CEGUI::BoundSlot Class Reference

Class that tracks a SubscriberSlot, its group, and the Event to which it was subscribed. This is effectively what gets returned from the calls to the Event::subscribe members, though BoundSlot is always wrapped in a reference counted pointer. When a BoundSlot is deleted, the connection is unsubscribed and the SubscriberSlot is deleted. More...
