widget is a subclass of <a class="link" href="class-gtklabel.html" title="gtk.Label"><code class="classname">gtk.Label</code></a> that
displays an accelerator string to the right of the label text, e.g.
<span class="keycap"><strong>Ctrl</strong></span>+<span class="keycap"><strong>S</strong></span>. It is commonly used in menus to show the keyboard
shortcuts for commands. The accelerator string to display is not set
explicitly; instead, the <a class="link" href="class-gtkaccellabel.html" title="gtk.AccelLabel"><code class="classname">gtk.AccelLabel</code></a>
displays the accelerators which have been added to the associated widget. A
widget is associated with the accelerator label by calling <a class="link" href="class-gtkaccellabel.html#method-gtkaccellabel--set-accel-widget" title="gtk.AccelLabel.set_accel_widget"><code class="methodname">set_accel_widget</code>()</a>.</p><p>For example, a <a class="link" href="class-gtkmenuitem.html" title="gtk.MenuItem"><code class="classname">gtk.MenuItem</code></a>
widget may have an accelerator added to emit the "activate" signal when the
<span class="keycap"><strong>Ctrl</strong></span>+<span class="keycap"><strong>S</strong></span> key combination is pressed. A <a class="link" href="class-gtkaccellabel.html" title="gtk.AccelLabel"><code class="classname">gtk.AccelLabel</code></a>
is created and added to the <a class="link" href="class-gtkmenuitem.html" title="gtk.MenuItem"><code class="classname">gtk.MenuItem</code></a>, and
<a class="link" href="class-gtkaccellabel.html#method-gtkaccellabel--set-accel-widget" title="gtk.AccelLabel.set_accel_widget"><code class="methodname">set_accel_widget</code>()</a> is called with the <a class="link" href="class-gtkmenuitem.html" title="gtk.MenuItem"><code class="classname">gtk.MenuItem</code></a> as
the first argument. The <a class="link" href="class-gtkaccellabel.html" title="gtk.AccelLabel"><code class="classname">gtk.AccelLabel</code></a>
will now display <span class="keycap"><strong>Ctrl</strong></span>+<span class="keycap"><strong>S</strong></span> after its label.</p><p>Creating a <a class="link" href="class-gtkmenuitem.html" title="gtk.MenuItem"><code class="classname">gtk.MenuItem</code></a> with
the <a class="link" href="class-gtkmenuitem.html#constructor-gtkmenuitem" title="Constructor"><code class="function">gtk.MenuItem</code>()</a>
function (or one of the similar functions <a class="link" href="class-gtkcheckmenuitem.html#constructor-gtkcheckmenuitem" title="Constructor"><code class="function">gtk.CheckMenuItem</code>()</a>
and <a class="link" href="class-gtkradiomenuitem.html#constructor-gtkradiomenuitem" title="Constructor"><code class="function">gtk.RadioMenuItem</code>()</a>)
and specifying a label, automatically adds a <a class="link" href="class-gtkaccellabel.html" title="gtk.AccelLabel"><code class="classname">gtk.AccelLabel</code></a>
to the <a class="link" href="class-gtkmenuitem.html" title="gtk.MenuItem"><code class="classname">gtk.MenuItem</code></a> and
calls <a class="link" href="class-gtkaccellabel.html#method-gtkaccellabel--set-accel-widget" title="gtk.AccelLabel.set_accel_widget"><code class="methodname">set_accel_widget</code>()</a>
to set it up for you.</p><p>A <a class="link" href="class-gtkaccellabel.html" title="gtk.AccelLabel"><code class="classname">gtk.AccelLabel</code></a>
will only display accelerators which have
<code class="literal">gtk.ACCEL_VISIBLE</code> set. A <a class="link" href="class-gtkaccellabel.html" title="gtk.AccelLabel"><code class="classname">gtk.AccelLabel</code></a>
can display multiple accelerators and even signal names, though it is almost
always used to display just one accelerator.</p><p>The following code fragment creates a simple menu item with an
accelerator and enables the display of the accelerator key string in the
menu item label:</p><div class="example"><a name="id3253816"></a><p class="title"><b>Example 1. Creating a simple menu item with an accelerator key.</b></p><div class="example-contents"><pre class="programlisting">

accel_group = gtk.AccelGroup()
window.add_accel_group(accel_group)
# Create the menu item
save_item = gtk.MenuItem("Save")
save_item.show()
menu.add(save_item)
# Now add the accelerator to the menu item. Note that since we created
# the menu item with a label the AccelLabel is automatically setup to
# display the accelerators.
save_item.add_accelerator("activate", accel_group, ord("S"),
gtk.gdk.CONTROL_MASK, gtk.ACCEL_VISIBLE)
