+    \class TQListViewItem
+    \brief The TQListViewItem class implements a list view item.
+
+    \ingroup advanced
+
+    A list view item is a multi-column object capable of displaying
+    itself in a TQListView.
+
+    The easiest way to use TQListViewItem is to construct one with a
+    few constant strings, and either a TQListView or another
+    TQListViewItem as parent.
+    \code
+	(void) new TQListViewItem( listView, "Column 1", "Column 2" );
+	(void) new TQListViewItem( 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, TQListView sorts its
+    items; this can be switched off with TQListView::setSorting(-1).
+
+    The parent must be another TQListViewItem or a TQListView. If the
+    parent is a TQListView, the item becomes a top-level item within
+    that TQListView. If the parent is another TQListViewItem, 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 TQListViewItem in a TQListView using
+    TQListView::selectedItem(), TQListView::currentItem(),
+    TQListView::firstChild(), TQListView::lastItem() and
+    TQListView::findItem().
+
+    If you call \c delete on a list view item, it will be deleted as
+    expected, and as usual for \l{TQObject}s, if it has any child items
+    (to any depth), all these will be deleted too.
+
+    \l{TQCheckListItem}s are list view items that have a checkbox or
+    radio button and can be used in place of plain TQListViewItems.
+
+    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
+	TQListViewItem * 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
+	TQListViewItemIterator it( listview );
+	while ( it.current() ) {
+	    TQListViewItem *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; TQListView will
+    always call it before it needs to show an item.
+
+    Many programs will need to reimplement TQListViewItem. 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, TQFileDialog
+	    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 tquickly: The files and subdirectories in a
+    directory aren't inserted into the tree until they're actually
+    needed.

+
+    \value Multi  When the user selects an item in the usual way, the

+    \class TQListView
+    \brief The TQListView class implements a list/tree view.
+
+    \ingroup advanced
+    \mainclass
+
+    It can display and control a hierarchy of multi-column items, and
+    provides the ability to add new items at any time. The user may
+    select one or many items (depending on the \c SelectionMode) and
+    sort the list in increasing or decreasing order by any column.
+
+    The simplest pattern of use is to create a TQListView, add some
+    column headers using addColumn() and create one or more
+    TQListViewItem or TQCheckListItem objects with the TQListView as
+    parent:
+
+    \quotefile xml/tagreader-with-features/structureparser.h
+    \skipto TQListView * table
+    \printline
+    \quotefile xml/tagreader-with-features/structureparser.cpp
+    \skipto addColumn
+    \printline addColumn
+    \printline
+    \skipto new TQListViewItem( table
+    \printline
+
+    Further nodes can be added to the list view object (the root of the
+    tree) or as child nodes to TQListViewItems:
+
+    \skipto for ( int i = 0 ; i < attributes.length();
+    \printuntil }
+
+    (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 TQScrollView functions:
+    \link TQScrollView::contentsMousePressEvent() contentsMousePressEvent\endlink,
+    \link TQScrollView::contentsMouseReleaseEvent() contentsMouseReleaseEvent\endlink,
+    \link TQScrollView::contentsMouseDoubleClickEvent() contentsMouseDoubleClickEvent\endlink,
+    \link TQScrollView::contentsMouseMoveEvent() contentsMouseMoveEvent\endlink,
+    \link TQScrollView::contentsDragEnterEvent() contentsDragEnterEvent\endlink,
+    \link TQScrollView::contentsDragMoveEvent() contentsDragMoveEvent\endlink,
+    \link TQScrollView::contentsDragLeaveEvent() contentsDragLeaveEvent\endlink,
+    \link TQScrollView::contentsDropEvent() contentsDropEvent\endlink, and
+    \link TQScrollView::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
+    TQListViewItem::itemBelow(); over a list view's top-level items
+    using TQListViewItem::firstChild() and
+    TQListViewItem::nextSibling(); or every item using a
+    TQListViewItemIterator. See
+    the TQListViewItem documentation for examples of traversal.
+
+    An item can be moved amongst its siblings using
+    TQListViewItem::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
+    TQListView::SelectionMode documentation. The default is \c Single
+    selection, which you can change using setSelectionMode().
+
+    Because TQListView 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()).
+
+    TQListView 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(TQListViewItem*) (applicable only to a
+    \c Single selection list view), and currentChanged(TQListViewItem*).
+    The second group consists of doubleClicked(TQListViewItem*),
+    returnPressed(TQListViewItem*),
+    rightButtonClicked(TQListViewItem*, const TQPoint&, 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 TQTimer::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, TQListView 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 TQListView::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 TQListViewItemIterator
+    \brief The TQListViewItemIterator class provides an iterator for collections of TQListViewItems.
+
+    \ingroup advanced
+
+    Construct an instance of a TQListViewItemIterator, with either a
+    TQListView* or a TQListViewItem* as argument, to operate on the tree
+    of TQListViewItems, starting from the argument.
+
+    A TQListViewItemIterator 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
+    TQPtrList:
+    \code
+    TQPtrList<TQListViewItem> lst;
+    TQListViewItemIterator 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
+    TQPtrList<TQListViewItem> lst;
+    TQListViewItemIterator it( myListView, TQListViewItemIterator::Selected );
+    while ( it.current() ) {
+	lst.append( it.current() );
+	++it;
+    }
+    \endcode
+
+    A TQListViewItemIterator provides a convenient and easy way to
+    traverse a hierarchical TQListView.
+
+    Multiple TQListViewItemIterators can operate on the tree of
+    TQListViewItems. A TQListView knows about all iterators operating on
+    its TQListViewItems. So when a TQListViewItem 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.
