<hr><h2><a name="details"></a>Detailed Description</h2>
The QMenuData class is a base class for <a href="qmenubar.html">QMenuBar</a> and <a href="qpopupmenu.html">QPopupMenu</a>.
<p>
QMenuData has an internal list of menu items. A menu item is a text,
pixmap or a separator, and may also have a popup menu (separators
have no popup menus).
<p>The menu item sends out an activated() signal when it is selected, and
a highlighted() signal when it receives the user input focus.
<p>Menu items can be accessed through identifiers.
<p>See also <a href="qaccel.html">QAccel</a>.

<p>The family of insertItem() functions inserts menu items into a
popup menu or a menu bar.
<p>A menu item is usually either a text string or a a pixmap, both with
an optional icon or keyboard accelerator. As 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 additional
argument. Use these to insert submenus to existing menus or pulldown
menus to a menu bar.
<p>The amount of insert functions may look confusing, but is actually
quite handy to use.
<p>This default version inserts a menu item with a text, an accelerator
key, an id and an optional index and connects it to an object/slot.
<p>Example:
<pre> <a href="qmenubar.html">QMenuBar</a> *mainMenu = new <a href="qmenubar.html">QMenuBar</a>;
<a href="qpopupmenu.html">QPopupMenu</a> *fileMenu = new <a href="qpopupmenu.html">QPopupMenu</a>;
fileMenu-><a href="#0076cb">insertItem</a>( "New", myView, SLOT(newFile()), CTRL+Key_N );
fileMenu-><a href="#0076cb">insertItem</a>( "Open", myView, SLOT(open()), CTRL+Key_O );
mainMenu-><a href="#0076cb">insertItem</a>( "File", fileMenu );
</pre>
<p>Not all insert functions take an object/slot parameter or an
accelerator key. Use <a href="#d7f757">connectItem</a>() and <a href="#58b23b">setAccel</a>() on these items.
<p>If you will need to translate accelerators, use <a href="qaccel.html#3ff091">QAccel::stringToKey</a>()
to calculate the accelerator key:
<pre> fileMenu->insertItem( tr("Open"), myView, SLOT(open()),
<a href="qaccel.html#3ff091">QAccel::stringToKey</a>( tr("Ctrl+O") ) );
</pre>
<p>In the example above, pressing CTRL+N 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 menu 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 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, but
bound to a certain toplevel window. Accelerators in <a href="qpopupmenu.html">QPopupMenu</a> items
therefore only work for menus that are associated with a certain
window. This is true for popup menus that live in a menu bar, for
instance. In that case, the accelerator will be installed on the
menu bar itself. It also works for stand-alone popup menus that have
a toplevel widget in their parentWidget()- chain. The menu will then
install its accelerator object on that toplevel 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 insertItem(), as
some C++ compilers choose the wrong overloaded function.
Cast the 0 to what you mean, eg. <tt>(<a href="qobject.html">QObject</a>*)0</tt>.

<h3 class="fn">int<a name="230967"></a>QMenuData::insertItem(<a href="qcustommenuitem.html">QCustomMenuItem</a>*custom, intid=-1, intindex=-1)</h3>
<p>This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
<p>Inserts a custom menu item <em>custom.</em>
<p>This only works with popup menus. It is not supported for menu bars.
Ownership of <em>custom</em> is transferred to the popup menu.
<p>If you want to connect a custom item to a certain slot, use <a href="#d7f757">connectItem</a>().

<h3 class="fn">int<a name="e53049"></a>QMenuData::insertItem(<a href="qwidget.html">QWidget</a>*widget, intid=-1, intindex=-1)</h3>
<p>This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
<p>Inserts a menu item that consists of the widget <em>widget.</em>
<p>Ownership of <em>widget</em> is transferred to the popup menu or the
menubar.
<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#2f25f0">QWidget::isFocusEnabled</a>() ),
the menu treats it as a separator. This means, the item is not
selectable and will never get focus. 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 ArrowUp and ArrowDown in its key event handler, the focus
will move back to the menu when the the respective arrow key is hit
one more time. This works for example with a <a href="qlineedit.html">QLineEdit</a>. If the
widget accepts the arrow keys itself, it must also provide the
possibility to put the focus back on the menu again by calling
<a href="qwidget.html#8d74a1">QWidget::focusNextPrevChild</a>() respectively. Futhermore should the
embedded widget close the menu when the user made a selection. This
can be done safely by calling <pre> if ( isVisible() &&
parentWidget() &&
parentWidget()->inherits("QPopupMenu") )
parentWidget()->close();

<h3 class="fn">void<a name="58b23b"></a>QMenuData::setAccel(intkey, intid)</h3>
<p>Defines an accelerator key for the menu item <em>id.</em>
<p>An accelerator key consists of a key code and a combination of the modifiers
<code>SHIFT, CTRL, ALT,</code> or <code>UNICODE_ACCEL</code> (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 generates a text which is added to the
menu item, for instance, <code>CTRL</code> + <code>Key_O</code> generates "Ctrl+O". The
text is formatted differently for different platforms.
<p>Note that keyboard accelerators in Qt are not application global, but
bound to a certain toplevel window. Accelerators in <a href="qpopupmenu.html">QPopupMenu</a> items
therefore only work for menus that are associated with a certain
window. This is true for popup menus that live in a menu bar, for
instance. In that case, the accelerator will be installed on the
menu bar itself. It also works for stand-alone popup menus that have
a toplevel widget in their parentWidget()- chain. The menu will then
install its accelerator object on that toplevel 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>;
<a href="qpopupmenu.html">QPopupMenu</a> *fileMenu = new <a href="qpopupmenu.html">QPopupMenu</a>; // file sub menu

fileMenu-><a href="#58b23b">setAccel</a>( CTRL + Key_O, 67 ); // Control and O to open
fileMenu-><a href="#0076cb">insertItem</a>( "Quit", 69 ); // add "Quit" item
fileMenu-><a href="#58b23b">setAccel</a>( CTRL + ALT + Key_Delete, 69 );
mainMenu-><a href="#0076cb">insertItem</a>( "File", fileMenu ); // add the file menu
</pre>
<p>If you will need to translate accelerators, use <a href="qaccel.html#3ff091">QAccel::stringToKey</a>():
<p><pre> fileMenu->setAccel( <a href="qaccel.html#3ff091">QAccel::stringToKey</a>(tr("Ctrl+O")), 67 );
