GtkAccelLabel
|

<!-- ##### SECTION Short_Description ##### -->
|

A label which displays an accelerator key on the right of the text

<para>
|
|
The #GtkAccelLabel widget is a subclass of #GtkLabel 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.
|
|
</para>
|
|
<para>
|
|
The accelerator key to display is not set explicitly.
|
|
Instead, the #GtkAccelLabel displays the accelerators which have been added to
|
|
a particular widget. This widget is set by calling
|
|
gtk_accel_label_set_accel_widget().
|
|
</para>
|
|
<para>
|
|
For example, a #GtkMenuItem widget may have an accelerator added to emit the
|
|
"activate" signal when the 'Ctl+S' key combination is pressed.
|
|
A #GtkAccelLabel is created and added to the #GtkMenuItem, and
|
|
gtk_accel_label_set_accel_widget() is called with the #GtkMenuItem as the
|
|
second argument. The #GtkAccelLabel will now display 'Ctl+S' after its label.
|
|
</para>
|
|
<para>
|
|
Note that creating a #GtkMenuItem with gtk_menu_item_new_with_label() (or
|
|
one of the similar functions for #GtkCheckMenuItem and #GtkRadioMenuItem)
|
|
automatically adds a #GtkAccelLabel to the #GtkMenuItem and calls
|
|
gtk_accel_label_set_accel_widget() to set it up for you.
|
|
</para>
|
|
<para>
|
|
A #GtkAccelLabel will only display accelerators which have %GTK_ACCEL_VISIBLE
|
|
set (see #GtkAccelFlags).
|
|
A #GtkAccelLabel can display multiple accelerators and even signal names,
|
|
though it is almost always used to display just one accelerator key.

Recreates the string representing the accelerator keys.

accelerators are added or removed from the associated widget.
