<p>In some situations it is useful to group actions together. For example, if you have a left justify action, a right justify action and a center action, only one of these actions should be active at any one time. One simple way of achieving this is to group the actions together in an action group.</p>
<p>An action group can also be added to a menu or a toolbar as a single unit, with all the actions within the action group appearing as separate menu options or toolbar buttons.</p>
<p>Here's a example (from the <a href="mainwindows-menus.html">Menus</a> example):</p>
<pre>
alignmentGroup = new QActionGroup(this);
alignmentGroup->addAction(leftAlignAct);
alignmentGroup->addAction(rightAlignAct);
alignmentGroup->addAction(justifyAct);
alignmentGroup->addAction(centerAct);
leftAlignAct->setChecked(true);
</pre>
<p>Here we create a new action group. Since the action group is exclusive by default, only one of the actions in the group is ever active at any one time.</p>
<p>A QActionGroup emits an <a href="qactiongroup.html#triggered">triggered</a>() signal when one of its actions is activated. Each action in an action group emits its <a href="qactiongroup.html#triggered">triggered</a>() signal as usual.</p>
<p>As stated above, an action group is <a href="qactiongroup.html#exclusive-prop">exclusive</a> by default; it ensures that only one checkable action is active at any one time. If you want to group checkable actions without making them exclusive, you can turn of exclusiveness by calling setExclusive(false).</p>
<p>Actions can be added to an action group using <a href="qactiongroup.html#addAction">addAction</a>(), but it is usually more convenient to specify a group when creating actions; this ensures that actions are automatically created with a parent. Actions can be visually separated from each other using <a href="qactiongroup-qt3.html#addSeparator">addSeparator</a>(). Action groups are added to widgets with the <a href="qwidget.html#addActions">QWidget.addActions</a>() function.</p>

<p>The action group is exclusive by default. Call setExclusive(false) to make the action group non-exclusive.</p>
<h3 class="fn"><a name="actions" />QAction-list QActionGroup.actions (<i>self</i>)</h3><p>Returns the list of this groups's actions. This may be empty.</p>
<h3 class="fn"><a name="addAction" /><a href="qaction.html">QAction</a> QActionGroup.addAction (<i>self</i>, <a href="qaction.html">QAction</a> <i>a</i>)</h3><p>Adds the <i>action</i> to this group, and returns it.</p>
<p>Normally an action is added to a group by creating it with the group as its parent, so this function is not usually used.</p>

<p>Creates and returns an action with <i>text</i>. The newly created action is a child of this action group.</p>
<p>Normally an action is added to a group by creating it with the group as parent, so this function is not usually used.</p>
