
+    while ( it.current() ) {
+	if ( it.current()->isSelected() )
+	    lst.append( it.current() );
+	++it;
+    }
+    \endcode
+
+    An alternative approach is to use an \c IteratorFlag:
+    \code
+    QPtrList<QListViewItem> lst;
+    QListViewItemIterator it( myListView, QListViewItemIterator::Selected );
+    while ( it.current() ) {
+	lst.append( it.current() );
+	++it;
+    }
+    \endcode
+
+    A QListViewItemIterator provides a convenient and easy way to
+    traverse a hierarchical QListView.
+
+    Multiple QListViewItemIterators can operate on the tree of
+    QListViewItems. A QListView knows about all iterators operating on
+    its QListViewItems. So when a QListViewItem gets removed all
+    iterators that point to this item are updated and point to the
+    following item if possible, otherwise to a valid item before the
+    current one or to 0. Note however that deleting the parent item of
+    an item that an iterator points to is not safe.

+    \class QMainWindow qmainwindow.h
+    \brief The QMainWindow class provides a main application window,
+    with a menu bar, dock windows (e.g. for toolbars), and a status
+    bar.
+
+    \ingroup application
+    \mainclass
+
+    Main windows are most often used to provide menus, toolbars and a
+    status bar around a large central widget, such as a text edit,
+    drawing canvas or QWorkspace (for MDI applications). QMainWindow
+    is usually subclassed since this makes it easier to encapsulate
+    the central widget, menus and toolbars as well as the window's
+    state. Subclassing makes it possible to create the slots that are
+    called when the user clicks menu items or toolbar buttons. You can
+    also create main windows using \link designer-manual.book Qt
+    Designer\endlink. We'll briefly review adding menu items and
+    toolbar buttons then describe the facilities of QMainWindow
+    itself.
+
+    \code
+    QMainWindow *mw = new QMainWindow;
+    QTextEdit *edit = new QTextEdit( mw, "editor" );
+    edit->setFocus();
+    mw->setCaption( "Main Window" );
+    mw->setCentralWidget( edit );
+    mw->show();
+    \endcode
+
+    QMainWindows may be created in their own right as shown above.
+    The central widget is set with setCentralWidget(). Popup menus can
+    be added to the default menu bar, widgets can be added to the
+    status bar, toolbars and dock windows can be added to any of the
+    dock areas.
+
+    \quotefile application/main.cpp
+    \skipto ApplicationWindow
+    \printuntil show
+
+    In the extract above ApplicationWindow is a subclass of
+    QMainWindow that we must write for ourselves; this is the usual
+    approach to using QMainWindow. (The source for the extracts in
+    this description are taken from \l application/main.cpp, \l
+    application/application.cpp, \l action/main.cpp, and \l
+    action/application.cpp )
+
+    When subclassing we add the menu items and toolbars in the
+    subclass's constructor. If we've created a QMainWindow instance
+    directly we can add menu items and toolbars just as easily by
+    passing the QMainWindow instance as the parent instead of the \e
+    this pointer.
+
+    \quotefile application/application.cpp
+    \skipto help = new
+    \printuntil about
+
+    Here we've added a new menu with one menu item. The menu has been
+    inserted into the menu bar that QMainWindow provides by default
+    and which is accessible through the menuBar() function. The slot
+    will be called when the menu item is clicked.
+
+    \quotefile application/application.cpp
+    \skipto fileTools
+    \printuntil setLabel
+    \skipto QToolButton
+    \printuntil open file
+
+    This extract shows the creation of a toolbar with one toolbar
+    button. QMainWindow supplies four dock areas for toolbars. When a
+    toolbar is created as a child of a QMainWindow (or derived class)
+    instance it will be placed in a dock area (the \c Top dock area by
+    default). The slot will be called when the toolbar button is
+    clicked. Any dock window can be added to a dock area either using
+    addDockWindow(), or by creating a dock window with the QMainWindow
+    as the parent.
+
+    \quotefile application/application.cpp
+    \skipto editor
+    \printuntil statusBar
+
+    Having created the menus and toolbar we create an instance of the
+    large central widget, give it the focus and set it as the main
+    window's central widget. In the example we've also set the status
+    bar, accessed via the statusBar() function, to an initial message
+    which will be displayed for two seconds. Note that you can add
+    additional widgets to the status bar, for example labels, to show
+    further status information. See the QStatusBar documentation for
+    details, particularly the addWidget() function.
+
+    Often we want to synchronize a toolbar button with a menu item.
+    For example, if the user clicks a 'bold' toolbar button we want
+    the 'bold' menu item to be checked. This synchronization can be
+    achieved automatically by creating actions and adding the actions
+    to the toolbar and menu.
+
+    \quotefile action/application.cpp
+    \skipto QAction * fileOpen
+    \printline
+    \skipto fileOpenAction
+    \printuntil choose
+
+    Here we create an action with an icon which will be used in any
+    menu and toolbar that the action is added to. We've also given the
+    action a menu name, '\&Open', and a keyboard shortcut. The
+    connection that we have made will be used when the user clicks
+    either the menu item \e or the toolbar button.
+
+    \quotefile action/application.cpp
+    \skipto QPopupMenu * file
+    \printuntil menuBar
+    \skipto fileOpen
+    \printline
+
+    The extract above shows the creation of a popup menu. We add the
+    menu to the QMainWindow's menu bar and add our action.
+
+    \quotefile action/application.cpp
+    \skipto QToolBar * fileTool
+    \printuntil OpenAction
+
+    Here we create a new toolbar as a child of the QMainWindow and add
+    our action to the toolbar.
+
+    We'll now explore the functionality offered by QMainWindow.
+
+    The main window will take care of the dock areas, and the geometry
+    of the central widget, but all other aspects of the central widget
+    are left to you. QMainWindow automatically detects the creation of
+    a menu bar or status bar if you specify the QMainWindow as parent,
+    or you can use the provided menuBar() and statusBar() functions.
+    The functions menuBar() and statusBar() create a suitable widget
+    if one doesn't exist, and update the window's layout to make
+    space.
+
+    QMainWindow provides a QToolTipGroup connected to the status bar.
+    The function toolTipGroup() provides access to the default
+    QToolTipGroup. It isn't possible to set a different tool tip
+    group.
+
+    New dock windows and toolbars can be added to a QMainWindow using
+    addDockWindow(). Dock windows can be moved using moveDockWindow()
+    and removed with removeDockWindow(). QMainWindow allows default
+    dock window (toolbar) docking in all its dock areas (\c Top, \c
+    Left, \c Right, \c Bottom). You can use setDockEnabled() to
+    enable and disable docking areas for dock windows. When adding or
+    moving dock windows you can specify their 'edge' (dock area). The
+    currently available edges are: \c Top, \c Left, \c Right, \c
+    Bottom, \c Minimized (effectively a 'hidden' dock area) and \c
+    TornOff (floating). See \l Qt::Dock for an explanation of these
+    areas. Note that the *ToolBar functions are included for backward
+    compatibility; all new code should use the *DockWindow functions.
+    QToolbar is a subclass of QDockWindow so all functions that work
+    with dock windows work on toolbars in the same way.
+
+    \target dwm
+    If the user clicks the close button, then the dock window is
+    hidden. A dock window can be hidden or unhidden by the user by
+    right clicking a dock area and clicking the name of the relevant
+    dock window on the pop up dock window menu. This menu lists the
+    names of every dock window; visible dock windows have a tick
+    beside their names. The dock window menu is created automatically
+    as required by createDockWindowMenu(). Since it may not always be
+    appropriate for a dock window to appear on this menu the
+    setAppropriate() function is used to inform the main window
+    whether or not the dock window menu should include a particular
+    dock window. Double clicking a dock window handle (usually on the
+    left-hand side of the dock window) undocks (floats) the dock
+    window. Double clicking a floating dock window's titlebar will
+    dock the floating dock window. (See also
+    \l{QMainWindow::DockWindows}.)
+
+    Some functions change the appearance of a QMainWindow globally:

+    \i QDockWindow::setHorizontalStretchable() and

+
+    The user can drag dock windows into any enabled docking area. Dock
+    windows can also be dragged \e within a docking area, for example
+    to rearrange the order of some toolbars. Dock windows can also be
+    dragged outside any docking area (undocked or 'floated'). Being
+    able to drag dock windows can be enabled (the default) and
+    disabled using setDockWindowsMovable().
+
+    The \c Minimized edge is a hidden dock area. If this dock area is
+    enabled the user can hide (minimize) a dock window or show (restore)
+    a minimized dock window by clicking the dock window handle. If the
+    user hovers the mouse cursor over one of the handles, the caption of
+    the dock window is displayed in a tool tip (see
+    QDockWindow::caption() or QToolBar::label()), so if you enable the
+    \c Minimized dock area, it is best to specify a meaningful caption
+    or label for each dock window. To minimize a dock window
+    programmatically use moveDockWindow() with an edge of \c Minimized.
+
+    Dock windows are moved transparently by default, i.e. during the
+    drag an outline rectangle is drawn on the screen representing the
+    position of the dock window as it moves. If you want the dock
+    window to be shown normally whilst it is moved use
+    setOpaqueMoving().
+
+    The location of a dock window, i.e. its dock area and position
+    within the dock area, can be determined by calling getLocation().
+    Movable dock windows can be lined up to minimize wasted space with
+    lineUpDockWindows(). Pointers to the dock areas are available from
+    topDock(), leftDock(), rightDock() and bottomDock(). A customize
+    menu item is added to the pop up dock window menu if
+    isCustomizable() returns TRUE; it returns FALSE by default.
+    Reimplement isCustomizable() and customize() if you want to offer
+    this extra menu item, for example, to allow the user to change
+    settings relating to the main window and its toolbars and dock
+    windows.
+
+    The main window's menu bar is fixed (at the top) by default. If
+    you want a movable menu bar, create a QMenuBar as a stretchable
+    widget inside its own movable dock window and restrict this dock
+    window to only live within the \c Top or \c Bottom dock:
+
+    \code
+    QToolBar *tb = new QToolBar( this );
+    addDockWindow( tb, tr( "Menubar" ), Top, FALSE );
+    QMenuBar *mb = new QMenuBar( tb );
+    mb->setFrameStyle( QFrame::NoFrame );
+    tb->setStretchableWidget( mb );
+    setDockEnabled( tb, Left, FALSE );
+    setDockEnabled( tb, Right, FALSE );
+    \endcode
+
+    An application with multiple dock windows can choose to save the
+    current dock window layout in order to restore it later, e.g. in
+    the next session. You can do this by using the streaming operators
+    for QMainWindow.
+
+    To save the layout and positions of all the dock windows do this:
+
+    \code
+    QFile file( filename );
+    if ( file.open( IO_WriteOnly ) ) {
+	QTextStream stream( &file );
+	stream << *mainWindow;
+	file.close();
+    }
+    \endcode
+
+    To restore the dock window positions and sizes (normally when the
+    application is next started), do following:
+
+    \code
+    QFile file( filename );
+    if ( file.open( IO_ReadOnly ) ) {
+	QTextStream stream( &file );
+	stream >> *mainWindow;
+	file.close();
+    }
+    \endcode
+
+    The QSettings class can be used in conjunction with the streaming
+    operators to store the application's settings.
+
+    QMainWindow's management of dock windows and toolbars is done
+    transparently behind-the-scenes by QDockArea.
+
+    For multi-document interfaces (MDI), use a QWorkspace as the
+    central widget.
+
+    Adding dock windows, e.g. toolbars, to QMainWindow's dock areas is
+    straightforward. If the supplied dock areas are not sufficient for
+    your application we suggest that you create a QWidget subclass and
+    add your own dock areas (see \l QDockArea) to the subclass since
+    QMainWindow provides functionality specific to the standard dock
+    areas it provides.

+    The menu items representing the toolbars and dock windows are
+    checkable. The visible dock windows are checked and the hidden
+    dock windows are unchecked. The user can click a menu item to
+    change its state (show or hide the dock window).
+
+    The list and the state are always kept up-to-date.
+
+    Toolbars and dock windows which are not appropriate in the current
+    context (see setAppropriate()) are not listed in the menu.
+
+    The menu also has a menu item for lining up the dock windows.
+
+    If isCustomizable() returns TRUE, a Customize menu item is added
+    to the menu, which if clicked will call customize(). The
+    isCustomizable() function we provide returns FALSE and customize()
+    does nothing, so they must be reimplemented in a subclass to be
+    useful.

+    \class QMenuBar qmenubar.h
+    \brief The QMenuBar class provides a horizontal menu bar.
+
+    \ingroup application
+    \mainclass
+
+    A menu bar consists of a list of pull-down menu items. You add
+    menu items with \link QMenuData::insertItem()
+    insertItem()\endlink. For example, asuming that \c menubar is a
+    pointer to a QMenuBar and \c filemenu is a pointer to a
+    QPopupMenu, the following statement inserts the menu into the menu
+    bar:
+    \code
+    menubar->insertItem( "&File", filemenu );
+    \endcode
+    The ampersand in the menu item's text sets Alt+F as a shortcut for
+    this menu. (You can use "\&\&" to get a real ampersand in the menu
+    bar.)
+
+    Items are either enabled or disabled. You toggle their state with
+    setItemEnabled().
+
+    There is no need to lay out a menu bar. It automatically sets its
+    own geometry to the top of the parent widget and changes it
+    appropriately whenever the parent is resized.
+
+    \important insertItem removeItem clear insertSeparator setItemEnabled isItemEnabled setItemVisible isItemVisible
+
+    Example of creating a menu bar with menu items (from \l menu/menu.cpp):
+    \quotefile menu/menu.cpp
+    \skipto file = new QPopupMenu
+    \printline
+    \skipto Key_O
+    \printline
+    \printline
+    \skipto new QMenuBar
+    \printline
+    \skipto insertItem
+    \printline
+
+    In most main window style applications you would use the menuBar()
+    provided in QMainWindow, adding \l{QPopupMenu}s to the menu bar
+    and adding \l{QAction}s to the popup menus.
+
+    Example (from \l action/application.cpp):
+    \quotefile action/application.cpp
+    \skipto file = new QPopupMenu
+    \printuntil fileNewAction
+
+    Menu items can have text and pixmaps (or iconsets), see the
+    various \link QMenuData::insertItem() insertItem()\endlink
+    overloads, as well as separators, see \link
+    QMenuData::insertSeparator() insertSeparator()\endlink. You can
+    also add custom menu items that are derived from
+    \l{QCustomMenuItem}.
+
+    Menu items may be removed with removeItem() and enabled or
+    disabled with \link QMenuData::setItemEnabled()
+    setItemEnabled()\endlink.

+
+    \section1 QMenuBar on Qt/Mac
+
+    QMenuBar on Qt/Mac is a wrapper for using the system-wide menubar.
+    If you have multiple menubars in one dialog the outermost menubar
+    (normally inside a widget with widget flag \c WType_TopLevel) will
+    be used for the system-wide menubar.
+
+    Note that arbitrary Qt widgets \e cannot be inserted into a
+    QMenuBar on the Mac because Qt uses Mac's native menus which don't
+    support this functionality. This limitation does not apply to
+    stand-alone QPopupMenus.
+
+    Qt/Mac also provides a menubar merging feature to make QMenuBar
+    conform more closely to accepted Mac OS X menubar layout. The
+    merging functionality is based on string matching the title of a
+    QPopupMenu entry. These strings are translated (using
+    QObject::tr()) in the "QMenuBar" context. If an entry is moved its
+    slots will still fire as if it was in the original place. The
+    table below outlines the strings looked for and where the entry is
+    placed if matched:
+
+    \table
+    \header \i String matches \i Placement \i Notes
+    \row \i about.*
+	 \i Application Menu | About <application name>
+	 \i If this entry is not found no About item will appear in
+	    the Application Menu
+    \row \i config, options, setup, settings or preferences
+	 \i Application Menu | Preferences
+	 \i If this entry is not found the Settings item will be disabled
+    \row \i quit or exit
+	 \i Application Menu | Quit <application name>
+	 \i If this entry is not found a default Quit item will be
+	    created to call QApplication::quit()
+    \endtable
+
+    \link menu-example.html menu/menu.cpp\endlink is an example of
+    QMenuBar and QPopupMenu use.

+    \class QMenuData qmenudata.h
+    \brief The QMenuData class is a base class for QMenuBar and QPopupMenu.
+
+    \ingroup misc
+
+    QMenuData has an internal list of menu items. A menu item can have
+    a text(), an \link accel() accelerator\endlink, a pixmap(), an
+    iconSet(), a whatsThis() text and a popup menu (unless it is a
+    separator). Menu items may optionally be \link setItemChecked()
+    checked\endlink (except for separators).
+
+    The menu item sends out an \link QMenuBar::activated()
+    activated()\endlink signal when it is chosen and a \link
+    QMenuBar::highlighted() highlighted()\endlink signal when it
+    receives the user input focus.
+
+    \keyword menu identifier
+
+    Menu items are assigned the menu identifier \e id that is passed
+    in insertItem() or an automatically generated identifier if \e id
+    is < 0 (the default). The generated identifiers (negative
+    integers) are guaranteed to be unique within the entire
+    application. The identifier is used to access the menu item in
+    other functions.
+
+    Menu items can be removed with removeItem() and removeItemAt(), or
+    changed with changeItem(). All menu items can be removed with
+    clear(). Accelerators can be changed or set with setAccel().
+    Checkable items can be checked or unchecked with setItemChecked().
+    Items can be enabled or disabled using setItemEnabled() and
+    connected and disconnected with connectItem() and disconnectItem()
+    respectively. By default, newly created menu items are visible.
+    They can be hidden (and shown again) with setItemVisible().
+
+    Menu items are stored in a list. Use findItem() to find an item by
+    its list position or by its menu identifier. (See also indexOf()
+    and idAt().)

+/*!
+    The family of insertItem() functions inserts menu items into a
+    popup menu or a menu bar.
+
+    A menu item is usually either a text string or a pixmap, both with
+    an optional icon or keyboard accelerator. For special cases it is
+    also possible to insert custom items (see \l{QCustomMenuItem}) or
+    even widgets into popup menus.
+
+    Some insertItem() members take a popup menu as an additional
+    argument. Use this to insert submenus into existing menus or
+    pulldown menus into a menu bar.
+
+    The number of insert functions may look confusing, but they are
+    actually quite simple to use.
+
+    This default version inserts a menu item with the text \a text,
+    the accelerator key \a accel, an id and an optional index and
+    connects it to the slot \a member in the object \a receiver.
+
+    Example:
+    \code
+	QMenuBar   *mainMenu = new QMenuBar;
+	QPopupMenu *fileMenu = new QPopupMenu;
+	fileMenu->insertItem( "New",  myView, SLOT(newFile()), CTRL+Key_N );
+	fileMenu->insertItem( "Open", myView, SLOT(open()),    CTRL+Key_O );
+	mainMenu->insertItem( "File", fileMenu );
+    \endcode
+
+    Not all insert functions take an object/slot parameter or an
+    accelerator key. Use connectItem() and setAccel() on those items.
+
+    If you need to translate accelerators, use tr() with the text and
+    accelerator. (For translations use a string \link QKeySequence key
+    sequence\endlink.):
+    \code
+	fileMenu->insertItem( tr("Open"), myView, SLOT(open()),
+			      tr("Ctrl+O") );
+    \endcode
+
+    In the example above, pressing Ctrl+O or selecting "Open" from the
+    menu activates the myView->open() function.
+
+    Some insert functions take a QIconSet parameter to specify the
+    little menu item icon. Note that you can always pass a QPixmap
+    object instead.
+
+    The \a id specifies the identification number associated with the
+    menu item. Note that only positive values are valid, as a negative
+    value will make Qt select a unique id for the item.
+
+    The \a index specifies the position in the menu. The menu item is
+    appended at the end of the list if \a index is negative.
+
+    Note that keyboard accelerators in Qt are not application-global,
+    instead they are bound to a certain top-level window. For example,
+    accelerators in QPopupMenu items only work for menus that are
+    associated with a certain window. This is true for popup menus
+    that live in a menu bar since their accelerators will then be
+    installed in the menu bar itself. This also applies to stand-alone
+    popup menus that have a top-level widget in their parentWidget()
+    chain. The menu will then install its accelerator object on that
+    top-level widget. For all other cases use an independent QAccel
+    object.
+
+    \warning Be careful when passing a literal 0 to insertItem()
+    because some C++ compilers choose the wrong overloaded function.
+    Cast the 0 to what you mean, e.g. \c{(QObject*)0}.
+
+    \warning On Mac OS X, items that connect to a slot that are inserted into a
+    menubar will not function as we use the native menubar that knows nothing
+    about signals or slots. Instead insert the items into a popup menu and
+    insert the popup menu into the menubar. This may be fixed in a future Qt
+    version.

+/*!
+    Sets the accelerator key for the menu item \a id to \a key.
+
+    An accelerator key consists of a key code and a combination of the
+    modifiers \c SHIFT, \c CTRL, \c ALT or \c UNICODE_ACCEL (OR'ed or
+    added). The header file \c qnamespace.h contains a list of key
+    codes.
+
+    Defining an accelerator key produces a text that is added to the
+    menu item; for instance, \c CTRL + \c Key_O produces "Ctrl+O". The
+    text is formatted differently for different platforms.
+
+    Note that keyboard accelerators in Qt are not application-global,
+    instead they are bound to a certain top-level window. For example,
+    accelerators in QPopupMenu items only work for menus that are
+    associated with a certain window. This is true for popup menus
+    that live in a menu bar since their accelerators will then be
+    installed in the menu bar itself. This also applies to stand-alone
+    popup menus that have a top-level widget in their parentWidget()
+    chain. The menu will then install its accelerator object on that
+    top-level widget. For all other cases use an independent QAccel
+    object.
+
+    Example:
+    \code
+	QMenuBar *mainMenu = new QMenuBar;
+	QPopupMenu *fileMenu = new QPopupMenu;       // file sub menu
+	fileMenu->insertItem( "Open Document", 67 ); // add "Open" item
+	fileMenu->setAccel( CTRL + Key_O, 67 );      // Ctrl+O to open
+	fileMenu->insertItem( "Quit", 69 );          // add "Quit" item
+	fileMenu->setAccel( CTRL + ALT + Key_Delete, 69 ); // add Alt+Del to quit
+	mainMenu->insertItem( "File", fileMenu );    // add the file menu
+    \endcode
+
+    If you need to translate accelerators, use tr() with a string:
+    \code
+	fileMenu->setAccel( tr("Ctrl+O"), 67 );
+    \endcode
+
+    You can also specify the accelerator in the insertItem() function.
+    You may prefer to use QAction to associate accelerators with menu
+    items.

+    \class QCustomMenuItem qmenudata.h
+    \brief The QCustomMenuItem class is an abstract base class for custom menu items in popup menus.
+
+    \ingroup misc
+
+    A custom menu item is a menu item that is defined by two pure
+    virtual functions, paint() and sizeHint(). The size hint tells the
+    menu how much space it needs to reserve for this item, and paint
+    is called whenever the item needs painting.
+
+    This simple mechanism allows you to create all kinds of
+    application specific menu items. Examples are items showing
+    different fonts in a word processor or menus that allow the
+    selection of drawing utilities in a vector drawing program.
+
+    A custom item is inserted into a popup menu with
+    QPopupMenu::insertItem().
+
+    By default, a custom item can also have an icon and a keyboard
+    accelerator. You can reimplement fullSpan() to return TRUE if you
+    want the item to span the entire popup menu width. This is
+    particularly useful for labels.
+
+    If you want the custom item to be treated just as a separator,
+    reimplement isSeparator() to return TRUE.
+
+    Note that you can insert pixmaps or bitmaps as items into a popup
+    menu without needing to create a QCustomMenuItem. However, custom
+    menu items offer more flexibility, and -- especially important
+    with Windows style -- provide the possibility of drawing the item
+    with a different color when it is highlighted.
+
+    \link menu-example.html menu/menu.cpp\endlink shows a simple
+    example how custom menu items can be used.
+
+    Note: the current implementation of QCustomMenuItem will not
+    recognize shortcut keys that are from text with ampersands. Normal
+    accelerators work though.

+  \class QMultiLineEdit qmultilineedit.h
+  \obsolete
+
+  \brief The QMultiLineEdit widget is a simple editor for inputting text.
+
+  \ingroup advanced
+
+  The QMultiLineEdit was a simple editor widget in former Qt versions.  Qt
+  3.0 includes a new richtext engine which obsoletes QMultiLineEdit. It is
+  still included for compatibility reasons. It is now a subclass of
+  \l QTextEdit, and provides enough of the old QMultiLineEdit API to keep old
+  applications working.
+
+  If you implement something new with QMultiLineEdit, we suggest using
+  \l QTextEdit instead and call QTextEdit::setTextFormat(Qt::PlainText).
+
+  Although most of the old QMultiLineEdit API is still available, there is
+  a few difference. The old QMultiLineEdit operated on lines, not on
+  paragraphs.  As lines change all the time during wordwrap, the new
+  richtext engine uses paragraphs as basic elements in the data structure.
+  All functions (numLines(), textLine(), etc.) that operated on lines, now
+  operate on paragraphs. Further, getString() has been removed completely.
+  It revealed too much of the internal data structure.
+
+  Applications which made normal and reasonable use of QMultiLineEdit
+  should still work without problems. Some odd usage will require some
+  porting. In these cases, it may be better to use \l QTextEdit now.

+    \class QPopupMenu qpopupmenu.h
+    \brief The QPopupMenu class provides a popup menu widget.
+
+    \ingroup application
+    \ingroup basic
+    \mainclass
+
+    A popup menu widget is a selection menu. It can be either a
+    pull-down menu in a menu bar or a standalone context (popup) menu.
+    Pull-down menus are shown by the menu bar when the user clicks on
+    the respective item or presses the specified shortcut key. Use
+    QMenuBar::insertItem() to insert a popup menu into a menu bar.
+    Show a context menu either asynchronously with popup() or
+    synchronously with exec().
+
+    Technically, a popup menu consists of a list of menu items. You
+    add items with insertItem(). An item is either a string, a pixmap
+    or a custom item that provides its own drawing function (see
+    QCustomMenuItem). In addition, items can have an optional icon
+    drawn on the very left side and an accelerator key such as
+    "Ctrl+X".
+
+    There are three kinds of menu items: separators, menu items that
+    perform an action and menu items that show a submenu. Separators
+    are inserted with insertSeparator(). For submenus, you pass a
+    pointer to a QPopupMenu in your call to insertItem(). All other
+    items are considered action items.
+
+    When inserting action items you usually specify a receiver and a
+    slot. The receiver will be notifed whenever the item is selected.
+    In addition, QPopupMenu provides two signals, activated() and
+    highlighted(), which signal the identifier of the respective menu
+    item. It is sometimes practical to connect several items to one
+    slot. To distinguish between them, specify a slot that takes an
+    integer argument and use setItemParameter() to associate a unique
+    value with each item.
+
+    You clear a popup menu with clear() and remove single items with
+    removeItem() or removeItemAt().
+
+    A popup menu can display check marks for certain items when
+    enabled with setCheckable(TRUE). You check or uncheck items with
+    setItemChecked().
+
+    Items are either enabled or disabled. You toggle their state with
+    setItemEnabled(). Just before a popup menu becomes visible, it
+    emits the aboutToShow() signal. You can use this signal to set the
+    correct enabled/disabled states of all menu items before the user
+    sees it. The corresponding aboutToHide() signal is emitted when
+    the menu hides again.
+
+    You can provide What's This? help for single menu items with
+    setWhatsThis(). See QWhatsThis for general information about this
+    kind of lightweight online help.
+
+    For ultimate flexibility, you can also add entire widgets as items
+    into a popup menu (for example, a color selector).
+
+    A QPopupMenu can also provide a tear-off menu. A tear-off menu is
+    a top-level window that contains a copy of the menu. This makes it
+    possible for the user to "tear off" frequently used menus and
+    position them in a convenient place on the screen. If you want
+    that functionality for a certain menu, insert a tear-off handle
+    with insertTearOffHandle(). When using tear-off menus, bear in
+    mind that the concept isn't typically used on Microsoft Windows so
+    users may not be familiar with it. Consider using a QToolBar
+    instead. Tear-off menus cannot contain custom widgets; if the
+    original menu contains a custom widget item, this item is omitted.
+
+    \link menu-example.html menu/menu.cpp\endlink is an example of
+    QMenuBar and QPopupMenu use.

+    Opens the popup menu so that the item number \a indexAtPoint will
+    be at the specified \e global position \a pos. To translate a
+    widget's local coordinates into global coordinates, use
+    QWidget::mapToGlobal().
+
+    The return code is the id of the selected item in either the popup
+    menu or one of its submenus, or -1 if no item is selected
+    (normally because the user pressed Esc).
+
+    Note that all signals are emitted as usual. If you connect a menu
+    item to a slot and call the menu's exec(), you get the result both
+    via the signal-slot connection and in the return value of exec().
+
+    Common usage is to position the popup at the current mouse
+    position:
+    \code
+	exec( QCursor::pos() );
+    \endcode
+    or aligned to a widget:
+    \code
+	exec( somewidget.mapToGlobal(QPoint(0, 0)) );
+    \endcode
+
+    When positioning a popup with exec() or popup(), bear in mind that
+    you cannot rely on the popup menu's current size(). For
+    performance reasons, the popup adapts its size only when
+    necessary. So in many cases, the size before and after the show is
+    different. Instead, use sizeHint(). It calculates the proper size
+    depending on the menu's current contents.

+    progress of an operation and to reassure them that the application
+    is still running.
+
+    The progress bar uses the concept of \e steps; you give it the
+    total number of steps and the number of steps completed so far and
+    it will display the percentage of steps that have been completed.
+    You can specify the total number of steps in the constructor or
+    later with setTotalSteps(). The current number of steps is set
+    with setProgress(). The progress bar can be rewound to the
+    beginning with reset().
+
+    If the total is given as 0 the progress bar shows a busy indicator
+    instead of a percentage of steps. This is useful, for example,
+    when using QFtp or QHttp to download items when they are unable to
+    determine the size of the item being downloaded.

+    \class QPushButton qpushbutton.h
+    \brief The QPushButton widget provides a command button.
+
+    \ingroup basic
+    \mainclass
+
+    The push button, or command button, is perhaps the most commonly
+    used widget in any graphical user interface. Push (click) a button
+    to command the computer to perform some action, or to answer a
+    question. Typical buttons are OK, Apply, Cancel, Close, Yes, No
+    and Help.
+
+    A command button is rectangular and typically displays a text
+    label describing its action. An underlined character in the label
+    (signified by preceding it with an ampersand in the text)
+    indicates an accelerator key, e.g.
+    \code
+	QPushButton *pb = new QPushButton( "&Download", this );
+    \endcode
+    In this example the accelerator is \e{Alt+D}, and the label text
+    will be displayed as <b><u>D</u>ownload</b>.
+
+    Push buttons can display a textual label or a pixmap, and
+    optionally a small icon. These can be set using the constructors
+    and changed later using setText(), setPixmap() and setIconSet().
+    If the button is disabled the appearance of the text or pixmap and
+    iconset will be manipulated with respect to the GUI style to make
+    the button look "disabled".
+
+    A push button emits the signal clicked() when it is activated by
+    the mouse, the Spacebar or by a keyboard accelerator. Connect to
+    this signal to perform the button's action. Push buttons also
+    provide less commonly used signals, for example, pressed() and
+    released().
+
+    Command buttons in dialogs are by default auto-default buttons,
+    i.e. they become the default push button automatically when they
+    receive the keyboard input focus. A default button is a push
+    button that is activated when the user presses the Enter or Return
+    key in a dialog. You can change this with setAutoDefault(). Note
+    that auto-default buttons reserve a little extra space which is
+    necessary to draw a default-button indicator. If you do not want
+    this space around your buttons, call setAutoDefault(FALSE).
+
+    Being so central, the button widget has grown to accommodate a
+    great many variations in the past decade. The Microsoft style
+    guide now shows about ten different states of Windows push buttons
+    and the text implies that there are dozens more when all the
+    combinations of features are taken into consideration.
+
+    The most important modes or states are:
+    \list
+    \i Available or not (grayed out, disabled).
+    \i Standard push button, toggling push button or menu button.
+    \i On or off (only for toggling push buttons).
+    \i Default or normal. The default button in a dialog can generally
+       be "clicked" using the Enter or Return key.
+    \i Auto-repeat or not.
+    \i Pressed down or not.
+    \endlist
+
+    As a general rule, use a push button when the application or
+    dialog window performs an action when the user clicks on it (such
+    as Apply, Cancel, Close and Help) \e and when the widget is
+    supposed to have a wide, rectangular shape with a text label.
+    Small, typically square buttons that change the state of the
+    window rather than performing an action (such as the buttons in
+    the top-right corner of the QFileDialog) are not command buttons,
+    but tool buttons. Qt provides a special class (QToolButton) for
+    these buttons.
+
+    If you need toggle behavior (see setToggleButton()) or a button
+    that auto-repeats the activation signal when being pushed down
+    like the arrows in a scroll bar (see setAutoRepeat()), a command
+    button is probably not what you want. When in doubt, use a tool
+    button.
+
+    A variation of a command button is a menu button. These provide
+    not just one command, but several, since when they are clicked
+    they pop up a menu of options. Use the method setPopup() to
+    associate a popup menu with a push button.
+
+    Other classes of buttons are option buttons (see QRadioButton) and
+    check boxes (see QCheckBox).
+
+    <img src="qpushbt-m.png"> <img src="qpushbt-w.png">
+
+    In Qt, the QButton abstract base class provides most of the modes
+    and other API, and QPushButton provides GUI logic. See QButton for
+    more information about the API.

+    \class QRadioButton qradiobutton.h
+    \brief The QRadioButton widget provides a radio button with a text or pixmap label.
+
+    \ingroup basic
+    \mainclass
+
+    QRadioButton and QCheckBox are both option buttons. That is, they
+    can be switched on (checked) or off (unchecked). The classes
+    differ in how the choices for the user are restricted. Check boxes
+    define "many of many" choices, whereas radio buttons provide a
+    "one of many" choice. In a group of radio buttons only one radio
+    button at a time can be checked; if the user selects another
+    button, the previously selected button is switched off.
+
+    The easiest way to implement a "one of many" choice is simply to
+    put the radio buttons into QButtonGroup.
+
+    Whenever a button is switched on or off it emits the signal
+    toggled(). Connect to this signal if you want to trigger an action
+    each time the button changes state. Otherwise, use isChecked() to
+    see if a particular button is selected.
+
+    Just like QPushButton, a radio button can display text or a
+    pixmap. The text can be set in the constructor or with setText();
+    the pixmap is set with setPixmap().

+    \class QRangeControl qrangecontrol.h
+    \brief The QRangeControl class provides an integer value within a range.
+
+    \ingroup misc
+
+    Although originally designed for the QScrollBar widget, the
+    QRangeControl can also be used in conjunction with other widgets
+    such as QSlider and QSpinBox. Here are the five main concepts in
+    the class:
+
+    \list 1
+
+    \i \e{Current value} The bounded integer that
+    QRangeControl maintains. value() returns it, and several
+    functions, including setValue(), set it.
+
+    \i \e{Minimum} The lowest value that value() can ever
+    return. Returned by minValue() and set by setRange() or one of the
+    constructors.
+
+    \i \e{Maximum} The highest value that value() can ever
+    return. Returned by maxValue() and set by setRange() or one of the
+    constructors.
+
+    \i \e{Line step} The smaller of two natural steps that
+    QRangeControl provides and typically corresponds to the user
+    pressing an arrow key. The line step is returned by lineStep()
+    and set using setSteps(). The functions addLine() and
+    subtractLine() respectively increment and decrement the current
+    value by lineStep().
+
+    \i \e{Page step} The larger of two natural steps that
+    QRangeControl provides and typically corresponds to the user
+    pressing PageUp or PageDown. The page step is returned by
+    pageStep() and set using setSteps(). The functions addPage() and
+    substractPage() respectively increment and decrement the current
+    value by pageStep().
+
+    \endlist
+
+    Unity (1) may be viewed as a third step size. setValue() lets you
+    set the current value to any integer in the allowed range, not
+    just minValue() + \e n * lineStep() for integer values of \e n.
+    Some widgets may allow the user to set any value at all; others
+    may just provide multiples of lineStep() or pageStep().
+
+    QRangeControl provides three virtual functions that are well
+    suited for updating the on-screen representation of range controls
+    and emitting signals: valueChange(), rangeChange() and
+    stepChange().
+
+    QRangeControl also provides a function called bound() which lets
+    you force arbitrary integers to be within the allowed range of the
+    range control.
+
+    We recommend that all widgets that inherit QRangeControl provide
+    at least a signal called valueChanged(); many widgets will want to
+    provide addStep(), addPage(), substractStep() and substractPage()
+    as slots.
+
+    Note that you must use multiple inheritance if you plan to
+    implement a widget using QRangeControl because QRangeControl is
+    not derived from QWidget.

+    created, this is the same as value().
+
+    prevValue() can be outside the current legal range if a call to
+    setRange() causes the current value to change. For example, if the

+/*!
+    \class QScrollBar
+    \brief The QScrollBar widget provides a vertical or horizontal scroll bar.
+
+    \ingroup basic
+
+    A scroll bar allows the user to control a value within a
+    program-definable range and gives users a visible indication of
+    the current value of a \link QRangeControl range control \endlink.
+
+    Scroll bars include four separate controls:
+
+    \list
+
+    \i The \e line-up and \e line-down controls are little buttons
+    which the user can use to move one "line" up or down. The meaning
+    of line is configurable. In editors and list boxes it means one
+    line of text; in an image viewer it might mean 20 pixels.
+
+    \i The \e slider is the handle that indicates the current value of
+    the scroll bar, which the user can drag to change the value. This
+    part of the scroll bar is sometimes called the "thumb".
+
+    \i The \e page-up/page-down control is the area on which the
+    slider slides (the scroll bar's background). Clicking here moves
+    the scroll bar towards the click. The meaning of "page" is also
+    configurable: in editors and list boxes it means as many lines as
+    there is space for in the widget.
+
+    \endlist
+
+    QScrollBar has very few of its own functions; it mostly relies on
+    QRangeControl. The most useful functions are setValue() to set the
+    scroll bar directly to some value; addPage(), addLine(),
+    subtractPage(), and subtractLine() to simulate the effects of
+    clicking (useful for accelerator keys); setSteps() to define the
+    values of pageStep() and lineStep(); and setRange() to set the
+    minValue() and maxValue() of the scroll bar. QScrollBar has a
+    convenience constructor with which you can set most of these
+    properties.
+
+    Some GUI styles (for example, the Windows and Motif styles
+    provided with Qt), also use the pageStep() value to calculate the
+    size of the slider.
+
+    In addition to the access functions from QRangeControl, QScrollBar
+    provides a comprehensive set of signals:
+    \table
+    \header \i Signal \i Emitted when
+    \row \i \l valueChanged()
+	 \i the scroll bar's value has changed. The tracking()
+	    determines whether this signal is emitted during user
+	    interaction.
+    \row \i \l sliderPressed()
+	 \i the user starts to drag the slider.
+    \row \i \l sliderMoved()
+	 \i the user drags the slider.
+    \row \i \l sliderReleased()
+	 \i the user releases the slider.
+    \row \i \l nextLine()
+	 \i the scroll bar has moved one line down or right. Line is
+	    defined in QRangeControl.
+    \row \i \l prevLine()
+	 \i the scroll bar has moved one line up or left.
+    \row \i \l nextPage()
+	 \i the scroll bar has moved one page down or right.
+    \row \i \l prevPage()
+	 \i the scroll bar has moved one page up or left.
+    \endtable
+
+    QScrollBar only provides integer ranges. Note that although
+    QScrollBar handles very large numbers, scroll bars on current
+    screens cannot usefully control ranges above about 100,000 pixels.
+    Beyond that, it becomes difficult for the user to control the
+    scroll bar using either the keyboard or the mouse.
+
+    A scroll bar can be controlled by the keyboard, but it has a
+    default focusPolicy() of \c NoFocus. Use setFocusPolicy() to
+    enable keyboard focus. See keyPressEvent() for a list of key
+    bindings.
+
+    If you need to add scroll bars to an interface, consider using the
+    QScrollView class, which encapsulates the common uses for scroll
+    bars.

+    \class QScrollView qscrollview.h
+    \brief The QScrollView widget provides a scrolling area with on-demand scroll bars.
+
+    \ingroup abstractwidgets
+    \mainclass
+
+    The QScrollView is a large canvas - potentially larger than the
+    coordinate system normally supported by the underlying window
+    system. This is important because it is quite easy to go beyond
+    these limitations (e.g. many web pages are more than 32000 pixels
+    high). Additionally, the QScrollView can have QWidgets positioned
+    on it that scroll around with the drawn content. These sub-widgets
+    can also have positions outside the normal coordinate range (but
+    they are still limited in size).
+
+    To provide content for the widget, inherit from QScrollView,
+    reimplement drawContents() and use resizeContents() to set the
+    size of the viewed area. Use addChild() and moveChild() to
+    position widgets on the view.
+
+    To use QScrollView effectively it is important to understand its
+    widget structure in the three styles of use: a single large child
+    widget, a large panning area with some widgets and a large panning
+    area with many widgets.
+
+    \section1 Using One Big Widget
+
+    \img qscrollview-vp2.png
+
+    The first, simplest usage of QScrollView (depicted above), is
+    appropriate for scrolling areas that are never more than about
+    4000 pixels in either dimension (this is about the maximum
+    reliable size on X11 servers). In this usage, you just make one
+    large child in the QScrollView. The child should be a child of the
+    viewport() of the scrollview and be added with addChild():
+    \code
+	QScrollView* sv = new QScrollView(...);
+	QVBox* big_box = new QVBox(sv->viewport());
+	sv->addChild(big_box);
+    \endcode
+    You can go on to add arbitrary child widgets to the single child
+    in the scrollview as you would with any widget:
+    \code
+	QLabel* child1 = new QLabel("CHILD", big_box);
+	QLabel* child2 = new QLabel("CHILD", big_box);
+	QLabel* child3 = new QLabel("CHILD", big_box);
+	...
+    \endcode
+
+    Here the QScrollView has four children: the viewport(), the
+    verticalScrollBar(), the horizontalScrollBar() and a small
+    cornerWidget(). The viewport() has one child: the big QVBox. The
+    QVBox has the three QLabel objects as child widgets. When the view
+    is scrolled, the QVBox is moved; its children move with it as
+    child widgets normally do.
+
+    \section1 Using a Very Big View with Some Widgets
+
+    \img qscrollview-vp.png
+
+    The second usage of QScrollView (depicted above) is appropriate
+    when few, if any, widgets are on a very large scrolling area that
+    is potentially larger than 4000 pixels in either dimension. In
+    this usage you call resizeContents() to set the size of the area
+    and reimplement drawContents() to paint the contents. You may also
+    add some widgets by making them children of the viewport() and
+    adding them with addChild() (this is the same as the process for
+    the single large widget in the previous example):
+    \code
+	QScrollView* sv = new QScrollView(...);
+	QLabel* child1 = new QLabel("CHILD", sv->viewport());
+	sv->addChild(child1);
+	QLabel* child2 = new QLabel("CHILD", sv->viewport());
+	sv->addChild(child2);
+	QLabel* child3 = new QLabel("CHILD", sv->viewport());
+	sv->addChild(child3);
+    \endcode
+    Here, the QScrollView has the same four children: the viewport(),
+    the verticalScrollBar(), the horizontalScrollBar() and a small
+    cornerWidget(). The viewport() has the three QLabel objects as
+    child widgets. When the view is scrolled, the scrollview moves the
+    child widgets individually.
+
+    \section1 Using a Very Big View with Many Widgets
+
+    \target enableclipper
+    \img qscrollview-cl.png
+
+    The final usage of QScrollView (depicted above) is appropriate
+    when many widgets are on a very large scrolling area that is
+    potentially larger than 4000 pixels in either dimension. In this
+    usage you call resizeContents() to set the size of the area and
+    reimplement drawContents() to paint the contents. You then call
+    enableClipper(TRUE) and add widgets, again by making them children
+    of the viewport(), and adding them with addChild():
+    \code
+	QScrollView* sv = new QScrollView(...);
+	sv->enableClipper(TRUE);
+	QLabel* child1 = new QLabel("CHILD", sv->viewport());
+	sv->addChild(child1);
+	QLabel* child2 = new QLabel("CHILD", sv->viewport());
+	sv->addChild(child2);
+	QLabel* child3 = new QLabel("CHILD", sv->viewport());
+	sv->addChild(child3);
+    \endcode
+
+    Here, the QScrollView has four children:  the clipper() (not the
+    viewport() this time), the verticalScrollBar(), the
+    horizontalScrollBar() and a small cornerWidget(). The clipper()
+    has one child: the viewport(). The viewport() has the same three
+    labels as child widgets. When the view is scrolled the viewport()
+    is moved; its children move with it as child widgets normally do.
+
+    \target allviews
+    \section1 Details Relevant for All Views
+
+    Normally you will use the first or third method if you want any
+    child widgets in the view.
+
+    Note that the widget you see in the scrolled area is the
+    viewport() widget, not the QScrollView itself. So to turn mouse
+    tracking on, for example, use viewport()->setMouseTracking(TRUE).
+
+    To enable drag-and-drop, you would setAcceptDrops(TRUE) on the
+    QScrollView (because drag-and-drop events propagate to the
+    parent). But to work out the logical position in the view, you
+    would need to map the drop co-ordinate from being relative to the
+    QScrollView to being relative to the contents; use the function
+    viewportToContents() for this.
+
+    To handle mouse events on the scrolling area, subclass scrollview
+    as you would subclass other widgets, but rather than
+    reimplementing mousePressEvent(), reimplement
+    contentsMousePressEvent() instead. The contents specific event
+    handlers provide translated events in the coordinate system of the
+    scrollview. If you reimplement mousePressEvent(), you'll get
+    called only when part of the QScrollView is clicked: and the only
+    such part is the "corner" (if you don't set a cornerWidget()) and
+    the frame; everything else is covered up by the viewport, clipper
+    or scroll bars.
+
+    When you construct a QScrollView, some of the widget flags apply
+    to the viewport() instead of being sent to the QWidget constructor
+    for the QScrollView. This applies to \c WNoAutoErase, \c
+    WStaticContents, and \c WPaintClever. See \l Qt::WidgetFlags for
+    documentation about these flags. Here are some examples:
+
+    \list
+
+    \i An image-manipulation widget would use \c
+    WNoAutoErase|WStaticContents because the widget draws all pixels
+    itself, and when its size increases, it only needs a paint event
+    for the new part because the old part remains unchanged.
+
+    \i A scrolling game widget in which the background scrolls as the
+    characters move might use \c WNoAutoErase (in addition to \c
+    WStaticContents) so that the window system background does not
+    flash in and out during scrolling.
+
+    \i A word processing widget might use \c WNoAutoErase and repaint
+    itself line by line to get a less-flickery resizing. If the widget
+    is in a mode in which no text justification can take place, it
+    might use \c WStaticContents too, so that it would only get a
+    repaint for the newly visible parts.
+
+    \endlist
+
+    Child widgets may be moved using addChild() or moveChild(). Use
+    childX() and childY() to get the position of a child widget.
+
+    A widget may be placed in the corner between the vertical and
+    horizontal scrollbars with setCornerWidget(). You can get access
+    to the scrollbars using horizontalScrollBar() and
+    verticalScrollBar(), and to the viewport with viewport(). The
+    scroll view can be scrolled using scrollBy(), ensureVisible(),
+    setContentsPos() or center().
+
+    The visible area is given by visibleWidth() and visibleHeight(),
+    and the contents area by contentsWidth() and contentsHeight(). The
+    contents may be repainted using one of the repaintContents() or
+    updateContents() functions.
+
+    Coordinate conversion is provided by contentsToViewport() and
+    viewportToContents().
+
+    The contentsMoving() signal is emitted just before the contents
+    are moved to a new position.
+
+    \warning QScrollView currently does not erase the background when
+    resized, i.e. you must always clear the background manually in
+    scrollview subclasses. This will change in a future version of Qt
+    and we recommend specifying the WNoAutoErase flag explicitly.

+    \class QSlider
+    \brief The QSlider widget provides a vertical or horizontal slider.
+
+    \ingroup basic
+    \mainclass
+
+    The slider is the classic widget for controlling a bounded value.
+    It lets the user move a slider along a horizontal or vertical
+    groove and translates the slider's position into an integer value
+    within the legal range.
+
+    QSlider inherits QRangeControl, which provides the "integer" side
+    of the slider. setRange() and value() are likely to be used by
+    practically all slider users; see the \l QRangeControl
+    documentation for information about the many other functions that
+    class provides.
+
+    The main functions offered by the slider itself are tickmark and
+    orientation control; you can use setTickmarks() to indicate where
+    you want the tickmarks to be, setTickInterval() to indicate how
+    many of them you want and setOrientation() to indicate whether the
+    slider is to be horizontal or vertical.
+
+    A slider accepts focus on Tab and uses the mouse wheel and a
+    suitable keyboard interface.

+/*!
+    \class QSpinBox
+    \brief The QSpinBox class provides a spin box widget (spin button).
+
+    \ingroup basic
+    \mainclass
+
+    QSpinBox allows the user to choose a value either by clicking the
+    up/down buttons to increase/decrease the value currently displayed
+    or by typing the value directly into the spin box. If the value is
+    entered directly into the spin box, Enter (or Return) must be
+    pressed to apply the new value. The value is usually an integer.
+
+    Every time the value changes QSpinBox emits the valueChanged()
+    signal. The current value can be fetched with value() and set
+    with setValue().
+
+    The spin box keeps the value within a numeric range, and to
+    multiples of the lineStep() size (see QRangeControl for details).
+    Clicking the up/down buttons or using the keyboard accelerator's
+    up and down arrows will increase or decrease the current value in
+    steps of size lineStep(). The minimum and maximum value and the
+    step size can be set using one of the constructors, and can be
+    changed later with setMinValue(), setMaxValue() and setLineStep().
+
+    Most spin boxes are directional, but QSpinBox can also operate as
+    a circular spin box, i.e. if the range is 0-99 and the current
+    value is 99, clicking "up" will give 0. Use setWrapping() if you
+    want circular behavior.
+
+    The displayed value can be prepended and appended with arbitrary
+    strings indicating, for example, currency or the unit of
+    measurement. See setPrefix() and setSuffix(). The text in the spin
+    box is retrieved with text() (which includes any prefix() and
+    suffix()), or with cleanText() (which has no prefix(), no suffix()
+    and no leading or trailing whitespace). currentValueText() returns
+    the spin box's current value as text.
+
+    Normally the spin box displays up and down arrows in the buttons.
+    You can use setButtonSymbols() to change the display to show
+    <b>+</b> and <b>-</b> symbols if you prefer. In either case the up
+    and down arrow keys work as expected.
+
+    It is often desirable to give the user a special (often default)
+    choice in addition to the range of numeric values. See
+    setSpecialValueText() for how to do this with QSpinBox.
+
+    The default \l QWidget::focusPolicy() is StrongFocus.
+
+    If using prefix(), suffix() and specialValueText() don't provide
+    enough control, you can ignore them and subclass QSpinBox instead.
+
+    QSpinBox can easily be subclassed to allow the user to input
+    things other than an integer value as long as the allowed input
+    can be mapped to a range of integers. This can be done by
+    overriding the virtual functions mapValueToText() and
+    mapTextToValue(), and setting another suitable validator using
+    setValidator().
+
+    For example, these functions could be changed so that the user
+    provided values from 0.0 to 10.0, or -1 to signify 'Auto', while
+    the range of integers used inside the program would be -1 to 100:
+
+    \code
+	class MySpinBox : public QSpinBox
+	{
+	    Q_OBJECT
+	public:
+	    ...
+
+	    QString mapValueToText( int value )
+	    {
+		if ( value == -1 ) // special case
+		    return QString( "Auto" );
+
+		return QString( "%1.%2" ) // 0.0 to 10.0
+		    .arg( value / 10 ).arg( value % 10 );
+	    }
+
+	    int mapTextToValue( bool *ok )
+	    {
+		if ( text() == "Auto" ) // special case
+		    return -1;
+
+		return (int) ( 10 * text().toFloat() ); // 0 to 100
+	    }
+	};
+    \endcode

+    is to indicate that this choice has a special (default) meaning.
+
+    For example, if your spin box allows the user to choose the margin
+    width in a print dialog and your application is able to
+    automatically choose a good margin width, you can set up the spin
+    box like this:
+    \code

+    The user will then be able to choose a margin width from 0-20
+    millimeters or select "Auto" to leave it to the application to
+    choose. Your code must then interpret the spin box value of -1 as
+    the user requesting automatic margin width.
+
+    All values are displayed with the prefix() and suffix() (if set),
+    \e except for the special value, which only shows the special
+    value text.
+
+    To turn off the special-value text display, call this function
+    with an empty string. The default is no special-value text, i.e.

+   \class QSplashScreen qsplashscreen.h
+   \brief The QSplashScreen widget provides a splash screen that can
+   be shown during application startup.
+
+    \ingroup misc
+    \mainclass
+
+   A splash screen is a widget that is usually displayed when an
+   application is being started. Splash screens are often used for
+   applications that have long start up times (e.g. database or
+   networking applications that take time to establish connections) to
+   provide the user with feedback that the application is loading.
+
+   The splash screen appears centered on the screen. It may be useful to add
+   the \c WStyle_StaysOnTop if you desire to keep above all the windows in the
+   GUI.
+
+   Some X11 window managers do not support the "stays on top" flag. A
+   solution is to set up a timer that periodically calls raise() on
+   the splash screen to simulate the "stays on top" effect.
+
+   The most common usage is to show a splash screen before the main
+   widget is displayed on the screen. This is illustrated in the
+   following code snippet.
+
+   \code
+   int main( int argc, char **argv )
+   {
+       QApplication app( argc, argv );
+       QPixmap pixmap( "splash.png" );
+       QSplashScreen *splash = new QSplashScreen( pixmap );
+       splash->show();
+       QMainWindow *mainWin = new QMainWindow;
+       ...
+       app.setMainWidget( mainWin );
+       mainWin->show();
+       splash->finish( mainWin );
+       delete splash;
+       return app.exec();
+   }
+   \endcode
+
+   It is sometimes useful to update the splash screen with messages,
+   for example, announcing connections established or modules loaded
+   as the application starts up. QSplashScreen supports this with the
+   message() function. If you wish to do your own drawing you can
+   get a pointer to the pixmap used in the splash screen with pixmap().
+   Alternatively, you can subclass QSplashScreen and reimplement
+   drawContents().
+
+   The user can hide the splash screen by clicking on it with the
+   mouse. Since the splash screen is typically displayed before the
+   event loop has started running, it is necessary to periodically
+   call QApplication::processEvents() to receive the mouse clicks.
+
+   \code
+   QPixmap pixmap( "splash.png" );
+   QSplashScreen *splash = new QSplashScreen( pixmap );
+   splash->show();
+   ... // Loading some items
+   splash->message( "Loaded modules" );
+   qApp->processEvents();
+   ... // Establishing connections
+   splash->message( "Established connections" );
+   qApp->processEvents();
+   \endcode

+    \class QSplitter
+    \brief The QSplitter class implements a splitter widget.
+
+    \ingroup organizers
+    \mainclass
+
+    A splitter lets the user control the size of child widgets by
+    dragging the boundary between the children. Any number of widgets
+    may be controlled by a single splitter.
+
+    To show a QListBox, a QListView and a QTextEdit side by side:
+    \code
+	QSplitter *split = new QSplitter( parent );
+	QListBox *lb = new QListBox( split );
+	QListView *lv = new QListView( split );
+	QTextEdit *ed = new QTextEdit( split );
+    \endcode
+
+    QSplitter lays out its children horizontally (side by side); you
+    can use setOrientation(QSplitter::Vertical) to lay out the
+    children vertically.
+
+    By default, all widgets can be as large or as small as the user
+    wishes, between the \l minimumSizeHint() (or \l minimumSize())
+    and \l maximumSize() of the widgets. Use setResizeMode() to
+    specify that a widget should keep its size when the splitter is
+    resized, or set the stretch component of the \l sizePolicy.
+
+    Although QSplitter normally resizes the children only at the end
+    of a resize operation, if you call setOpaqueResize(TRUE) the
+    widgets are resized as often as possible.
+
+    The initial distribution of size between the widgets is determined
+    by the initial size of each widget. You can also use setSizes() to
+    set the sizes of all the widgets. The function sizes() returns the
+    sizes set by the user.
+
+    If you hide() a child its space will be distributed among the
+    other children. It will be reinstated when you show() it again. It
+    is also possible to reorder the widgets within the splitter using
+    moveToFirst() and moveToLast().

+/*!
+    \class QStatusBar qstatusbar.h
+    \brief The QStatusBar class provides a horizontal bar suitable for
+    presenting status information.
+
+    \ingroup application
+    \ingroup helpsystem
+    \mainclass
+
+    Each status indicator falls into one of three categories:
+
+    \list
+    \i \e Temporary - briefly occupies most of the status bar. Used
+	to explain tool tip texts or menu entries, for example.
+    \i \e Normal - occupies part of the status bar and may be hidden
+	by temporary messages. Used to display the page and line
+	number in a word processor, for example.
+    \i \e Permanent - is never hidden. Used for important mode
+	indications, for example, some applications put a Caps Lock
+	indicator in the status bar.
+    \endlist
+
+    QStatusBar lets you display all three types of indicators.
+
+    To display a \e temporary message, call message() (perhaps by
+    connecting a suitable signal to it). To remove a temporary
+    message, call clear(). There are two variants of message(): one
+    that displays the message until the next clear() or message() and
+    one that has a time limit:
+
+    \code
+	connect( loader, SIGNAL(progressMessage(const QString&)),
+		 statusBar(), SLOT(message(const QString&)) );
+
+	statusBar()->message("Loading...");  // Initial message
+	loader.loadStuff();                  // Emits progress messages
+	statusBar()->message("Done.", 2000); // Final message for 2 seconds
+    \endcode
+
+    \e Normal and \e Permanent messages are displayed by creating a
+    small widget and then adding it to the status bar with
+    addWidget(). Widgets like QLabel, QProgressBar or even QToolButton
+    are useful for adding to status bars. removeWidget() is used to
+    remove widgets.
+
+    \code
+	statusBar()->addWidget(new MyReadWriteIndication(statusBar()));
+    \endcode
+
+    By default QStatusBar provides a QSizeGrip in the lower-right
+    corner. You can disable it with setSizeGripEnabled(FALSE);

+/*!
+    \class QSyntaxHighlighter qsyntaxhighlighter.h
+    \brief The QSyntaxHighlighter class is a base class for
+    implementing QTextEdit syntax highlighters.
+
+    \ingroup basic
+    \ingroup text
+
+    A syntax highligher automatically highlights parts of the text in
+    a QTextEdit. Syntax highlighters are often used when the user is
+    entering text in a specific format (for example, source code) and
+    help the user to read the text and identify syntax errors.
+
+    To provide your own syntax highlighting for QTextEdit, you must
+    subclass QSyntaxHighlighter and reimplement highlightParagraph().
+
+    When you create an instance of your QSyntaxHighlighter subclass,
+    pass it the QTextEdit that you want the syntax highlighting to be
+    applied to. After this your highlightParagraph() function will be
+    called automatically whenever necessary. Use your
+    highlightParagraph() function to apply formatting (e.g. setting
+    the font and color) to the text that is passed to it.
+*/
+
+/*!
+    Constructs the QSyntaxHighlighter and installs it on \a textEdit.
+
+    It is the caller's responsibility to delete the
+    QSyntaxHighlighter when it is no longer needed.
+*/
+
+QSyntaxHighlighter::QSyntaxHighlighter( QTextEdit *textEdit )
+    : para( 0 ), edit( textEdit ), d( new QSyntaxHighlighterPrivate )
+{
+    textEdit->document()->setPreProcessor( new QSyntaxHighlighterInternal( this ) );
+    textEdit->document()->invalidate();
+    QTimer::singleShot( 0, textEdit->viewport(), SLOT( update() ) );
+}
+
+/*!
+    Destructor. Uninstalls this syntax highlighter from the textEdit()

+{
+    delete d;
+    textEdit()->document()->setPreProcessor( 0 );
+}
+
+/*!
+    \fn int QSyntaxHighlighter::highlightParagraph( const QString &text, int endStateOfLastPara )
+
+    This function is called when necessary by the rich text engine,
+    i.e. on paragraphs which have changed.
+
+    In your reimplementation you should parse the paragraph's \a text
+    and call setFormat() as often as necessary to apply any font and
+    color changes that you require. Your function must return a value
+    which indicates the paragraph's end state: see below.
+
+    Some syntaxes can have constructs that span paragraphs. For
+    example, a C++ syntax highlighter should be able to cope with
+    \c{/}\c{*...*}\c{/} comments that span paragraphs. To deal
+    with these cases it is necessary to know the end state of the
+    previous paragraph (e.g. "in comment").
+
+    If your syntax does not have paragraph spanning constructs, simply
+    ignore the \a endStateOfLastPara parameter and always return 0.
+
+    Whenever highlightParagraph() is called it is passed a value for
+    \a endStateOfLastPara. For the very first paragraph this value is
+    always -2. For any other paragraph the value is the value returned
+    by the most recent highlightParagraph() call that applied to the
+    preceding paragraph.
+
+    The value you return is up to you. We recommend only returning 0
+    (to signify that this paragraph's syntax highlighting does not
+    affect the following paragraph), or a positive integer (to signify
+    that this paragraph has ended in the middle of a paragraph
+    spanning construct).
+
+    To find out which paragraph is highlighted, call
+    currentParagraph().
+
+    For example, if you're writing a simple C++ syntax highlighter,
+    you might designate 1 to signify "in comment". For a paragraph
+    that ended in the middle of a comment you'd return 1, and for
+    other paragraphs you'd return 0. In your parsing code if \a
+    endStateOfLastPara was 1, you would highlight the text as a C++
+    comment until you reached the closing \c{*}\c{/}.
+*/
+
+/*!
+    This function is applied to the syntax highlighter's current
+    paragraph (the text of which is passed to the highlightParagraph()

+    \class QTabBar qtabbar.h
+    \brief The QTabBar class provides a tab bar, e.g. for use in tabbed dialogs.
+
+    \ingroup advanced
+
+    QTabBar is straightforward to use; it draws the tabs using one of
+    the predefined \link QTabBar::Shape shapes\endlink, and emits a
+    signal when a tab is selected. It can be subclassed to tailor the
+    look and feel. Qt also provides a ready-made \l{QTabWidget} and a
+    \l{QTabDialog}.
+
+    The choice of tab shape is a matter of taste, although tab dialogs
+    (for preferences and similar) invariably use \c RoundedAbove;
+    nobody uses \c TriangularAbove. Tab controls in windows other than
+    dialogs almost always use either \c RoundedBelow or \c
+    TriangularBelow. Many spreadsheets and other tab controls in which
+    all the pages are essentially similar use \c TriangularBelow,
+    whereas \c RoundedBelow is used mostly when the pages are
+    different (e.g. a multi-page tool palette).
+
+    The most important part of QTabBar's API is the selected() signal.
+    This is emitted whenever the selected page changes (even at
+    startup, when the selected page changes from 'none'). There is
+    also a slot, setCurrentTab(), which can be used to select a page
+    programmatically.
+
+    QTabBar creates automatic accelerator keys in the manner of
+    QButton; e.g. if a tab's label is "\&Graphics", Alt+G becomes an
+    accelerator key for switching to that tab.
+
+    The following virtual functions may need to be reimplemented:
+    \list
+    \i paint() paints a single tab. paintEvent() calls paint() for
+    each tab so that any overlap will look right.
+    \i addTab() creates a new tab and adds it to the bar.
+    \i selectTab() decides which tab, if any, the user selects with the mouse.
+    \endlist
+
+    The index of the current tab is returned by currentTab(). The tab
+    with a particular index is returned by tabAt(), the tab with a
+    particular id is returned by tab(). The index of a tab is returned
+    by indexOf(). The current tab can be set by index or tab pointer
+    using one of the setCurrentTab() functions.
+

+
+/*!
+    \enum QTabBar::Shape
+
+    This enum type lists the built-in shapes supported by QTabBar:
+
+    \value RoundedAbove  the normal rounded look above the pages
+
+    \value RoundedBelow  the normal rounded look below the pages
+
+    \value TriangularAbove  triangular tabs above the pages (very
+    unusual; included for completeness)
+
+    \value TriangularBelow  triangular tabs similar to those used in

+    \class QTabWidget qtabwidget.h
+    \brief The QTabWidget class provides a stack of tabbed widgets.
+
+    \ingroup organizers
+    \ingroup advanced
+    \mainclass
+
+    A tab widget provides a tab bar of tabs and a `page area' below
+    (or above, see \l{TabPosition}) the tabs. Each tab is associated
+    with a different widget (called a `page'). Only the current tab's
+    page is shown in the page area; all the other tabs' pages are
+    hidden. The user can show a different page by clicking on its tab
+    or by pressing its Alt+\e{letter} accelerator if it has one.
+
+    The normal way to use QTabWidget is to do the following in the
+    constructor:
+    \list 1
+    \i Create a QTabWidget.
+    \i Create a QWidget for each of the pages in the tab dialog,
+    insert children into it, set up geometry management for it and use
+    addTab() (or insertTab()) to set up a tab and keyboard accelerator
+    for it.
+    \i Connect to the signals and slots.
+    \endlist
+
+    The position of the tabs is set with setTabPosition(), their shape
+    with setTabShape(), and their margin with setMargin().
+
+    If you don't call addTab() and the QTabWidget is already visible,
+    then the page you have created will not be visible. Don't
+    confuse the object name you supply to the QWidget constructor and
+    the tab label you supply to addTab(). addTab() takes a name which
+    indicates an accelerator and is meaningful and descriptive to the
+    user, whereas the widget name is used primarily for debugging.
+
+    The signal currentChanged() is emitted when the user selects a
+    page.
+
+    The current page is available as an index position with
+    currentPageIndex() or as a wiget pointer with currentPage(). You
+    can retrieve a pointer to a page with a given index using page(),
+    and can find the index position of a page with indexOf(). Use
+    setCurrentPage() to show a particular page by index, or showPage()
+    to show a page by widget pointer.
+
+    You can change a tab's label and iconset using changeTab() or
+    setTabLabel() and setTabIconSet(). A tab page can be removed with
+    removePage().
+
+    Each tab is either enabled or disabled at any given time (see
+    setTabEnabled()). If a tab is enabled, the tab text is drawn
+    normally and the user can select that tab. If it is disabled, the
+    tab is drawn in a different way and the user cannot select that
+    tab. Note that even if a tab is disabled, the page can still be
+    visible, for example if all of the tabs happen to be disabled.
+
+    Although tab widgets can be a very good way to split up a complex
+    dialog, it's also very easy to get into a mess. See QTabDialog for
+    some design hints. An alternative is to use a QWidgetStack for
+    which you provide some means of navigating between pages, for
+    example, a QToolBar or a QListBox.
+
+    Most of the functionality in QTabWidget is provided by a QTabBar
+    (at the top, providing the tabs) and a QWidgetStack (most of the
+    area, organizing the individual pages).

+    \class QTextBrowser qtextbrowser.h
+    \brief The QTextBrowser class provides a rich text browser with hypertext navigation.
+
+    \ingroup advanced
+    \ingroup helpsystem
+    \ingroup text
+    \mainclass
+
+    This class extends QTextEdit (in read-only mode), adding some
+    navigation functionality so that users can follow links in
+    hypertext documents. The contents of QTextEdit is set with
+    setText(), but QTextBrowser has an additional function,
+    setSource(), which makes it possible to set the text to a named
+    document. The name is looked up in the text view's mime source
+    factory. If a document name ends with an anchor (for example, "\c
+    #anchor"), the text browser automatically scrolls to that position
+    (using scrollToAnchor()). When the user clicks on a hyperlink, the
+    browser will call setSource() itself, with the link's \c href
+    value as argument. You can track the current source by connetion
+    to the sourceChanged() signal.
+
+    QTextBrowser provides backward() and forward() slots which you can
+    use to implement Back and Forward buttons. The home() slot sets
+    the text to the very first document displayed. The linkClicked()
+    signal is emitted when the user clicks a link.
+
+    By using QTextEdit::setMimeSourceFactory() you can provide your
+    own subclass of QMimeSourceFactory. This makes it possible to
+    access data from anywhere, for example from a network or from a
+    database. See QMimeSourceFactory::data() for details.
+
+    If you intend using the mime factory to read the data directly
+    from the file system, you may have to specify the encoding for the
+    file extension you are using. For example:
+    \code
+    mimeSourceFactory()->setExtensionType("qml", "text/utf8");
+    \endcode
+    This is to ensure that the factory is able to resolve the document
+    names.
+
+    QTextBrowser interprets the tags it processes in accordance with
+    the default style sheet. Change the style sheet with
+    \l{setStyleSheet()}; see QStyleSheet for details.
+
+    If you want to provide your users with editable rich text use
+    QTextEdit. If you want a text browser without hypertext navigation
+    use QTextEdit, and use QTextEdit::setReadOnly() to disable
+    editing. If you just need to display a small piece of rich text
+    use QSimpleRichText or QLabel.

+    \brief The QTextEdit widget provides a powerful single-page rich text editor.
+

+
+    \tableofcontents
+
+    \section1 Introduction and Concepts
+
+    QTextEdit is an advanced WYSIWYG viewer/editor supporting rich
+    text formatting using HTML-style tags. It is optimized to handle
+    large documents and to respond quickly to user input.
+
+    QTextEdit has four modes of operation:
+    \table
+    \header \i Mode \i Command \i Notes
+    \row \i Plain Text Editor \i setTextFormat(PlainText)
+	 \i Set text with setText(); text() returns plain text. Text
+	 attributes (e.g. colors) can be set, but plain text is always
+	 returned.
+    \row \i Rich Text Editor \i setTextFormat(RichText)
+	 \i Set text with setText(); text() returns rich text. Rich
+	 text editing is fairly limited. You can't set margins or
+	 insert images for example (although you can read and
+	 correctly display files that have margins set and that
+	 include images). This mode is mostly useful for editing small
+	 amounts of rich text. <sup>1.</sup>
+    \row \i Text Viewer \i setReadOnly(TRUE)
+         \i Set text with setText() or append() (which has no undo
+	 history so is faster and uses less memory); text() returns
+	 plain or rich text depending on the textFormat(). This mode
+	 can correctly display a large subset of HTML tags.
+    \row \i Log Viewer \i setTextFormat(LogText)
+	 \i Append text using append(). The widget is set to be read
+	 only and rich text support is disabled although a few HTML
+	 tags (for color, bold, italic and underline) may be used.
+	 (See \link #logtextmode LogText mode\endlink for details.)
+    \endtable
+
+    <sup>1.</sup><small>A more complete API that supports setting
+    margins, images, etc., is planned for a later Qt release.</small>
+
+    QTextEdit can be used as a syntax highlighting editor when used in
+    conjunction with QSyntaxHighlighter.
+
+    We recommend that you always call setTextFormat() to set the mode
+    you want to use. If you use \c AutoText then setText() and
+    append() will try to determine whether the text they are given is
+    plain text or rich text. If you use \c RichText then setText() and
+    append() will assume that the text they are given is rich text.
+    insert() simply inserts the text it is given.
+
+    QTextEdit works on paragraphs and characters. A paragraph is a
+    formatted string which is word-wrapped to fit into the width of
+    the widget. By default when reading plain text, one newline
+    signify a paragraph. A document consists of zero or more
+    paragraphs, indexed from 0. Characters are indexed on a
+    per-paragraph basis, also indexed from 0. The words in the
+    paragraph are aligned in accordance with the paragraph's
+    alignment(). Paragraphs are separated by hard line breaks. Each
+    character within a paragraph has its own attributes, for example,
+    font and color.
+
+    The text edit documentation uses the following concepts:
+    \list
+    \i \e{current format} --
+    this is the format at the current cursor position, \e and it
+    is the format of the selected text if any.
+    \i \e{current paragraph} -- the paragraph which contains the
+    cursor.
+    \endlist
+
+    QTextEdit can display images (using QMimeSourceFactory), lists and
+    tables. If the text is too large to view within the text edit's
+    viewport, scrollbars will appear. The text edit can load both
+    plain text and HTML files (a subset of HTML 3.2 and 4). The
+    rendering style and the set of valid tags are defined by a
+    styleSheet(). Custom tags can be created and placed in a custom
+    style sheet. Change the style sheet with \l{setStyleSheet()}; see
+    QStyleSheet for details. The images identified by image tags are
+    displayed if they can be interpreted using the text edit's
+    \l{QMimeSourceFactory}; see setMimeSourceFactory().
+
+    If you want a text browser with more navigation use QTextBrowser.
+    If you just need to display a small piece of rich text use QLabel
+    or QSimpleRichText.
+
+    If you create a new QTextEdit, and want to allow the user to edit
+    rich text, call setTextFormat(Qt::RichText) to ensure that the
+    text is treated as rich text. (Rich text uses HTML tags to set
+    text formatting attributes. See QStyleSheet for information on the
+    HTML tags that are supported.). If you don't call setTextFormat()
+    explicitly the text edit will guess from the text itself whether
+    it is rich text or plain text. This means that if the text looks
+    like HTML or XML it will probably be interpreted as rich text, so
+    you should call setTextFormat(Qt::PlainText) to preserve such
+    text.
+
+    Note that we do not intend to add a full-featured web browser
+    widget to Qt (because that would easily double Qt's size and only
+    a few applications would benefit from it). The rich
+    text support in Qt is designed to provide a fast, portable and
+    efficient way to add reasonable online help facilities to
+    applications, and to provide a basis for rich text editors.
+
+    \section1 Using QTextEdit as a Display Widget
+
+    QTextEdit can display a large HTML subset, including tables and
+    images.
+
+    The text is set or replaced using setText() which deletes any
+    existing text and replaces it with the text passed in the
+    setText() call. If you call setText() with legacy HTML (with
+    setTextFormat(RichText) in force), and then call text(), the text
+    that is returned may have different markup, but will render the
+    same. Text can be inserted with insert(), paste(), pasteSubType()
+    and append(). Text that is appended does not go into the undo
+    history; this makes append() faster and consumes less memory. Text
+    can also be cut(). The entire text is deleted with clear() and the
+    selected text is deleted with removeSelectedText(). Selected
+    (marked) text can also be deleted with del() (which will delete
+    the character to the right of the cursor if no text is selected).
+
+    Loading and saving text is achieved using setText() and text(),
+    for example:
+    \code
+    QFile file( fileName ); // Read the text from a file
+    if ( file.open( IO_ReadOnly ) ) {
+	QTextStream stream( &file );
+	textEdit->setText( stream.read() );
+    }
+
+    QFile file( fileName ); // Write the text to a file
+    if ( file.open( IO_WriteOnly ) ) {
+	QTextStream stream( &file );
+	stream << textEdit->text();
+	textEdit->setModified( FALSE );
+    }
+    \endcode
+
+    By default the text edit wraps words at whitespace to fit within
+    the text edit widget. The setWordWrap() function is used to
+    specify the kind of word wrap you want, or \c NoWrap if you don't
+    want any wrapping. Call setWordWrap() to set a fixed pixel width
+    \c FixedPixelWidth, or character column (e.g. 80 column) \c
+    FixedColumnWidth with the pixels or columns specified with
+    setWrapColumnOrWidth(). If you use word wrap to the widget's width
+    \c WidgetWidth, you can specify whether to break on whitespace or
+    anywhere with setWrapPolicy().
+
+    The background color is set differently than other widgets, using
+    setPaper(). You specify a brush style which could be a plain color
+    or a complex pixmap.
+
+    Hypertext links are automatically underlined; this can be changed
+    with setLinkUnderline(). The tab stop width is set with
+    setTabStopWidth().
+
+    The zoomIn() and zoomOut() functions can be used to resize the
+    text by increasing (decreasing for zoomOut()) the point size used.
+    Images are not affected by the zoom functions.
+
+    The lines() function returns the number of lines in the text and
+    paragraphs() returns the number of paragraphs. The number of lines
+    within a particular paragraph is returned by linesOfParagraph().
+    The length of the entire text in characters is returned by
+    length().
+
+    You can scroll to an anchor in the text, e.g.
+    \c{<a name="anchor">} with scrollToAnchor(). The find() function
+    can be used to find and select a given string within the text.
+
+    A read-only QTextEdit provides the same functionality as the
+    (obsolete) QTextView. (QTextView is still supplied for
+    compatibility with old code.)
+
+    \section2 Read-only key bindings
+
+    When QTextEdit is used read-only the key-bindings are limited to
+    navigation, and text may only be selected with the mouse:
+    \table
+    \header \i Keypresses \i Action
+    \row \i UpArrow	\i Move one line up
+    \row \i DownArrow	\i Move one line down
+    \row \i LeftArrow	\i Move one character left
+    \row \i RightArrow	\i Move one character right
+    \row \i PageUp	\i Move one (viewport) page up
+    \row \i PageDown	\i Move one (viewport) page down
+    \row \i Home	\i Move to the beginning of the text
+    \row \i End		\i Move to the end of the text
+    \row \i Shift+Wheel
+	 \i Scroll the page horizontally (the Wheel is the mouse wheel)
+    \row \i Ctrl+Wheel	\i Zoom the text
+    \endtable
+
+    The text edit may be able to provide some meta-information. For
+    example, the documentTitle() function will return the text from
+    within HTML \c{<title>} tags.
+
+    The text displayed in a text edit has a \e context. The context is
+    a path which the text edit's QMimeSourceFactory uses to resolve
+    the locations of files and images. It is passed to the
+    mimeSourceFactory() when quering data. (See QTextEdit() and
+    \l{context()}.)
+
+    \target logtextmode
+    \section2 Using QTextEdit in LogText Mode
+
+    Setting the text format to \c LogText puts the widget in a special
+    mode which is optimized for very large texts. Editing, word wrap,
+    and rich text support are disabled in this mode (the widget is
+    explicitly made read-only). This allows the text to be stored in a
+    different, more memory efficient manner. However, a certain degree
+    of text formatting is supported through the use of formatting tags.
+    A tag is delimited by \c < and \c {>}. The characters \c {<}, \c >
+    and \c & are escaped by using \c {&lt;}, \c {&gt;} and \c {&amp;}.
+    A tag pair consists of a left and a right tag (or open/close tags).
+    Left-tags mark the starting point for formatting, while right-tags
+    mark the ending point. A right-tag always start with a \c / before
+    the tag keyword. For example \c <b> and \c </b> are a tag pair.
+    Tags can be nested, but they have to be closed in the same order as
+    they are opened. For example, \c <b><u></u></b> is valid, while \c
+    <b><u></b></u> will output an error message.
+
+    By using tags it is possible to change the color, bold, italic and
+    underline settings for a piece of text. A color can be specified
+    by using the HTML font tag \c {<font color=colorname>}. The color
+    name can be one of the color names from the X11 color database, or
+    a RGB hex value (e.g \c {#00ff00}). Example of valid color tags:
+    \c {<font color=red>}, \c {<font color="light blue">}, \c {<font
+    color="#223344">}. Bold, italic and underline settings can be
+    specified by the tags \c {<b>}, \c <i> and \c {<u>}. Note that a
+    tag does not necessarily have to be closed. A valid example:
+    \code
+    This is <font color=red>red</font> while <b>this</b> is <font color=blue>blue</font>.
+    <font color=green><font color=yellow>Yellow,</font> and <u>green</u>.
+    \endcode
+
+    Stylesheets can also be used in LogText mode. To create and use a
+    custom tag, you could do the following:
+    \code
+    QTextEdit * log = new QTextEdit( this );
+    log->setTextFormat( Qt::LogText );
+    QStyleSheetItem * item = new QStyleSheetItem( log->styleSheet(), "mytag" );
+    item->setColor( "red" );
+    item->setFontWeight( QFont::Bold );
+    item->setFontUnderline( TRUE );
+    log->append( "This is a <mytag>custom tag</mytag>!" );
+    \endcode
+    Note that only the color, bold, underline and italic attributes of
+    a QStyleSheetItem is used in LogText mode.
+
+    Note that you can use setMaxLogLines() to limit the number of
+    lines the widget can hold in LogText mode.
+
+    There are a few things that you need to be aware of when the
+    widget is in this mode:
+    \list
+    \i Functions that deal with rich text formatting and cursor
+    movement will not work or return anything valid.
+    \i Lines are equivalent to paragraphs.
+    \endlist
+
+    \section1 Using QTextEdit as an Editor
+
+    All the information about using QTextEdit as a display widget also
+    applies here.
+
+    The current format's attributes are set with setItalic(),
+    setBold(), setUnderline(), setFamily() (font family),
+    setPointSize(), setColor() and setCurrentFont(). The current
+    paragraph's alignment is set with setAlignment().
+
+    Use setSelection() to select text. The setSelectionAttributes()
+    function is used to indicate how selected text should be
+    displayed. Use hasSelectedText() to find out if any text is
+    selected. The currently selected text's position is available
+    using getSelection() and the selected text itself is returned by
+    selectedText(). The selection can be copied to the clipboard with
+    copy(), or cut to the clipboard with cut(). It can be deleted with
+    removeSelectedText(). The entire text can be selected (or
+    unselected) using selectAll(). QTextEdit supports multiple
+    selections. Most of the selection functions operate on the default
+    selection, selection 0. If the user presses a non-selecting key,
+    e.g. a cursor key without also holding down Shift, all selections
+    are cleared.
+
+    Set and get the position of the cursor with setCursorPosition()
+    and getCursorPosition() respectively. When the cursor is moved,
+    the signals currentFontChanged(), currentColorChanged() and
+    currentAlignmentChanged() are emitted to reflect the font, color
+    and alignment at the new cursor position.
+
+    If the text changes, the textChanged() signal is emitted, and if
+    the user inserts a new line by pressing Return or Enter,
+    returnPressed() is emitted. The isModified() function will return
+    TRUE if the text has been modified.
+
+    QTextEdit provides command-based undo and redo. To set the depth
+    of the command history use setUndoDepth() which defaults to 100
+    steps. To undo or redo the last operation call undo() or redo().
+    The signals undoAvailable() and redoAvailable() indicate whether
+    the undo and redo operations can be executed.
+
+    The indent() function is used to reindent a paragraph. It is
+    useful for code editors, for example in \link designer-manual.book
+    Qt Designer\endlink's code editor \e{Ctrl+I} invokes the indent()
+    function.
+
+    \section2 Editing key bindings
+
+    The list of key-bindings which are implemented for editing:
+    \table
+    \header \i Keypresses \i Action
+    \row \i Backspace \i Delete the character to the left of the cursor
+    \row \i Delete \i Delete the character to the right of the cursor
+    \row \i Ctrl+A \i Move the cursor to the beginning of the line
+    \row \i Ctrl+B \i Move the cursor one character left
+    \row \i Ctrl+C \i Copy the marked text to the clipboard (also
+		      Ctrl+Insert under Windows)
+    \row \i Ctrl+D \i Delete the character to the right of the cursor
+    \row \i Ctrl+E \i Move the cursor to the end of the line
+    \row \i Ctrl+F \i Move the cursor one character right
+    \row \i Ctrl+H \i Delete the character to the left of the cursor
+    \row \i Ctrl+K \i Delete to end of line
+    \row \i Ctrl+N \i Move the cursor one line down
+    \row \i Ctrl+P \i Move the cursor one line up
+    \row \i Ctrl+V \i Paste the clipboard text into line edit
+		      (also Shift+Insert under Windows)
+    \row \i Ctrl+X \i Cut the marked text, copy to clipboard
+		      (also Shift+Delete under Windows)
+    \row \i Ctrl+Z \i Undo the last operation
+    \row \i Ctrl+Y \i Redo the last operation
+    \row \i LeftArrow	    \i Move the cursor one character left
+    \row \i Ctrl+LeftArrow  \i Move the cursor one word left
+    \row \i RightArrow	    \i Move the cursor one character right
+    \row \i Ctrl+RightArrow \i Move the cursor one word right
+    \row \i UpArrow	    \i Move the cursor one line up
+    \row \i Ctrl+UpArrow    \i Move the cursor one word up
+    \row \i DownArrow	    \i Move the cursor one line down
+    \row \i Ctrl+Down Arrow \i Move the cursor one word down
+    \row \i PageUp	    \i Move the cursor one page up
+    \row \i PageDown	    \i Move the cursor one page down
+    \row \i Home	    \i Move the cursor to the beginning of the line
+    \row \i Ctrl+Home	    \i Move the cursor to the beginning of the text
+    \row \i End		    \i Move the cursor to the end of the line
+    \row \i Ctrl+End	    \i Move the cursor to the end of the text
+    \row \i Shift+Wheel	    \i Scroll the page horizontally
+			    (the Wheel is the mouse wheel)
+    \row \i Ctrl+Wheel	    \i Zoom the text
+    \endtable
+
+    To select (mark) text hold down the Shift key whilst pressing one
+    of the movement keystrokes, for example, \e{Shift+Right Arrow}
+    will select the character to the right, and \e{Shift+Ctrl+Right
+    Arrow} will select the word to the right, etc.
+
+    By default the text edit widget operates in insert mode so all
+    text that the user enters is inserted into the text edit and any
+    text to the right of the cursor is moved out of the way. The mode
+    can be changed to overwrite, where new text overwrites any text to
+    the right of the cursor, using setOverwriteMode().

+
+  A tag is delimited by '<' and '>'. The characters '<', '>' and '&'
+  are escaped by using '&lt;', '&gt;' and '&amp;'. Left-tags marks
+  the starting point for formatting, while right-tags mark the ending
+  point. A right-tag is the same as a left-tag, but with a '/'
+  appearing before the tag keyword.  E.g a valid left-tag: <b>, and
+  a valid right-tag: </b>.  Tags can be nested, but they have to be
+  closed in the same order as they are opened. E.g:
+  <font color=red><font color=blue>blue</font>red</font> - is valid, while:
+  <font color=red><b>bold red</font> just bold</b> - is invalid since the font tag is
+  closed before the bold tag. Note that a tag does not have to be
+  closed: '<font color=blue>Lots of text - and then some..'  is perfectly valid for
+  setting all text appearing after the tag to blue.  A tag can be used
+  to change the color of a piece of text, or set one of the following
+  formatting attributes: bold, italic and underline.  These attributes
+  are set using the <b>, <i> and <u> tags.  Example of valid tags:
+  <font color=red>, </font>, <b>, <u>, <i>, </i>.
+  Example of valid text:
+  This is some <font color=red>red text</font>, while this is some <font color=green>green
+  text</font>. <font color=blue><font color=yellow>This is yellow</font>, while this is
+  blue.</font>
+

+
+  Limitations:
+  1. A tag cannot span several lines.
+  2. Very limited error checking - mismatching left/right-tags is the

+/*!
+    \class QToolBar qtoolbar.h
+    \brief The QToolBar class provides a movable panel containing
+    widgets such as tool buttons.
+
+    \ingroup application
+    \mainclass
+
+    A toolbar is a panel that contains a set of controls, usually
+    represented by small icons. It's purpose is to provide quick
+    access to frequently used commands or options. Within a
+    QMainWindow the user can drag toolbars within and between the
+    \link QDockArea dock areas\endlink. Toolbars can also be dragged
+    out of any dock area to float freely as top-level windows.
+
+    QToolBar is a specialization of QDockWindow, and so provides all
+    the functionality of a QDockWindow.
+
+    To use QToolBar you simply create a QToolBar as a child of a
+    QMainWindow, create a number of QToolButton widgets (or other
+    widgets) in left to right (or top to bottom) order and call
+    addSeparator() when you want a separator. When a toolbar is
+    floated the caption used is the label given in the constructor
+    call. This can be changed with setLabel().
+
+    \quotefile action/application.cpp
+    \skipto new QToolBar
+    \printuntil fileSaveAction
+
+    This extract from the \l application/application.cpp example shows
+    the creation of a new toolbar as a child of a QMainWindow and
+    adding two QActions.
+
+    You may use most widgets within a toolbar, with QToolButton and
+    QComboBox being the most common.
+
+    If you create a new widget on an already visible QToolBar, this
+    widget will automatically become visible without needing a show()
+    call. (This differs from every other Qt widget container. We
+    recommend calling show() anyway since we hope to fix this anomaly
+    in a future release.)
+
+    QToolBars, like QDockWindows, are located in \l{QDockArea}s or
+    float as top-level windows. QMainWindow provides four QDockAreas
+    (top, left, right and bottom). When you create a new toolbar (as
+    in the example above) as a child of a QMainWindow the toolbar will
+    be added to the top dock area. You can move it to another dock
+    area (or float it) by calling QMainWindow::moveDockWindow(). QDock
+    areas lay out their windows in \link qdockarea.html#lines
+    Lines\endlink.
+
+    If the main window is resized so that the area occupied by the
+    toolbar is too small to show all its widgets a little arrow button
+    (which looks like a right-pointing chevron, '&#187;') will appear
+    at the right or bottom of the toolbar depending on its
+    orientation. Clicking this button pops up a menu that shows the
+    'overflowing' items. QToolButtons are represented in the menu using
+    their textLabel property, other QButton subclasses are represented
+    using their text property, and QComboBoxes are represented as submenus,
+    with the caption text being used in the submenu item.
+
+    Usually a toolbar will get precisely the space it needs. However,
+    with setHorizontalStretchable(), setVerticalStretchable() or
+    setStretchableWidget() you can tell the main window to expand the
+    toolbar to fill all available space in the specified orientation.
+
+    The toolbar arranges its buttons either horizontally or vertically
+    (see orientation() for details). Generally, QDockArea will set the
+    orientation correctly for you, but you can set it yourself with
+    setOrientation() and track any changes by connecting to the
+    orientationChanged() signal.
+
+    You can use the clear() method to remove all items from a toolbar.

+
+1.  Tool Bars should contain only high-frequency functions.  Avoid putting
+things like About and Exit on a tool bar unless they are frequent functions.
+
+2.  All tool bar buttons must have some keyboard access method (it can be a
+menu or shortcut key or a function in a dialog box that can be accessed
+through the keyboard).
+
+3.  Make tool bar functions as efficient as possible (the common example is to
+Print in Microsoft applications, it doesn't bring up the Print dialog box, it
+prints immediately to the default printer).
+
+4.  Avoid turning tool bars into graphical menu bars.  To me, a tool bar should
+be efficient. Once you make almost all the items in a tool bar into graphical
+pull-down menus, you start to lose efficiency.
+
+5.  Make sure that adjacent icons are distinctive. There are some tool bars
+where you see a group of 4-5 icons that represent related functions, but they
+are so similar that you can't differentiate among them.	 These tool bars are
+often a poor attempt at a "common visual language".
+
+6.  Use any de facto standard icons of your platform (for windows use the
+cut, copy and paste icons provided in dev kits rather than designing your
+own).
+
+7.  Avoid putting a highly destructive tool bar button (delete database) by a
+safe, high-frequency button (Find) -- this will yield 1-0ff errors).
+
+8.  Tooltips in many Microsoft products simply reiterate the menu text even
+when that is not explanatory.  Consider making your tooltips slightly more
+verbose and explanatory than the corresponding menu item.
+
+9.  Keep the tool bar as stable as possible when you click on different
+objects. Consider disabling tool bar buttons if they are used in most, but not
+all contexts.
+
+10.  If you have multiple tool bars (like the Microsoft MMC snap-ins have),
+put the most stable tool bar to at the left with less stable ones to the
+right. This arrangement (stable to less stable) makes the tool bar somewhat
+more predictable.
+
+11.  Keep a single tool bar to fewer than 20 items divided into 4-7 groups of
+items.

+
+    \brief The QToolBox class provides a column of tabbed widget
+    items.
+
+    \mainclass
+    \ingroup advanced
+
+    A toolbox is a widget that displays a column of tabs one above the
+    other, with the current item displayed below the current tab.
+    Every tab has an index position within the column of tabs. A tab's
+    item is a QWidget.
+
+    Each item has an itemLabel(), an optional icon, itemIconSet(), an
+    optional itemToolTip(), and a \link item() widget\endlink. The
+    item's attributes can be changed with setItemLabel(),
+    setItemIconSet() and setItemToolTip().
+
+    Items are added using addItem(), or inserted at particular
+    positions using insertItem(). The total number of items is given
+    by count(). Items can be deleted with delete, or removed from the
+    toolbox with removeItem(). Combining removeItem() and insertItem()
+    allows to move items to different positions.
+
+    The current item widget is returned by currentItem() and set with
+    setCurrentItem(). If you prefer you can work in terms of indexes
+    using currentIndex(), setCurrentIndex(), indexOf() and item().
+
+    The currentChanged() signal is emitted when the current item is
+    changed.

+    \class QToolButton qtoolbutton.h
+    \brief The QToolButton class provides a quick-access button to
+    commands or options, usually used inside a QToolBar.
+
+    \ingroup basic
+    \mainclass
+
+    A tool button is a special button that provides quick-access to
+    specific commands or options. As opposed to a normal command
+    button, a tool button usually doesn't show a text label, but shows
+    an icon instead. Its classic usage is to select tools, for example
+    the "pen" tool in a drawing program. This would be implemented
+    with a QToolButton as toggle button (see setToggleButton() ).
+
+    QToolButton supports auto-raising. In auto-raise mode, the button
+    draws a 3D frame only when the mouse points at it. The feature is
+    automatically turned on when a button is used inside a QToolBar.
+    Change it with setAutoRaise().
+
+    A tool button's icon is set as QIconSet. This makes it possible to
+    specify different pixmaps for the disabled and active state. The
+    disabled pixmap is used when the button's functionality is not
+    available. The active pixmap is displayed when the button is
+    auto-raised because the mouse pointer is hovering over it.
+
+    The button's look and dimension is adjustable with
+    setUsesBigPixmap() and setUsesTextLabel(). When used inside a
+    QToolBar in a QMainWindow, the button automatically adjusts to
+    QMainWindow's settings (see QMainWindow::setUsesTextLabel() and
+    QMainWindow::setUsesBigPixmaps()). The pixmap set on a QToolButton
+    will be set to 22x22 if it is bigger than this size. If
+    usesBigPixmap() is TRUE, then the pixmap will be set to 32x32.
+
+    A tool button can offer additional choices in a popup menu. The
+    feature is sometimes used with the "Back" button in a web browser.
+    After pressing and holding the button down for a while, a menu
+    pops up showing a list of possible pages to jump to. With
+    QToolButton you can set a popup menu using setPopup(). The default
+    delay is 600ms; you can adjust it with setPopupDelay().

+    \class QToolTip qtooltip.h
+    \brief The QToolTip class provides tool tips (balloon help) for
+    any widget or rectangular part of a widget.
+
+    \ingroup helpsystem
+    \mainclass
+
+    The tip is a short, single line of text reminding the user of the
+    widget's or rectangle's function. It is drawn immediately below
+    the region in a distinctive black-on-yellow combination.
+
+    The tip can be any Rich-Text formatted string.
+
+    QToolTipGroup provides a way for tool tips to display another text
+    elsewhere (most often in a \link QStatusBar status bar\endlink).
+
+    At any point in time, QToolTip is either dormant or active. In
+    dormant mode the tips are not shown and in active mode they are.
+    The mode is global, not particular to any one widget.
+
+    QToolTip switches from dormant to active mode when the user hovers
+    the mouse on a tip-equipped region for a second or so and remains
+    active until the user either clicks a mouse button, presses a key,
+    lets the mouse hover for five seconds or moves the mouse outside
+    \e all tip-equipped regions for at least a second.
+
+    The QToolTip class can be used in three different ways:
+    \list 1
+    \i Adding a tip to an entire widget.
+    \i Adding a tip to a fixed rectangle within a widget.
+    \i Adding a tip to a dynamic rectangle within a widget.
+    \endlist
+
+    To add a tip to a widget, call the \e static function
+    QToolTip::add() with the widget and tip as arguments:
+
+    \code
+	QToolTip::add( quitButton, "Leave the application" );
+    \endcode
+
+    This is the simplest and most common use of QToolTip. The tip
+    will be deleted automatically when \e quitButton is deleted, but
+    you can remove it yourself, too:
+
+    \code
+	QToolTip::remove( quitButton );
+    \endcode
+
+    You can also display another text (typically in a \link QStatusBar
+    status bar),\endlink courtesy of \l{QToolTipGroup}. This example
+    assumes that \e grp is a \c{QToolTipGroup *} and is already
+    connected to the appropriate status bar:
+
+    \code
+	QToolTip::add( quitButton, "Leave the application", grp,
+		       "Leave the application, prompting to save if necessary" );
+	QToolTip::add( closeButton, "Close this window", grp,
+		       "Close this window, prompting to save if necessary" );
+    \endcode
+
+    To add a tip to a fixed rectangle within a widget, call the static
+    function QToolTip::add() with the widget, rectangle and tip as
+    arguments. (See the \c tooltip/tooltip.cpp example.) Again, you
+    can supply a \c{QToolTipGroup *} and another text if you want.
+
+    Both of these are one-liners and cover the majority of cases. The
+    third and most general way to use QToolTip requires you to
+    reimplement a pure virtual function to decide whether to pop up a
+    tool tip. The \c tooltip/tooltip.cpp example demonstrates this
+    too. This mode can be used to implement tips for text that can
+    move as the user scrolls, for example.
+
+    To use QToolTip like this, you must subclass QToolTip and
+    reimplement maybeTip(). QToolTip calls maybeTip() when a tip
+    should pop up, and maybeTip() decides whether to show a tip.
+
+    Tool tips can be globally disabled using
+    QToolTip::setGloballyEnabled() or disabled in groups with
+    QToolTipGroup::setEnabled().
+
+    You can retrieve the text of a tooltip for a given position within
+    a widget using textFor().
+
+    The global tooltip font and palette can be set with the static
+    setFont() and setPalette() functions respectively.

+/*!
+    \class QValidator
+    \brief The QValidator class provides validation of input text.
+
+    \ingroup misc
+    \mainclass
+
+    The class itself is abstract. Two subclasses, \l QIntValidator and
+    \l QDoubleValidator, provide basic numeric-range checking, and \l
+    QRegExpValidator provides general checking using a custom regular
+    expression.
+
+    If the built-in validators aren't sufficient, you can subclass
+    QValidator. The class has two virtual functions: validate() and
+    fixup().
+
+    \l validate() must be implemented by every subclass. It returns
+    \c Invalid, \c Intermediate or \c Acceptable depending on whether
+    its argument is valid (for the subclass's definition of valid).
+
+    These three states require some explanation. An \c Invalid string
+    is \e clearly invalid. \c Intermediate is less obvious: the
+    concept of validity is slippery when the string is incomplete
+    (still being edited). QValidator defines \c Intermediate as the
+    property of a string that is neither clearly invalid nor
+    acceptable as a final result. \c Acceptable means that the string
+    is acceptable as a final result. One might say that any string
+    that is a plausible intermediate state during entry of an \c
+    Acceptable string is \c Intermediate.
+
+    Here are some examples:
+
+    \list
+
+    \i For a line edit that accepts integers from 0 to 999 inclusive,
+    42 and 123 are \c Acceptable, the empty string and 1114 are \c
+    Intermediate and asdf is \c Invalid.
+
+    \i For an editable combobox that accepts URLs, any well-formed URL
+    is \c Acceptable, "http://www.trolltech.com/," is \c Intermediate
+    (it might be a cut and paste operation that accidentally took in a
+    comma at the end), the empty string is \c Intermediate (the user
+    might select and delete all of the text in preparation for entering
+    a new URL), and "http:///./" is \c Invalid.
+
+    \i For a spin box that accepts lengths, "11cm" and "1in" are \c
+    Acceptable, "11" and the empty string are \c Intermediate and
+    "http://www.trolltech.com" and "hour" are \c Invalid.
+
+    \endlist
+
+    \l fixup() is provided for validators that can repair some user
+    errors. The default implementation does nothing. QLineEdit, for
+    example, will call fixup() if the user presses Enter (or Return)
+    and the content is not currently valid. This allows the fixup()
+    function the opportunity of performing some magic to make an \c
+    Invalid string \c Acceptable.
+
+    QValidator is typically used with QLineEdit, QSpinBox and
+    QComboBox.
+*/
+
+
+/*!
+    \enum QValidator::State
+
+    This enum type defines the states in which a validated string can
+    exist.
+
+    \value Invalid  the string is \e clearly invalid.

+
+    Reimplementations of this function can change \a input even if
+    they do not produce a valid string. For example, an ISBN validator
+    might want to delete every character except digits and "-", even
+    if the result is still not a valid ISBN; a surname validator might

+/*!
+    \class QWhatsThis qwhatsthis.h
+    \brief The QWhatsThis class provides a simple description of any
+    widget, i.e. answering the question "What's this?".
+
+    \ingroup helpsystem
+    \mainclass
+
+    "What's this?" help is part of an application's online help system
+    that provides users with information about functionality, usage,
+    background etc., in various levels of detail from short tool tips
+    to full text browsing help windows.
+
+    QWhatsThis provides a single window with an explanatory text that
+    pops up when the user asks "What's this?". The default way to do
+    this is to focus the relevant widget and press Shift+F1. The help
+    text appears immediately; it goes away as soon as the user does
+    something else.
+
+    (Note that if there is an accelerator for Shift+F1, this mechanism
+    will not work.)
+
+    To add "What's this?" text to a widget you simply call
+    QWhatsThis::add() for the widget. For example, to assign text to a
+    menu item, call QMenuData::setWhatsThis(); for a global
+    accelerator key, call QAccel::setWhatsThis() and If you're using
+    actions, use QAction::setWhatsThis().
+
+    The text can be either rich text or plain text. If you specify a
+    rich text formatted string, it will be rendered using the default
+    stylesheet. This makes it possible to embed images. See
+    QStyleSheet::defaultSheet() for details.
+
+    \quotefile action/application.cpp
+    \skipto fileOpenText
+    \printuntil setWhatsThis
+
+    An alternative way to enter "What's this?" mode is to use the
+    ready-made tool bar tool button from
+    QWhatsThis::whatsThisButton(). By invoking this context help
+    button (in the picture below the first one from the right) the
+    user switches into "What's this?" mode. If they now click on a
+    widget the appropriate help text is shown. The mode is left when
+    help is given or when the user presses Esc.
+
+    \img whatsthis.png
+
+    If you are using QMainWindow you can also use the
+    QMainWindow::whatsThis() slot to invoke the mode from a menu item.
+
+    For more control you can create a dedicated QWhatsThis object for
+    a special widget. By subclassing and reimplementing
+    QWhatsThis::text() it is possible to have different help texts,
+    depending on the position of the mouse click. By reimplementing
+    QWhatsThis::clicked() it is possible to have hyperlinks inside the
+    help texts.
+
+    If you wish to control the "What's this?" behavior of a widget
+    manually see QWidget::customWhatsThis().
+
+    The What's This object can be removed using QWhatsThis::remove(),
+    although this is rarely necessary because it is automatically
+    removed when the widget is destroyed.

+    \class QWidgetPlugin qwidgetplugin.h
+    \brief The QWidgetPlugin class provides an abstract base for custom QWidget plugins.
+
+    \ingroup plugins
+
+    The widget plugin is a simple plugin interface that makes it easy
+    to create custom widgets that can be included in forms using \link
+    designer-manual.book Qt Designer\endlink and used by applications.
+
+    Writing a widget plugin is achieved by subclassing this base
+    class, reimplementing the pure virtual functions keys(), create(),
+    group(), iconSet(), includeFile(), toolTip(), whatsThis() and
+    isContainer(), and exporting the class with the \c Q_EXPORT_PLUGIN
+    macro.
+

+    \brief The QWidgetContainerPlugin class provides an abstract base
+    for complex custom container QWidget plugins.
+
+    \internal
+
+    \ingroup plugins
+
+    The widget container plugin is a subclass of QWidgetPlugin and
+    extends the interface with functions necessary for supporting
+    complex container widgets via plugins. These container widgets are
+    widgets that have one or multiple sub widgets which act as the
+    widget's containers. If the widget has multiple container
+    subwidgets, they are referred to as "pages", and only one can be
+    active at a time. Examples of complex container widgets include:
+    QTabWidget, QWidgetStack and QToolBox.
+
+    Writing a complex container widget plugin is achieved by
+    subclassing this base class. First by reimplementing
+    QWidgetPlugin's pure virtual functions keys(), create(), group(),
+    iconSet(), includeFile(), toolTip(), whatsThis() and
+    isContainer(), and exporting the class with the \c Q_EXPORT_PLUGIN
+    macro. In addition containerOfWidget(), isPassiveInteractor() and
+    supportsPages() must be reimplemented. If the widget
+    supportsPages(), count(), currentIndex(), pageLabel(), page(),
+    pages() and createCode() must be implemented. If the widget
+    supportsPages() and you want to allow the containers pages to be
+    modified, you must also reimplement addPage(), insertPage(),
+    removePage(), movePage() and renamePage().

+/*!
+    \class QWidgetStack
+    \brief The QWidgetStack class provides a stack of widgets of which
+    only the top widget is user-visible.
+
+    \ingroup organizers
+    \mainclass
+
+    The application programmer can move any widget to the top of the
+    stack at any time using raiseWidget(), and add or remove widgets
+    using addWidget() and removeWidget(). It is not sufficient to pass
+    the widget stack as parent to a widget which should be inserted into
+    the widgetstack.
+
+    visibleWidget() is the \e get equivalent of raiseWidget(); it
+    returns a pointer to the widget that is currently at the top of
+    the stack.
+
+    QWidgetStack also provides the ability to manipulate widgets
+    through application-specified integer IDs. You can also translate
+    from widget pointers to IDs using id() and from IDs to widget
+    pointers using widget(). These numeric IDs are unique (per
+    QWidgetStack, not globally), but QWidgetStack does not attach any
+    additional meaning to them.
+
+    The default widget stack is frameless, but you can use the usual
+    QFrame functions (such as setFrameStyle()) to add a frame.
+
+    QWidgetStack provides a signal, aboutToShow(), which is emitted
+    just before a managed widget is shown.
