+
+
+The TQPopupMenu class provides a popup menu widget.
+<p>
+
+
+<p> 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
+<a href="qmenudata.html#insertItem">TQMenuBar::insertItem</a>() to insert a popup menu into a menu bar.
+Show a context menu either asynchronously with <a href="#popup">popup</a>() or
+synchronously with <a href="#exec">exec</a>().
+<p> Technically, a popup menu consists of a list of menu items. You
+add items with <a href="qmenudata.html#insertItem">insertItem</a>(). An item is either a string, a pixmap
+or a custom item that provides its own drawing function (see
+<a href="qcustommenuitem.html">TQCustomMenuItem</a>). In addition, items can have an optional icon
+drawn on the very left side and an accelerator key such as
+"Ctrl+X".
+<p> 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 <a href="qmenudata.html#insertSeparator">insertSeparator</a>(). For submenus, you pass a
+pointer to a TQPopupMenu in your call to insertItem(). All other
+items are considered action items.
+<p> When inserting action items you usually specify a receiver and a
+slot. The receiver will be notifed whenever the item is selected.
+In addition, TQPopupMenu provides two signals, <a href="#activated">activated</a>() and
+<a href="#highlighted">highlighted</a>(), 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 <a href="qmenudata.html#setItemParameter">setItemParameter</a>() to associate a unique
+value with each item.
+<p> You clear a popup menu with <a href="qmenudata.html#clear">clear</a>() and remove single items with
+<a href="qmenudata.html#removeItem">removeItem</a>() or <a href="qmenudata.html#removeItemAt">removeItemAt</a>().
+<p> A popup menu can display check marks for certain items when
+enabled with <a href="#setCheckable">setCheckable</a>(TRUE). You check or uncheck items with
+<a href="qmenudata.html#setItemChecked">setItemChecked</a>().
+<p> Items are either enabled or disabled. You toggle their state with
+<a href="qmenudata.html#setItemEnabled">setItemEnabled</a>(). Just before a popup menu becomes visible, it
+emits the <a href="#aboutToShow">aboutToShow</a>() signal. You can use this signal to set the
+correct enabled/disabled states of all menu items before the user
+sees it. The corresponding <a href="#aboutToHide">aboutToHide</a>() signal is emitted when
+the menu hides again.
+<p> You can provide What's This? help for single menu items with
+<a href="qmenudata.html#setWhatsThis">setWhatsThis</a>(). See <a href="qwhatsthis.html">TQWhatsThis</a> for general information about this
+kind of lightweight online help.
+<p> For ultimate flexibility, you can also add entire widgets as items
+into a popup menu (for example, a color selector).
+<p> A TQPopupMenu 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 <a href="#insertTearOffHandle">insertTearOffHandle</a>(). 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 <a href="qtoolbar.html">TQToolBar</a>
+instead. Tear-off menus cannot contain custom widgets; if the
+original menu contains a custom widget item, this item is omitted.
+<p> <a href="menu-example.html">menu/menu.cpp</a> is an example of
+<a href="qmenubar.html">TQMenuBar</a> and TQPopupMenu use.

+<hr><h2>Member Function Documentation</h2>
+<h3 class=fn><a name="TQPopupMenu"></a>TQPopupMenu::TQPopupMenu ( <a href="qwidget.html">TQWidget</a>&nbsp;*&nbsp;parent = 0, const&nbsp;char&nbsp;*&nbsp;name = 0 )
+</h3>
+Constructs a popup menu called <em>name</em> with parent <em>parent</em>.
+<p> Although a popup menu is always a top-level widget, if a parent is
+passed the popup menu will be deleted when that parent is
+destroyed (as with any other <a href="qobject.html">TQObject</a>).
+
+<h3 class=fn><a name="~TQPopupMenu"></a>TQPopupMenu::~TQPopupMenu ()
+</h3>
+Destroys the popup menu.
+
+<h3 class=fn>void <a name="aboutToHide"></a>TQPopupMenu::aboutToHide ()<tt> [signal]</tt>
+</h3>
+
+<p> This signal is emitted just before the popup menu is hidden after
+it has been displayed.
+<p> <b>Warning:</b> Do not open a widget in a slot connected to this signal.
+<p> <p>See also <a href="#aboutToShow">aboutToShow</a>(), <a href="qmenudata.html#setItemEnabled">setItemEnabled</a>(), <a href="qmenudata.html#setItemChecked">setItemChecked</a>(), <a href="qmenudata.html#insertItem">insertItem</a>(), and <a href="qmenudata.html#removeItem">removeItem</a>().
+
+<h3 class=fn>void <a name="aboutToShow"></a>TQPopupMenu::aboutToShow ()<tt> [signal]</tt>
+</h3>
+
+<p> This signal is emitted just before the popup menu is displayed.
+You can connect it to any slot that sets up the menu contents
+(e.g. to ensure that the right items are enabled).
+<p> <p>See also <a href="#aboutToHide">aboutToHide</a>(), <a href="qmenudata.html#setItemEnabled">setItemEnabled</a>(), <a href="qmenudata.html#setItemChecked">setItemChecked</a>(), <a href="qmenudata.html#insertItem">insertItem</a>(), and <a href="qmenudata.html#removeItem">removeItem</a>().
+
+<p>Example: <a href="mdi-example.html#x2048">mdi/application.cpp</a>.
+<h3 class=fn><a href="qkeysequence.html">TQKeySequence</a> <a name="accel"></a>TQMenuData::accel ( int&nbsp;id ) const
+</h3>
+Returns the accelerator key that has been defined for the menu
+item <em>id</em>, or 0 if it has no accelerator key or if there is no
+such menu item.
+<p> <p>See also <a href="qmenudata.html#setAccel">setAccel</a>(), <a href="qaccel.html">TQAccel</a>, and <a href="qnamespace-h.html">qnamespace.h</a>.
+
+<h3 class=fn>void <a name="activated"></a>TQPopupMenu::activated ( int&nbsp;id )<tt> [signal]</tt>
+</h3>
+
+<p> This signal is emitted when a menu item is selected; <em>id</em> is the
+id of the selected item.
+<p> Normally, you connect each menu item to a single slot using
+<a href="qmenudata.html#insertItem">TQMenuData::insertItem</a>(), but sometimes you will want to connect
+several items to a single slot (most often if the user selects
+from an array). This signal is useful in such cases.
+<p> <p>See also <a href="#highlighted">highlighted</a>() and <a href="qmenudata.html#insertItem">TQMenuData::insertItem</a>().
+
+<p>Examples: <a href="grapher-nsplugin-example.html#x2767">grapher/grapher.cpp</a>, <a href="helpviewer-example.html#x1004">helpviewer/helpwindow.cpp</a>, <a href="qdir-example.html#x1835">qdir/qdir.cpp</a>, <a href="qwerty-example.html#x386">qwerty/qwerty.cpp</a>, <a href="scrollview-example.html#x642">scrollview/scrollview.cpp</a>, and <a href="showimg-example.html#x1341">showimg/showimg.cpp</a>.

+
+or aligned to a widget:

+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+<p> Executes this popup synchronously.
+<p> Opens the popup menu so that the item number <em>indexAtPoint</em> will
+be at the specified <em>global</em> position <em>pos</em>. To translate a
+widget's local coordinates into global coordinates, use
+<a href="qwidget.html#mapToGlobal">TQWidget::mapToGlobal</a>().
+<p> 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).
+<p> Note that all signals are emitted as usual. If you connect a menu
+item to a slot and call the menu's <a href="#exec">exec</a>(), you get the result both
+via the signal-slot connection and in the return value of exec().
+<p> Common usage is to position the popup at the current mouse
+position:
+<pre>
+ <a href="#exec">exec</a>( TQCursor::<a href="qcursor.html#pos">pos</a>() );
+ </pre>
+
+or aligned to a widget:
+<pre>
+ <a href="#exec">exec</a>( somewidget.mapToGlobal(TQPoint(0, 0)) );
+ </pre>
+
+<p> When positioning a popup with exec() or <a href="#popup">popup</a>(), bear in mind that
+you cannot rely on the popup menu's current <a href="qwidget.html#size">size</a>(). 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 <a href="qwidget.html#sizeHint">sizeHint</a>(). It calculates the proper size

+</h3>
+The family of <a href="qmenudata.html#insertItem">insertItem</a>() functions inserts menu items into a
+popup menu or a menu bar.
+<p> 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 <a href="qcustommenuitem.html">TQCustomMenuItem</a>) or
+even widgets into popup menus.
+<p> 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.
+<p> The number of insert functions may look confusing, but they are
+actually tquite simple to use.
+<p> This default version inserts a menu item with the text <em>text</em>,
+the accelerator key <em>accel</em>, an id and an optional index and
+connects it to the slot <em>member</em> in the object <em>receiver</em>.
+<p> Example:
+<pre>
+ <a href="qmenubar.html">TQMenuBar</a> *mainMenu = new <a href="qmenubar.html">TQMenuBar</a>;
+ TQPopupMenu *fileMenu = new TQPopupMenu;
+ fileMenu-&gt;<a href="qmenudata.html#insertItem">insertItem</a>( "New", myView, SLOT(newFile()), CTRL+Key_N );
+ fileMenu-&gt;<a href="qmenudata.html#insertItem">insertItem</a>( "Open", myView, SLOT(open()), CTRL+Key_O );
+ mainMenu-&gt;<a href="qmenudata.html#insertItem">insertItem</a>( "File", fileMenu );
+ </pre>
+
+<p> Not all insert functions take an object/slot parameter or an
+accelerator key. Use <a href="qmenudata.html#connectItem">connectItem</a>() and <a href="qmenudata.html#setAccel">setAccel</a>() on those items.
+<p> If you need to translate accelerators, use <a href="qobject.html#tr">tr</a>() with the text and
+accelerator. (For translations use a string <a href="qkeysequence.html">key
+ sequence</a>.):
+<pre>
+ fileMenu-&gt;insertItem( <a href="qobject.html#tr">tr</a>("Open"), myView, SLOT(open()),
+ <a href="qobject.html#tr">tr</a>("Ctrl+O") );
+ </pre>
+
+<p> In the example above, pressing Ctrl+O or selecting "Open" from the
+menu activates the myView->open() function.
+<p> Some insert functions take a <a href="qiconset.html">TQIconSet</a> parameter to specify the
+little menu item icon. Note that you can always pass a <a href="qpixmap.html">TQPixmap</a>
+object instead.
+<p> The <em>id</em> specifies the identification number associated with the
+menu item. Note that only positive values are valid, as a negative
+value will make TQt select a unique id for the item.
+<p> The <em>index</em> specifies the position in the menu. The menu item is
+appended at the end of the list if <em>index</em> is negative.
+<p> Note that keyboard accelerators in TQt are not application-global,
+instead they are bound to a certain top-level window. For example,
+accelerators in TQPopupMenu 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 <a href="qwidget.html#parentWidget">parentWidget</a>()
+chain. The menu will then install its accelerator object on that
+top-level widget. For all other cases use an independent <a href="qaccel.html">TQAccel</a>
+object.
+<p> <b>Warning:</b> Be careful when passing a literal 0 to <a href="qmenudata.html#insertItem">insertItem</a>()
+because some C++ compilers choose the wrong overloaded function.
+Cast the 0 to what you mean, e.g. <tt>(TQObject*)0</tt>.
+<p> <b>Warning:</b> 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 TQt
+version.

+<p> Ownership of <em>widget</em> is transferred to the popup menu or to the

+<p> Theoretically, any widget can be inserted into a popup menu. In
+practice, this only makes sense with certain widgets.
+<p> If a widget is not focus-enabled (see
+<a href="qwidget.html#isFocusEnabled">TQWidget::isFocusEnabled</a>()), the menu treats it as a separator;
+this means that the item is not selectable and will never get
+focus. In this way you can, for example, simply insert a <a href="qlabel.html">TQLabel</a> if
+you need a popup menu with a title.
+<p> If the widget is focus-enabled it will get focus when the user
+traverses the popup menu with the arrow keys. If the widget does
+not accept <tt>ArrowUp</tt> and <tt>ArrowDown</tt> in its key event handler,
+the focus will move back to the menu when the respective arrow key
+is hit one more time. This works with a <a href="qlineedit.html">TQLineEdit</a>, for example. If
+the widget accepts the arrow key itself, it must also provide the
+possibility to put the focus back on the menu again by calling
+<a href="qwidget.html#focusNextPrevChild">TQWidget::focusNextPrevChild</a>(). Futhermore, if the embedded widget
+closes the menu when the user made a selection, this can be done
+safely by calling:
+<pre>

+Inserts a separator at position <em>index</em>, and returns the <a href="qmenudata.html#menu-identifier">menu identifier</a>
+number allocated to it. The separator becomes the last menu item if
+<em>index</em> is negative.
+<p> In a popup menu a separator is rendered as a horizontal line. In a
+<a href="motif-extension.html#Motif">Motif</a> menu bar a separator is spacing, so the rest of the items
+(normally just "Help") are drawn right-justified. In a Windows
+menu bar separators are ignored (to comply with the Windows style
+guidelines).

+<h3 class=fn>int <a name="insertTearOffHandle"></a>TQPopupMenu::insertTearOffHandle ( int&nbsp;id = -1, int&nbsp;index = -1 )
+</h3>
+Inserts a tear-off handle into the menu. A tear-off handle is a
+special menu item that creates a copy of the menu when the menu is
+selected. This "torn-off" copy lives in a separate window. It
+contains the same menu items as the original menu, with the
+exception of the tear-off handle.
+<p> The handle item is assigned the identifier <em>id</em> or an
+automatically generated identifier if <em>id</em> is < 0. The generated
+identifiers (negative integers) are guaranteed to be unique within
+the entire application.
+<p> The <em>index</em> specifies the position in the menu. The tear-off
+handle is appended at the end of the list if <em>index</em> is negative.

+<h3 class=fn>void <a name="popup"></a>TQPopupMenu::popup ( const&nbsp;<a href="qpoint.html">TQPoint</a>&nbsp;&amp;&nbsp;pos, int&nbsp;indexAtPoint = -1 )

+Displays the popup menu so that the item number <em>indexAtPoint</em>
+will be at the specified <em>global</em> position <em>pos</em>. To translate a
+widget's local coordinates into global coordinates, use
+<a href="qwidget.html#mapToGlobal">TQWidget::mapToGlobal</a>().
+<p> When positioning a popup with <a href="#exec">exec</a>() or <a href="#popup">popup</a>(), bear in mind that
+you cannot rely on the popup menu's current <a href="qwidget.html#size">size</a>(). 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 <a href="qwidget.html#sizeHint">sizeHint</a>(). It calculates the proper size
+depending on the menu's current contents.

+<h3 class=fn>void <a name="setAccel"></a>TQMenuData::setAccel ( const&nbsp;<a href="qkeysequence.html">TQKeySequence</a>&nbsp;&amp;&nbsp;key, int&nbsp;id )
+</h3>
+Sets the accelerator key for the menu item <em>id</em> to <em>key</em>.
+<p> An accelerator key consists of a key code and a combination of the
+modifiers <a href="qt.html#Modifier-enum">SHIFT</a>, <a href="qt.html#Modifier-enum">CTRL</a>, <a href="qt.html#Modifier-enum">ALT</a> or <a href="qt.html#Modifier-enum">UNICODE_ACCEL</a> (OR'ed or
+added). The header file <a href="qnamespace-h.html">qnamespace.h</a> contains a list of key
+codes.
+<p> Defining an accelerator key produces a text that is added to the
+menu item; for instance, <a href="qt.html#Modifier-enum">CTRL</a> + <a href="qt.html#Key-enum">Key_O</a> produces "Ctrl+O". The
+text is formatted differently for different platforms.
+<p> Note that keyboard accelerators in TQt are not application-global,
+instead they are bound to a certain top-level window. For example,
+accelerators in TQPopupMenu 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 <a href="qwidget.html#parentWidget">parentWidget</a>()
+chain. The menu will then install its accelerator object on that
+top-level widget. For all other cases use an independent <a href="qaccel.html">TQAccel</a>
+object.
+<p> Example:
+<pre>
+ <a href="qmenubar.html">TQMenuBar</a> *mainMenu = new <a href="qmenubar.html">TQMenuBar</a>;
+ TQPopupMenu *fileMenu = new TQPopupMenu; // file sub menu
+ fileMenu-&gt;<a href="qmenudata.html#insertItem">insertItem</a>( "Open Document", 67 ); // add "Open" item
+ fileMenu-&gt;<a href="qmenudata.html#setAccel">setAccel</a>( CTRL + Key_O, 67 ); // Ctrl+O to open
+ fileMenu-&gt;<a href="qmenudata.html#insertItem">insertItem</a>( "Quit", 69 ); // add "Quit" item
+ fileMenu-&gt;<a href="qmenudata.html#setAccel">setAccel</a>( CTRL + ALT + Key_Delete, 69 ); // add Alt+Del to tquit
+ mainMenu-&gt;<a href="qmenudata.html#insertItem">insertItem</a>( "File", fileMenu ); // add the file menu
+ </pre>
+
+<p> If you need to translate accelerators, use <a href="qobject.html#tr">tr</a>() with a string:
+<pre>
+ fileMenu-&gt;setAccel( <a href="qobject.html#tr">tr</a>("Ctrl+O"), 67 );
+ </pre>
+
+<p> You can also specify the accelerator in the <a href="qmenudata.html#insertItem">insertItem</a>() function.
+You may prefer to use <a href="qaction.html">TQAction</a> to associate accelerators with menu
+items.
+<p> <p>See also <a href="qmenudata.html#accel">accel</a>(), <a href="qmenudata.html#insertItem">insertItem</a>(), <a href="qaccel.html">TQAccel</a>, and <a href="qaction.html">TQAction</a>.
