<!-- $$$QMenuBar-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>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="qmenubar.html#addMenu">addMenu</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="qmenu.html">QMenu</a>, the following statement inserts the menu into the menu bar:</p>
<pre class="cpp"> menubar<span class="operator">-</span><span class="operator">></span><a href="qmenubar.html#addMenu">addMenu</a>(fileMenu);</pre>
<p>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>
<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>
<a name="usage"></a>
<h3>Usage</h3>
<p>In most main window style applications you would use the <a href="qmainwindow.html#menuBar">menuBar()</a> function provided in <a href="qmainwindow.html">QMainWindow</a>, adding <a href="qmenu.html">QMenu</a>s to the menu bar and adding <a href="qaction.html">QAction</a>s to the pop-up menus.</p>
<p>Example (from the <a href="mainwindows-menus.html">Menus</a> example):</p>
<pre class="cpp"> fileMenu <span class="operator">=</span> menuBar()<span class="operator">-</span><span class="operator">></span>addMenu(tr(<span class="string">"&File"</span>));
fileMenu<span class="operator">-</span><span class="operator">></span>addAction(newAct);</pre>
<p>Menu items may be removed with <a href="qwidget.html#removeAction">removeAction</a>().</p>
<p>Widgets can be added to menus by using instances of the <a href="qwidgetaction.html">QWidgetAction</a> class to hold them. These actions can then be inserted into menus in the usual way; see the <a href="qmenu.html">QMenu</a> documentation for more details.</p>
<a name="platform-dependent-look-and-feel"></a>
<h3>Platform Dependent Look and Feel</h3>
<p>Different platforms have different requirements for the appearance of menu bars and their behavior when the user interacts with them. For example, Windows systems are often configured so that the underlined character mnemonics that indicate keyboard shortcuts for items in the menu bar are only shown when the <b>Alt</b> key is pressed.</p>
<table class="generic">
<tr valign="top" class="odd"><td ><img src="images/plastique-menubar.png" alt="A menu bar shown in the" /> Plastique widget style.</td><td >The <a href="qplastiquestyle.html">Plastique widget style</a>, like most other styles, handles the <b>Help</b> menu in the same way as it handles any other menu.</td></tr>
<tr valign="top" class="even"><td ><img src="images/motif-menubar.png" alt="A menu bar shown in the" /> Motif widget style.</td><td >The <a href="qmotifstyle.html">Motif widget style</a> treats <b>Help</b> menus in a special way, placing them at right-hand end of the menu bar.</td></tr>
</table>
<a name="qmenubar-on-mac-os-x"></a>
<h3>QMenuBar on Mac OS X</h3>
<p>QMenuBar on Mac OS X is a wrapper for using the system-wide menu bar. If you have multiple menu bars in one dialog the outermost menu bar (normally inside a widget with widget flag <a href="qt.html#WindowType-enum">Qt::Window</a>) will be used for the system-wide menu bar.</p>
<p>Qt for Mac OS X also provides a menu bar merging feature to make QMenuBar conform more closely to accepted Mac OS X menu bar layout. The merging functionality is based on string matching the title of a <a href="qmenu.html">QMenu</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>
<table class="generic">
<thead><tr class="qt-style"><th >String matches</th><th >Placement</th><th >Notes</th></tr></thead>
<tr valign="top" class="odd"><td >about.*</td><td >Application Menu | About <application name></td><td >The application name is fetched from the <tt>Info.plist</tt> file (see note below). If this entry is not found no About item will appear in the Application Menu.</td></tr>
<tr valign="top" class="even"><td >config, options, setup, settings or preferences</td><td >Application Menu | Preferences</td><td >If this entry is not found the Settings item will be disabled</td></tr>
<tr valign="top" class="odd"><td >quit or exit</td><td >Application Menu | Quit <application name></td><td >If this entry is not found a default Quit item will be created to call <a href="qcoreapplication.html#quit">QApplication::quit</a>()</td></tr>
</table>
<p>You can override this behavior by using the <a href="qaction.html#menuRole-prop">QAction::menuRole</a>() property.</p>
<p>If you want all windows in a Mac application to share one menu bar, you must create a menu bar that does not have a parent. Create a parent-less menu bar this way:</p>
<pre class="cpp"> <span class="type">QMenuBar</span> <span class="operator">*</span>menuBar <span class="operator">=</span> <span class="keyword">new</span> <span class="type">QMenuBar</span>(<span class="number">0</span>);</pre>
<p><b>Note:</b> Do <i>not</i> call <a href="qmainwindow.html#menuBar">QMainWindow::menuBar</a>() to create the shared menu bar, because that menu bar will have the <a href="qmainwindow.html">QMainWindow</a> as its parent. That menu bar would only be displayed for the parent <a href="qmainwindow.html">QMainWindow</a>.</p>
<p><b>Note:</b> The text used for the application name in the menu bar is obtained from the value set in the <tt>Info.plist</tt> file in the application's bundle. See <a href="deployment-mac.html">Deploying an Application on Mac OS X</a> for more information.</p>

<h3>QMenuBar on Windows CE</h3>
<p>QMenuBar on Windows CE is a wrapper for using the system-wide menu bar, similar to the Mac. This feature is activated for Windows Mobile and integrates QMenuBar with the native soft keys. The left soft key can be controlled with <a href="qmenubar.html#setDefaultAction">QMenuBar::setDefaultAction</a>() and the right soft key can be used to access the menu bar.</p>
<p>The <a href="qmenubar.html#hovered">hovered</a>() signal is not supported for the native menu integration. Also, it is not possible to display an icon in a native menu on Windows Mobile.</p>
<a name="examples"></a>
<h3>Examples</h3>
<p>The <a href="mainwindows-menus.html">Menus</a> example shows how to use QMenuBar and <a href="qmenu.html">QMenu</a>. The other <a href="examples-mainwindow.html">main window application examples</a> also provide menus using these classes.</p>

<p>This property holds the popup orientation.</p>
<p>The default popup orientation. By default, menus pop "down" the screen. By setting the property to true, the menu will pop "up". You might call this for menus that are <i>below</i> the document to which they refer.</p>

<p>This property holds whether or not a menubar will be used as a native menubar on platforms that support it.</p>
<p>This property specifies whether or not the menubar should be used as a native menubar on platforms that support it. The currently supported platforms are Mac OS X and Windows CE. On these platforms if this property is true, the menubar is used in the native menubar and is not in the window of its parent, if false the menubar remains in the window. On other platforms the value of this attribute has no effect.</p>
<p>The default is to follow whether the <a href="qt.html#ApplicationAttribute-enum">Qt::AA_DontUseNativeMenuBar</a> attribute is set for the application. Explicitly settings this property overrides the presence (or abscence) of the attribute.</p>
<p>This property was introduced in Qt 4.6.</p>

<p><b>Note:</b> <a href="qmenubar.html">QMenuBar</a> has to have ownership of the <a href="qmenu.html">QMenu</a> in order this signal to work.</p>
<p>Normally, you connect each menu action to a single slot using <a href="qaction.html#triggered">QAction::triggered</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><b>See also </b><a href="qmenubar.html#hovered">hovered</a>() and <a href="qaction.html#triggered">QAction::triggered</a>().</p>
