<hr><a name="details"></a><h2>Detailed Description</h2>
The QMenuBar class provides a horizontal menu bar.
<p>
<p> A menu bar consists of a list of pull-down menu items. You add
menu items with <a href="qmenudata.html#insertItem">insertItem()</a>. For example, asuming that <tt>menubar</tt> is a
pointer to a QMenuBar and <tt>filemenu</tt> is a pointer to a
<a href="qpopupmenu.html">QPopupMenu</a>, the following statement inserts the menu into the menu
bar:
<pre>
menubar->insertItem( "&File", filemenu );
</pre>
The ampersand in the menu item's text sets Alt+F as a shortcut for
this menu. (You can use "&&" to get a real ampersand in the menu
bar.)
<p> Items are either enabled or disabled. You toggle their state with
<a href="qmenudata.html#setItemEnabled">setItemEnabled</a>().
<p> There is no need to lay out a menu bar. It automatically sets its
own geometry to the top of the parent widget and changes it
appropriately whenever the parent is resized.
<p>
<p> Example of creating a menu bar with menu items (from <a href="menu-example.html">menu/menu.cpp</a>):
<pre> <a href="qpopupmenu.html">QPopupMenu</a> *file = new <a href="qpopupmenu.html">QPopupMenu</a>( this );
</pre><pre> file-><a href="qmenudata.html#insertItem">insertItem</a>( p1, "&Open", this, SLOT(open()), CTRL+Key_O );
file-><a href="qmenudata.html#insertItem">insertItem</a>( p2, "&New", this, SLOT(news()), CTRL+Key_N );
</pre><pre> menu = new QMenuBar( this );
</pre><pre> menu-><a href="qmenudata.html#insertItem">insertItem</a>( "&File", file );
</pre>
<p> In most main window style applications you would use the menuBar()
provided in <a href="qmainwindow.html">QMainWindow</a>, adding <a href="qpopupmenu.html">QPopupMenu</a>s to the menu bar
and adding <a href="qaction.html">QAction</a>s to the popup menus.
<p> Example (from <a href="qaction-application-example.html">action/application.cpp</a>):
<pre> <a href="qpopupmenu.html">QPopupMenu</a> * file = new <a href="qpopupmenu.html">QPopupMenu</a>( this );
<a href="qmainwindow.html#menuBar">menuBar</a>()->insertItem( "&File", file );
fileNewAction-><a href="qaction.html#addTo">addTo</a>( file );
</pre>
<p> Menu items can have text and pixmaps (or iconsets), see the
various <a href="qmenudata.html#insertItem">insertItem()</a>
overloads, as well as separators, see <a href="qmenudata.html#insertSeparator">insertSeparator()</a>. You can
also add custom menu items that are derived from
<a href="qcustommenuitem.html">QCustomMenuItem</a>.
<p> Menu items may be removed with <a href="qmenudata.html#removeItem">removeItem</a>() and enabled or
disabled with <a href="qmenudata.html#setItemEnabled">setItemEnabled()</a>.

<p> <h3> QMenuBar on Qt/Mac
</h3>
<a name="1"></a><p> QMenuBar on Qt/Mac is a wrapper for using the system-wide menubar.
If you have multiple menubars in one dialog the outermost menubar
(normally inside a widget with <a href="qt.html#WidgetFlags">widget flag</a> <a href="qt.html#WidgetFlags-enum">WType_TopLevel</a>) will
be used for the system-wide menubar.
<p> Note that arbitrary Qt widgets <em>cannot</em> be inserted into a
QMenuBar on the Mac because Qt uses Mac's native menus which don't
support this functionality. This limitation does not apply to
stand-alone QPopupMenus.
<p> Qt/Mac also provides a menubar merging feature to make QMenuBar
conform more closely to accepted Mac OS X menubar layout. The
merging functionality is based on string matching the title of a
<a href="qpopupmenu.html">QPopupMenu</a> entry. These strings are translated (using
<a href="qobject.html#tr">QObject::tr</a>()) in the "QMenuBar" context. If an entry is moved its
slots will still fire as if it was in the original place. The
table below outlines the strings looked for and where the entry is
placed if matched:
<p> <center><table cellpadding="4" cellspacing="2" border="0">
<tr bgcolor="#a2c511"> <th valign="top">String matches <th valign="top">Placement <th valign="top">Notes
<tr bgcolor="#f0f0f0"> <td valign="top">about.*
<td valign="top">Application Menu | About <application name>
<td valign="top">If this entry is not found no About item will appear in
the Application Menu
<tr bgcolor="#d0d0d0"> <td valign="top">config, options, setup, settings or preferences
<td valign="top">Application Menu | Preferences
<td valign="top">If this entry is not found the Settings item will be disabled
<tr bgcolor="#f0f0f0"> <td valign="top">quit or exit
<td valign="top">Application Menu | Quit <application name>
<td valign="top">If this entry is not found a default Quit item will be
created to call <a href="qapplication.html#quit">QApplication::quit</a>()
</table></center>
<p> <a href="menu-example.html">menu/menu.cpp</a> is an example of
QMenuBar and <a href="qpopupmenu.html">QPopupMenu</a> use.

<hr><h2>Member Type Documentation</h2>
<h3 class=fn><a name="Separator-enum"></a>QMenuBar::Separator</h3>
<p> This enum type is used to decide whether QMenuBar should draw a
separator line at its bottom.
<ul>
<li><tt>QMenuBar::Never</tt> - In many applications there is already a separator,
and having two looks wrong.
<li><tt>QMenuBar::InWindowsStyle</tt> - In some other applications a separator looks
good in Windows style, but nowhere else.
</ul>
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QMenuBar"></a>QMenuBar::QMenuBar ( <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0 )
</h3>
Constructs a menu bar called <em>name</em> with parent <em>parent</em>.
<h3 class=fn><a name="~QMenuBar"></a>QMenuBar::~QMenuBar ()
</h3>
Destroys the menu bar.
<h3 class=fn>void <a name="activated"></a>QMenuBar::activated ( int 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 will 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>().
<p>Example: <a href="progress-example.html#x67">progress/progress.cpp</a>.
<h3 class=fn>void <a name="clear"></a>QMenuData::clear ()
</h3>
Removes all menu items.
<p> <p>See also <a href="qmenudata.html#removeItem">removeItem</a>() and <a href="qmenudata.html#removeItemAt">removeItemAt</a>().
<p>Examples: <a href="mdi-example.html#x2029">mdi/application.cpp</a> and <a href="qwerty-example.html#x370">qwerty/qwerty.cpp</a>.
<h3 class=fn>void <a name="drawContents"></a>QMenuBar::drawContents ( <a href="qpainter.html">QPainter</a> * p )<tt> [virtual protected]</tt>
</h3>
Called from <a href="qframe.html#paintEvent">QFrame::paintEvent</a>(). Draws the menu bar contents
using painter <em>p</em>.
<p>Reimplemented from <a href="qframe.html#drawContents">QFrame</a>.
<h3 class=fn>int <a name="heightForWidth"></a>QMenuBar::heightForWidth ( int max_width ) const<tt> [virtual]</tt>

Returns the height that the menu would resize itself to if its
parent (and hence itself) resized to the given <em>max_width</em>. This
can be useful for simple layout tasks in which the height of the
menu bar is needed after items have been inserted. See <a href="showimg-example.html">showimg/showimg.cpp</a> for an example of the usage.

<h3 class=fn>void <a name="highlighted"></a>QMenuBar::highlighted ( int 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> Normally, you will 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="#activated">activated</a>() and <a href="qmenudata.html#insertItem">QMenuData::insertItem</a>().
<h3 class=fn>int <a name="insertItem"></a>QMenuData::insertItem ( const <a href="qstring.html">QString</a> & text, const <a href="qobject.html">QObject</a> * receiver, const char * member, const <a href="qkeysequence.html">QKeySequence</a> & accel = 0, int id = -1, int 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>
QMenuBar *mainMenu = new QMenuBar;
<a href="qpopupmenu.html">QPopupMenu</a> *fileMenu = new <a href="qpopupmenu.html">QPopupMenu</a>;
fileMenu-><a href="qmenudata.html#insertItem">insertItem</a>( "New", myView, SLOT(newFile()), CTRL+Key_N );
fileMenu-><a href="qmenudata.html#insertItem">insertItem</a>( "Open", myView, SLOT(open()), CTRL+Key_O );
mainMenu-><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->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 <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 <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.

</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>() &&
<a href="qwidget.html#parentWidget">parentWidget</a>() &&
<a href="qwidget.html#parentWidget">parentWidget</a>()->inherits("QPopupMenu") )

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).
