virtual bool csGraphics2D::EventHandler::HandleEvent iEvent e  )  [inline, virtual]
 

This is the basic event handling function.

To receive events, a component must implement iEventHandler and register with an event queue using iEventQueue::RegisterListener() and iEventQueue::Subscribe(). The event handler should return true if the event was handled. Returning true prevents the event from being passed along to other event handlers (unless the event's Broadcast flag has been set, in which case it is sent to all subscribers regardless of the return value). If the event was not handled, then false should be returned, in which case other event handlers are given a shot at the event. Do not return true unless you really handled the event and want event dispatch to stop at your handler.

Implements iEventHandler.
