<div class="refsect1" title="Description">
<a name="GtkAccelLabel.description"></a><h2>Description</h2>
<p>
The <a class="link" href="GtkAccelLabel.html" title="GtkAccelLabel"><span class="type">GtkAccelLabel</span></a> widget is a subclass of <a class="link" href="GtkLabel.html" title="GtkLabel"><span class="type">GtkLabel</span></a> that also displays an
accelerator 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 to
a particular widget. This widget is set by calling
<a class="link" href="GtkAccelLabel.html#gtk-accel-label-set-accel-widget" title="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" title="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 the
second 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" title="gtk_menu_item_new_with_label ()"><code class="function">gtk_menu_item_new_with_label()</code></a> (or
one of the similar functions for <a class="link" href="gtk-gtkcheckmenuitem.html#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" title="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" title="enum 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.

This is used by menus to align all of the <a class="link" href="GtkMenuItem.html" title="GtkMenuItem"><span class="type">GtkMenuItem</span></a> widgets, and shouldn't
be needed by applications.
