Activatable widgets can be connected to a Gtk::Action and reflect the state of the action. 
An Activatable can also provide feedback through its action, as it is responsible for activating the related action.
- Since gtkmm 2.16:
This is a utility function for Gtk::Activatable implementors. 
When implementing Gtk::Activatable you must call this when handling changes of the Gtk::Activatable::property_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 Gtk::Activatable->update() method is called when the related Gtk::Action properties change and registers to the action's proxy list.
<note>Be careful to call this before setting the local copy of the Gtk::Action property, since this function uses gtk_activatable_get_action() to retrieve the previous action</note>
