## Description

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.

Example 1. 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);

## Details

### GtkAccelLabel

    typedef struct _GtkAccelLabel GtkAccelLabel;

The GtkAccelLabel struct contains private data only, and should be accessed using the functions below.

### gtk_accel_label_new ()

    GtkWidget*  gtk_accel_label_new             (const gchar *string);

Creates a new GtkAccelLabel.

`string` : | the label string. Must be non-`NULL`.
Returns : | a new GtkAccelLabel.

### gtk_accel_label_set_accel_closure ()

    void        gtk_accel_label_set_accel_closure
                                                (GtkAccelLabel *accel_label,
                                                 GClosure *accel_closure);

Sets the closure to be monitored by this accelerator label. The closure must be connected to an accelerator group; see `gtk_accel_group_connect()`.

`accel_label` : | a GtkAccelLabel
`accel_closure` : | the closure to monitor for accelerator changes.

### gtk_accel_label_get_accel_widget ()

    GtkWidget*  gtk_accel_label_get_accel_widget
                                                (GtkAccelLabel *accel_label);

Fetches the widget monitored by this accelerator label. See `gtk_accel_label_set_accel_widget()`.

`accel_label` : | a GtkAccelLabel
Returns : | the object monitored by the accelerator label, or `NULL`.

### gtk_accel_label_set_accel_widget ()

    void        gtk_accel_label_set_accel_widget
                                                (GtkAccelLabel *accel_label,
                                                 GtkWidget *accel_widget);

Sets the widget to be monitored by this accelerator label.

`accel_label` : | a GtkAccelLabel
`accel_widget` : | the widget to be monitored.

### gtk_accel_label_get_accel_width ()

    guint       gtk_accel_label_get_accel_width (GtkAccelLabel *accel_label);

Returns the width needed to display the accelerator key(s). This is used by menus to align all of the GtkMenuItem widgets, and shouldn't be needed by applications.

`accel_label` : | a GtkAccelLabel.
Returns : | the width needed to display the accelerator key(s).

### gtk_accel_label_refetch ()

    gboolean    gtk_accel_label_refetch         (GtkAccelLabel *accel_label);

Recreates the string representing the accelerator keys. This should not be needed since the string is automatically updated whenever accelerators are added or removed from the associated widget.

`accel_label` : | a GtkAccelLabel.
Returns : | always returns `FALSE`.

## Property Details

### The "`accel-closure`" property

      "accel-closure"        GClosure              : Read / Write

The closure to be monitored for accelerator changes.

### The "`accel-widget`" property

      "accel-widget"         GtkWidget             : Read / Write

The widget to be monitored for accelerator changes.
