39  * The #GtkAccelLabel widget is a subclass of #GtkLabel that also displays an
40  * accelerator key on the right of the label text, e.g. “Ctrl+S”.
41  * It is commonly used in menus to show the keyboard short-cuts for commands.
42  * 
43  * The accelerator key to display is typically not set explicitly (although it
44  * can be, with gtk_accel_label_set_accel()). Instead, the #GtkAccelLabel displays
45  * the accelerators which have been added to a particular widget. This widget is
46  * set by calling gtk_accel_label_set_accel_widget().
47  * 
48  * For example, a #GtkMenuItem widget may have an accelerator added to emit
49  * the “activate” signal when the “Ctrl+S” key combination is pressed.
50  * A #GtkAccelLabel is created and added to the #GtkMenuItem, and
51  * gtk_accel_label_set_accel_widget() is called with the #GtkMenuItem as the
52  * second argument. The #GtkAccelLabel will now display “Ctrl+S” after its label.
53  * 
54  * Note that creating a #GtkMenuItem with gtk_menu_item_new_with_label() (or
55  * one of the similar functions for #GtkCheckMenuItem and #GtkRadioMenuItem)
56  * automatically adds a #GtkAccelLabel to the #GtkMenuItem and calls
57  * gtk_accel_label_set_accel_widget() to set it up for you.
58  * 
59  * A #GtkAccelLabel will only display accelerators which have %GTK_ACCEL_VISIBLE
60  * set (see #GtkAccelFlags).
61  * A #GtkAccelLabel can display multiple accelerators and even signal names,
62  * though it is almost always used to display just one accelerator key.
63  *
