The TQMenuData class is a base class for <a href="tqmenubar.html">TQMenuBar</a> and <a href="tqpopupmenu.html">TQPopupMenu</a>.
<p> 
<p> TQMenuData has an internal list of menu items. A menu item can have
a <a href="#text">text</a>(), an <a href="#accel">accelerator</a>, a <a href="#pixmap">pixmap</a>(), an
<a href="#iconSet">iconSet</a>(), a <a href="#whatsThis">whatsThis</a>() text and a popup menu (unless it is a
separator). Menu items may optionally be <a href="#setItemChecked">checked</a> (except for separators).
<p> The menu item sends out an <a href="tqmenubar.html#activated">activated()</a> signal when it is chosen and a <a href="tqmenubar.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

</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="tqcustommenuitem.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 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="tqmenubar.html">TQMenuBar</a>   *mainMenu = new <a href="tqmenubar.html">TQMenuBar</a>;
        <a href="tqpopupmenu.html">TQPopupMenu</a> *fileMenu = new <a href="tqpopupmenu.html">TQPopupMenu</a>;
        fileMenu-&gt;<a href="#insertItem">insertItem</a>( "New",  myView, TQ_SLOT(newFile()), CTRL+Key_N );
        fileMenu-&gt;<a href="#insertItem">insertItem</a>( "Open", myView, TQ_SLOT(open()),    CTRL+Key_O );
        mainMenu-&gt;<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 those items.
<p> If you need to translate accelerators, use tr() with the text and
accelerator. (For translations use a string <a href="tqkeysequence.html">key
    sequence</a>.):
<pre>
        fileMenu-&gt;insertItem( tr("Open"), myView, TQ_SLOT(open()),
                              tr("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="tqiconset.html">TQIconSet</a> parameter to specify the
little menu item icon. Note that you can always pass a <a href="tqpixmap.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 <a href="tqpopupmenu.html">TQPopupMenu</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="tqaccel.html">TQAccel</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>(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.

<h3 class=fn>int <a name="insertItem-d"></a>TQMenuData::insertItem ( <a href="tqwidget.html">TQWidget</a>&nbsp;*&nbsp;widget, int&nbsp;id = -1, int&nbsp;index = -1 )
</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="tqwidget.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="tqlabel.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="tqlineedit.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="tqwidget.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>
        if ( isVisible() &amp;&amp;
             parentWidget() &amp;&amp;
             parentWidget()-&gt;inherits("TQPopupMenu") )
            parentWidget()-&gt;close();
    </pre>

</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> position.
<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 slot, use <a href="#connectItem">connectItem</a>().
<p> Returns the allocated <a href="tqmenudata.html#menu-identifier">menu identifier</a> number (<em>id</em> if <em>id</em> >= 0).

<h3 class=fn>int <a name="insertSeparator"></a>TQMenuData::insertSeparator ( int&nbsp;index = -1 )
</h3>
Inserts a separator at position <em>index</em>, and returns the <a href="tqmenudata.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
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).

<p>Example: <a href="canvas-chart-example.html#x2885">chart/chartform.cpp</a>.
<h3 class=fn>void <a name="removeItemAt"></a>TQMenuData::removeItemAt ( int&nbsp;index )

<h3 class=fn>void <a name="setAccel"></a>TQMenuData::setAccel ( const&nbsp;<a href="tqkeysequence.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 <tt>SHIFT</tt>, <tt>CTRL</tt>, <tt>ALT</tt> or <tt>UNICODE_ACCEL</tt> (OR'ed or
added). The header file <a href="tqnamespace-h.html">tqnamespace.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, <tt>CTRL</tt> + <tt>Key_O</tt> 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 <a href="tqpopupmenu.html">TQPopupMenu</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="tqaccel.html">TQAccel</a>
object.
<p> Example:
<pre>
        <a href="tqmenubar.html">TQMenuBar</a> *mainMenu = new <a href="tqmenubar.html">TQMenuBar</a>;
        <a href="tqpopupmenu.html">TQPopupMenu</a> *fileMenu = new <a href="tqpopupmenu.html">TQPopupMenu</a>;       // file sub menu
        fileMenu-&gt;<a href="#insertItem">insertItem</a>( "Open Document", 67 ); // add "Open" item
        fileMenu-&gt;<a href="#setAccel">setAccel</a>( CTRL + Key_O, 67 );      // Ctrl+O to open
        fileMenu-&gt;<a href="#insertItem">insertItem</a>( "Quit", 69 );          // add "Quit" item
        fileMenu-&gt;<a href="#setAccel">setAccel</a>( CTRL + ALT + Key_Delete, 69 ); // add Alt+Del to quit
        mainMenu-&gt;<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-&gt;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="tqaction.html">TQAction</a> to associate accelerators with menu
items.
<p> <p>See also <a href="#accel">accel</a>(), <a href="#insertItem">insertItem</a>(), <a href="tqaccel.html">TQAccel</a>, and <a href="tqaction.html">TQAction</a>.

<p> If <em>index</em> is out of range, the operation is ignored.
<p> <p>See also <a href="#idAt">idAt</a>().

<h3 class=fn>void <a name="setItemChecked"></a>TQMenuData::setItemChecked ( int&nbsp;id, bool&nbsp;check )
