Class Gtk.AccelLabel

Import line: Gtk = imports.gi.Gtk;
GIR File: Gtk-3.0.gir
C documentation: GtkAccelLabel
Class : AccelLabel
Implements: Atk.ImplementorIface, Gtk.Buildable
Extends: Gtk.Label
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.
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().
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.
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.
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.

Creating a simple menu item with an accelerator key.

GtkWidget *save_item;
GtkAccelGroup *accel_group;
/* Create a GtkAccelGroup and add it to the window. */
accel_group = gtk_accel_group_new ();
gtk_window_add_accel_group (GTK_WINDOW (window), accel_group);
/* Create the menu item using the convenience function. */
save_item = gtk_menu_item_new_with_label ("Save");
gtk_widget_show (save_item);
gtk_container_add (GTK_CONTAINER (menu), save_item);
/* Now add the accelerator to the GtkMenuItem. Note that since we called
gtk_menu_item_new_with_label() to create the GtkMenuItem the
GtkAccelLabel is automatically set up to display the GtkMenuItem
accelerators. We just need to make sure we use GTK_ACCEL_VISIBLE here. */
gtk_widget_add_accelerator (save_item, "activate", accel_group,
GDK_s, GDK_CONTROL_MASK, GTK_ACCEL_VISIBLE);
