and other popup menus.</p>
<p>A menu widget is a selection menu. It can be either a pull-down menu in a menu bar or a standalone context menu. Pull-down menus are shown by the menu bar when the user clicks on the respective item or presses the specified shortcut key. Use <a href="qmenubar.html#addMenu">QMenuBar.addMenu</a>() to insert a menu into a menu bar. Context menus are usually invoked by some special keyboard key or by right-clicking. They can be executed either asynchronously with <a href="qmenu.html#popup">popup</a>() or synchronously with <a href="qmenu.html#exec">exec_</a>(). Menus can also be invoked in response to button presses; these are just like context menus except for how they are invoked.</p>
<p>A menu consists of a list of action items. Actions are added with <a href="qmenu.html#addAction">addAction</a>(). An action is represented vertically and rendered by <a href="qstyle.html">QStyle</a>. In addition, actions can have a text label, an optional icon drawn on the very left side, and shortcut key sequence such as "Ctrl+X".</p>
<p>There are three kinds of action items: separators, actions that show a submenu, and actions that perform an action. Separators are inserted with <a href="qmenu.html#addSeparator">addSeparator</a>(). For submenus use <a href="qmenu.html#addMenu">addMenu</a>(). All other items are considered action items.</p>
<p>When inserting action items you usually specify a receiver and a slot. The receiver will be notifed whenever the item is <a href="qaction.html#triggered">triggered()</a>. In addition, QMenu provides two signals, <a href="qmenu-qt3.html#activated">activated</a>() and <a href="qmenu-qt3.html#highlighted">highlighted</a>(), which signal the <a href="qaction.html">QAction</a> that was triggered from the menu.</p>
<p>You clear a menu with <a href="qmenu.html#clear">clear</a>() and remove individual action items with <a href="qwidget.html#removeAction">removeAction</a>().</p>
<p>A QMenu can also provide a tear-off menu. A tear-off menu is a top-level window that contains a copy of the menu. This makes it possible for the user to "tear off" frequently used menus and position them in a convenient place on the screen. If you want this functionality for a particular menu, insert a tear-off handle with <a href="qmenu.html#tearOffEnabled-prop">setTearOffEnabled</a>(). When using tear-off menus, bear in mind that the concept isn't typically used on Microsoft Windows so some users may not be familiar with it. Consider using a <a href="qtoolbar.html">QToolBar</a> instead.</p>
<p>See the <a href="mainwindows-menus.html">Menus Example</a> for an example of how to use <a href="qmenubar.html">QMenuBar</a> and QMenu in your application.</p>

<p>This functions returns the number of columns necessary.</p>
<h3 class="fn"><a name="defaultAction" /><a href="qaction.html">QAction</a> QMenu.defaultAction (<i>self</i>)</h3><p>Returns the current default action.</p>

<p>This is equivalent to <tt>exec(pos())</tt>.</p>
<p>This returns the triggered <a href="qaction.html">QAction</a> in either the popup menu or one of its submenus, or 0 if no item was triggered (normally because the user pressed Esc).</p>
<p>In most situations you'll want to specify the position yourself, for example, the current mouse position:</p>
<pre>
exec(QCursor.pos());
</pre>
<p>or aligned to a widget:</p>
<pre>
exec(somewidget.mapToGlobal(QPoint(0,0)));
</pre>
<p>or in reaction to a <a href="qmouseevent.html">QMouseEvent</a> *e:</p>
<pre>
exec(e->globalPos());
</pre>
<h3 class="fn"><a name="exec-2" /><a href="qaction.html">QAction</a> QMenu.exec_ (<i>self</i>, <a href="qpoint.html">QPoint</a> <i>pos</i>, <a href="qaction.html">QAction</a> <i>at</i> = None)</h3><p>This is an overloaded member function, provided for convenience.</p>
<p>Executes this menu synchronously.</p>
<p>Pops up the menu so that the action <i>action</i> will be at the specified <i>global</i> position <i>p</i>. To translate a widget's local coordinates into global coordinates, use <a href="qwidget.html#mapToGlobal">QWidget.mapToGlobal</a>().</p>
<p>This returns the triggered <a href="qaction.html">QAction</a> in either the popup menu or one of its submenus, or 0 if no item was triggered (normally because the user pressed Esc).</p>
<p>Note that all signals are emitted as usual. If you connect a <a href="qaction.html">QAction</a> to a slot and call the menu's <a href="qmenu.html#exec">exec_</a>(), you get the result both via the signal-slot connection and in the return value of <a href="qmenu.html#exec">exec_</a>().</p>
<p>Common usage is to position the menu at the current mouse position:</p>
<pre>
exec(QCursor.pos());
</pre>
<p>or aligned to a widget:</p>
<pre>
exec(somewidget.mapToGlobal(QPoint(0, 0)));
</pre>
<p>or in reaction to a <a href="qmouseevent.html">QMouseEvent</a> *e:</p>
<pre>
exec(e->globalPos());
</pre>
<p>When positioning a menu with <a href="qmenu.html#exec">exec_</a>() or <a href="qmenu.html#popup">popup</a>(), bear in mind that you cannot rely on the menu's current <a href="qwidget.html#size-prop">size</a>(). For performance reasons, the menu adapts its size only when necessary. So in many cases, the size before and after the show is different. Instead, use <a href="qwidget.html#sizeHint-prop">sizeHint</a>() which calculates the proper size depending on the menu's current contents.</p>

<p>Executes this menu synchronously.</p>
<p>The menu's actions are specified by the list of <i>actions</i>. The menu will pop up so that the specified action, <i>at</i>, appears at global position <i>pos</i>. If <i>at</i> is not specified then the menu appears at position <i>pos</i>.</p>
<p>The function returns the triggered <a href="qaction.html">QAction</a> in either the popup menu or one of its submenus, or 0 if no item was triggered (normally because the user pressed Esc).</p>
<p>This is equivalent to:</p>
<pre>
QMenu menu;
QAction *at = actions[0]; // Assumes actions is not empty
foreach (QAction *a, actions)
menu.addAction(a);
menu.exec(pos, at);

<p>When positioning a menu with <a href="qmenu.html#exec">exec_</a>() or popup(), bear in mind that you cannot rely on the menu's current <a href="qwidget.html#size-prop">size</a>(). For performance reasons, the menu adapts its size only when necessary, so in many cases, the size before and after the show is different. Instead, use <a href="qwidget.html#sizeHint-prop">sizeHint</a>() which calculates the proper size depending on the menu's current contents.</p>

<p>Normally, you connect each menu action's <a href="qaction.html#triggered">triggered()</a> signal to its own custom slot, but sometimes you will want to connect several actions to a single slot, for example, when you have a group of closely related actions, such as "left justify", "center", "right justify".</p>
