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