- * This interface is presently only meaningful if used on a widget that
- * is (or will be) located inside of a #GtkApplicationWindow and can
- * only be used to associate the widget with actions on that window, or
- * its associated #GtkApplication.
+ * The action will be looked up in action groups that are found among
+ * the widgets ancestors. Most commonly, these will be the actions with
+ * the "win" or "app" prefix that are associated with the #GtkApplicationWindow
+ * or "GtkApplication, but other action groups that are added with
+ * gtk_widget_insert_action_group() will be consulted as well.
