The QPopupMenu 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">QMenuBar::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">QCustomMenuItem</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 QPopupMenu 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, QPopupMenu 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">QWhatsThis</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 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 <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">QToolBar</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">QMenuBar</a> and QPopupMenu use.

<h3 class=fn><a name="QPopupMenu"></a>QPopupMenu::QPopupMenu ( <a href="qwidget.html">QWidget</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">QObject</a>).

<h3 class=fn><a name="~QPopupMenu"></a>QPopupMenu::~QPopupMenu ()
</h3>
Destroys the popup menu.

<h3 class=fn>void <a name="aboutToHide"></a>QPopupMenu::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>QPopupMenu::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">QKeySequence</a> <a name="accel"></a>QMenuData::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">QAccel</a>, and <a href="qnamespace-h.html">qnamespace.h</a>.

<h3 class=fn>void <a name="activated"></a>QPopupMenu::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">QMenuData::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">QMenuData::insertItem</a>().

for accelerator text.
<p> <p>See also <a href="qstyle.html#drawControl">QStyle::drawControl</a>().

<h3 class=fn>int <a name="exec"></a>QPopupMenu::exec ()
</h3>
Executes this popup synchronously.
<p> This is equivalent to <tt>exec(mapToGlobal(QPoint(0,0)))</tt>. In most
situations you'll want to specify the position yourself, for
example at the current mouse position:
<pre>
        <a href="#exec">exec</a>(QCursor::<a href="qcursor.html#pos">pos</a>());
    </pre>
 
or aligned to a widget:
<pre>
        <a href="#exec">exec</a>(somewidget.mapToGlobal(QPoint(0,0)));
    </pre>
 

<p>Examples: <a href="fileiconview-example.html#x866">fileiconview/qfileiconview.cpp</a>, <a href="menu-example.html#x1878">menu/menu.cpp</a>, and <a href="scribble-example.html#x923">scribble/scribble.cpp</a>.
<h3 class=fn>int <a name="exec-2"></a>QPopupMenu::exec ( const&nbsp;<a href="qpoint.html">QPoint</a>&nbsp;&amp;&nbsp;pos, int&nbsp;indexAtPoint = 0 )
</h3>
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">QWidget::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>( QCursor::<a href="qcursor.html#pos">pos</a>() );
    </pre>
 
or aligned to a widget:
<pre>
        <a href="#exec">exec</a>( somewidget.mapToGlobal(QPoint(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
depending on the menu's current contents.
<p> <p>See also <a href="#popup">popup</a>() and <a href="qwidget.html#sizeHint-prop">sizeHint</a>.

<h3 class=fn>void <a name="highlighted"></a>QPopupMenu::highlighted ( int&nbsp;id )<tt> [signal]</tt>
</h3>

<p> This signal is emitted when a menu item is highlighted; <em>id</em> is
the id of the highlighted item.
<p> <p>See also <a href="#activated">activated</a>() and <a href="qmenudata.html#insertItem">QMenuData::insertItem</a>().

<h3 class=fn><a href="qiconset.html">QIconSet</a>&nbsp;* <a name="iconSet"></a>QMenuData::iconSet ( int&nbsp;id ) const
</h3>
Returns the icon set that has been set for menu item <em>id</em>, or 0
if no icon set has been set.
<p> <p>See also <a href="qmenudata.html#changeItem">changeItem</a>(), <a href="qmenudata.html#text">text</a>(), and <a href="qmenudata.html#pixmap">pixmap</a>().

<h3 class=fn>int <a name="idAt"></a>QPopupMenu::idAt ( int&nbsp;index ) const
</h3>

<p> Returns the identifier of the menu item at position <em>index</em> in
the internal list, or -1 if <em>index</em> is out of range.
<p> <p>See also <a href="qmenudata.html#setId">QMenuData::setId</a>() and <a href="qmenudata.html#indexOf">QMenuData::indexOf</a>().

<p>Example: <a href="scrollview-example.html#x643">scrollview/scrollview.cpp</a>.
<h3 class=fn>int <a name="idAt-2"></a>QPopupMenu::idAt ( const&nbsp;<a href="qpoint.html">QPoint</a>&nbsp;&amp;&nbsp;pos ) const
</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Returns the id of the item at <em>pos</em>, or -1 if there is no item
there or if it is a separator.

<h3 class=fn>int <a name="insertItem"></a>QMenuData::insertItem ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;text, const&nbsp;<a href="qobject.html">QObject</a>&nbsp;*&nbsp;receiver, const&nbsp;char&nbsp;*&nbsp;member, const&nbsp;<a href="qkeysequence.html">QKeySequence</a>&nbsp;&amp;&nbsp;accel = 0, int&nbsp;id = -1, int&nbsp;index = -1 )
</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">QCustomMenuItem</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 quite 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">QMenuBar</a>   *mainMenu = new <a href="qmenubar.html">QMenuBar</a>;
        QPopupMenu *fileMenu = new QPopupMenu;
        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">QIconSet</a> parameter to specify the
little menu item icon. Note that you can always pass a <a href="qpixmap.html">QPixmap</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 Qt 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 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 <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">QAccel</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>(QObject*)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 Qt
version.
<p> Returns the allocated <a href="qmenudata.html#menu-identifier">menu identifier</a> number (<em>id</em> if <em>id</em> >= 0).

</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Inserts a menu item that consists of the widget <em>widget</em> with
optional id <em>id</em>, and optional <em>index</em> position.
<p> Ownership of <em>widget</em> is transferred to the popup menu or to the
menu bar.
<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">QWidget::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">QLabel</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">QLineEdit</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">QWidget::focusNextPrevChild</a>(). Futhermore, if the embedded widget
closes the menu when the user made a selection, this can be done
safely by calling:
<pre>
        if ( <a href="qwidget.html#isVisible">isVisible</a>() &amp;&amp;
             <a href="qwidget.html#parentWidget">parentWidget</a>() &amp;&amp;

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>QPopupMenu::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>QPopupMenu::popup ( const&nbsp;<a href="qpoint.html">QPoint</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">QWidget::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>QMenuData::setAccel ( const&nbsp;<a href="qkeysequence.html">QKeySequence</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 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 <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">QAccel</a>
object.
<p> Example:
<pre>
        <a href="qmenubar.html">QMenuBar</a> *mainMenu = new <a href="qmenubar.html">QMenuBar</a>;
        QPopupMenu *fileMenu = new QPopupMenu;       // 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 quit
        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">QAction</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">QAccel</a>, and <a href="qaction.html">QAction</a>.
