ActivatableT.doSetRelatedAction

This is a utility function for #GtkActivatable implementors.

When implementing #GtkActivatable you must call this when handling changes of the #GtkActivatable:related-action, and you must also use this to break references in #GObject->dispose().

This function adds a reference to the currently set related action for you, it also makes sure the #GtkActivatable->update() method is called when the related #GtkAction properties change and registers to the action’s proxy list.

> Be careful to call this before setting the local > copy of the #GtkAction property, since this function uses > gtk_activatable_get_related_action() to retrieve the > previous action.
