class="link" href="GtkLabel.html" title="GtkLabel"><span class="type">GtkLabel</span></a> that also displays anaccelerator key on the right of the label text, e.g. 'Ctl+S'.It is commonly used in menus to show the keyboard short-cuts for commands.</p><p>The accelerator key to display is not set explicitly.Instead, the <a class="link" href="GtkAccelLabel.html" title="GtkAccelLabel"><span class="type">GtkAccelLabel</span></a> displays the accelerators which have been added toa particular widget. This widget is set by calling<a class="link" href="GtkAccelLabel.html#gtk-accel-label-set-accel-widget"><code class="function">gtk_accel_label_set_accel_widget()</code></a>.</p><p>For example, a <a class="link" href="GtkMenuItem.html" title="GtkMenuItem"><span class="type">GtkMenuItem</span></a> widget may have an accelerator added to emit the"activate" signal when the 'Ctl+S' key combination is pressed.A <a class="link" href="GtkAccelLabel.html" title="GtkAccelLabel"><span class="type">GtkAccelLabel</span></a> is created and added to the <a class="link" href="GtkMenuItem.html" title="GtkMenuItem"><span class="type">GtkMenuItem</span></a>, and<a class="link" href="GtkAccelLabel.html#gtk-accel-label-set-accel-widget"><code class="function">gtk_accel_label_set_accel_widget()</code></a> is called with the <a class="link" href="GtkMenuItem.html" title="GtkMenuItem"><span class="type">GtkMenuItem</span></a> as thesecond argument. The <a class="link" href="GtkAccelLabel.html" title="GtkAccelLabel"><span class="type">GtkAccelLabel</span></a> will now display 'Ctl+S' after its label.</p><p>Note that creating a <a class="link" href="GtkMenuItem.html" title="GtkMenuItem"><span class="type">GtkMenuItem</span></a> with <a class="link" href="GtkMenuItem.html#gtk-menu-item-new-with-label"><code class="function">gtk_menu_item_new_with_label()</code></a> (orone of the similar functions for <a class="link" href="GtkCheckMenuItem.html" title="GtkCheckMenuItem"><span class="type">GtkCheckMenuItem</span></a> and <a class="link" href="GtkRadioMenuItem.html" title="GtkRadioMenuItem"><span class="type">GtkRadioMenuItem</span></a>)automatically adds a <a class="link" href="GtkAccelLabel.html" title="GtkAccelLabel"><span class="type">GtkAccelLabel</span></a> to the <a class="link" href="GtkMenuItem.html" title="GtkMenuItem"><span class="type">GtkMenuItem</span></a> and calls<a class="link" href="GtkAccelLabel.html#gtk-accel-label-set-accel-widget"><code class="function">gtk_accel_label_set_accel_widget()</code></a> to set it up for you.</p><p>A <a class="link" href="GtkAccelLabel.html" title="GtkAccelLabel"><span class="type">GtkAccelLabel</span></a> will only display accelerators which have <code class="literal">GTK_ACCEL_VISIBLE</code>set (see <a class="link" href="gtk-Standard-Enumerations.html#GtkAccelFlags"><span class="type">GtkAccelFlags</span></a>).A <a class="link" href="GtkAccelLabel.html" title="GtkAccelLabel"><span class="type">GtkAccelLabel</span></a> can display multiple accelerators and even signal names,though it is almost always used to display just one accelerator key.</p><div class="example"><a name="id3436873"></a><p class="title"><b>Example 8. Creating a simple menu item with an accelerator key.</b></p><div class="example-contents"><pre class="programlisting"> GtkWidget *save_item; GtkAccelGroup *accel_group; /* Create a GtkAccelGroup and add it to the window. */ accel_group = gtk_accel_group_new (); gtk_window_add_accel_group (GTK_WINDOW (window), accel_group); /* Create the menu item using the convenience function. */ save_item = gtk_menu_item_new_with_label ("Save"); gtk_widget_show (save_item); gtk_container_add (GTK_CONTAINER (menu), save_item); /* Now add the accelerator to the GtkMenuItem.
