public delegate void EventListener (Object obj)

A function which is called when an object emits a matching event, as used in add_focus_tracker.

Currently the only events for which object-specific handlers are supported are events of type "focus:". Most clients of ATK will prefer to attach signal handlers for the various ATK signals instead.

see atk_add_focus_tracker.



An Object instance for whom the callback will be called when the specified event (e.g. 'focus:') takes place.
