public void do_set_related_action (Action action)
This is a utility function for Activatable implementors.
When implementing Activatable you must call this when handling changes of the
related_action, and you must also use this to break references in
Object->dispose.
This function adds a reference to the currently set related action for you, it also makes sure the
Activatable->update method is called when the related
Action properties change and registers to the action’s proxy list.
Be careful to call this before setting the local copy of the Action property, since this function uses get_related_action to retrieve the previous action.
