- * @See_also: #GtkItemFactory, #GtkAccelGroup
+ * @See_also: #GtkAccelGroup
*
* 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'.
* GtkAccelLabel is automatically set up to display the GtkMenuItem
* accelerators. We just need to make sure we use GTK_ACCEL_VISIBLE here. *<!---->/
