<hr><a name="details"></a><h2>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>
<p> QMenuData has an internal list of menu items. A menu item is a text,
pixmap or separator, and may also have a popup menu (separators
have no popup menus).
<p> The menu item sends out an <a href="qmenubar.html#activated">activated()</a> signal when it is selected and a <a href="qmenubar.html#highlighted">highlighted()</a> signal when it
receives the user input focus.
<p> <!-- index menu identifier --><a name="menu-identifier"></a>
<p> Menu items are assigned the menu identifier <em>id</em> that is passed in
<a href="#insertItem">insertItem</a>() or an automatically generated identifier if <em>id</em> 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.
<p> Menu items can be removed with <a href="#removeItem">removeItem</a>() or changed with
<a href="#changeItem">changeItem</a>(). Accelerators can be changed or set with <a href="#setAccel">setAccel</a>().
Checkable items can be checked or unchecked with <a href="#setItemChecked">setItemChecked</a>().
Items can be enabled or disabled using <a href="#setItemEnabled">setItemEnabled</a>() and
connected and disconnected with <a href="#connectItem">connectItem</a>() and <a href="#disconnectItem">disconnectItem</a>()
respectively.
<p> Menu items are stored in a list. Use <a href="#findItem">findItem</a>() to find an item by
its list position or by its menu identifier.

</h3>
The family of <a href="#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 to existing menus or pulldown
menus to 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>;
<a href="qpopupmenu.html">QPopupMenu</a> *fileMenu = new <a href="qpopupmenu.html">QPopupMenu</a>;
fileMenu-><a href="#insertItem">insertItem</a>( "New", myView, SLOT(newFile()), CTRL+Key_N );
fileMenu-><a href="#insertItem">insertItem</a>( "Open", myView, SLOT(open()), CTRL+Key_O );
mainMenu-><a href="#insertItem">insertItem</a>( "File", fileMenu );
</pre>
<p> Not all insert functions take an object/slot parameter or an
accelerator key. Use <a href="#connectItem">connectItem</a>() and <a href="#setAccel">setAccel</a>() on these items.
<p> If you need to translate accelerators, use tr() with a string
description that use pass to the <a href="qkeysequence.html">QKeySequence</a> constructor:
<pre>
fileMenu->insertItem( tr("Open"), myView, SLOT(open()),
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 <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 <a href="qpopupmenu.html">QPopupMenu</a> 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 <a href="qaccel.html">QAccel</a> object.
<p> <b>Warning:</b> Be careful when passing a literal 0 to <a href="#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> 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>.
<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 ArrowUp and ArrowDown 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 ( isVisible() &&
parentWidget() &&
parentWidget()->inherits("QPopupMenu") )
parentWidget()->close();
</pre>
<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 custom menu item <em>custom</em> with an <em>icon</em> and with
optional id <em>id</em>, and optional <em>index</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="#connectItem">connectItem</a>().
<p> Returns the allocated <a href="qmenudata.html#menu-identifier">menu identifier</a> number (<em>id</em> if <em>id</em> >= 0).

<p> Inserts a custom menu item <em>custom</em> with
optional id <em>id</em>, and optional <em>index</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="#connectItem">connectItem</a>().

<p> <p>See also <a href="#connectItem">connectItem</a>(), <a href="#removeItem">removeItem</a>() and <a href="qcustommenuitem.html">QCustomMenuItem</a>.
<h3 class=fn>int <a name="insertSeparator"></a>QMenuData::insertSeparator ( int index = -1 )
</h3>
Inserts a separator at position <em>index</em>.
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
Motif 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>

<p>See also <a href="#removeItem">removeItem</a>() and <a href="#clear">clear</a>().
<h3 class=fn>void <a name="setAccel"></a>QMenuData::setAccel ( const <a href="qkeysequence.html">QKeySequence</a> & key, int 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
<tt>SHIFT</tt>, <tt>CTRL</tt>, <tt>ALT</tt> or <tt>UNICODE_ACCEL</tt> (OR'ed or added).
The header file qnamespace.h contains a list of key codes.
<p> Defining an accelerator key produces a text that is added to the
menu item; for instance, <tt>CTRL</tt> + <tt>Key_O</tt> 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 <a href="qpopupmenu.html">QPopupMenu</a> 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 <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="#insertItem">insertItem</a>( "Open Document", 67 ); // add "Open" item
fileMenu-><a href="#setAccel">setAccel</a>( CTRL + Key_O, 67 ); // Control and O to open
fileMenu-><a href="#insertItem">insertItem</a>( "Quit", 69 ); // add "Quit" item
fileMenu-><a href="#setAccel">setAccel</a>( CTRL + ALT + Key_Delete, 69 );
mainMenu-><a href="#insertItem">insertItem</a>( "File", fileMenu ); // add the file menu
</pre>
<p> If you need to translate accelerators, use tr() with a string:
<pre>
fileMenu->setAccel( tr("Ctrl+O"), 67 );
</pre>
<p> You can also specify the accelerator in the <a href="#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="#accel">accel</a>(), <a href="#insertItem">insertItem</a>(), <a href="qaccel.html">QAccel</a> and <a href="qaction.html">QAction</a>.
<p>Example: <a href="menu-example.html#x1125">menu/menu.cpp</a>.
<h3 class=fn>void <a name="setId"></a>QMenuData::setId ( int index, int id )<tt> [virtual]</tt>
</h3>

<p> <p>See also <a href="#idAt">idAt</a>().
<h3 class=fn>void <a name="setItemChecked"></a>QMenuData::setItemChecked ( int id, bool check )
</h3>
If <em>check</em> is TRUE, checks the menu item with id <em>id</em>; otherwise
