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