virtual void NLMISC::IEventListener::operator() ( const CEvent & event ) [pure virtual]

Call back of the listener.

Parameters:

event

is the event send to the listener

Implemented in NL3D::CEvent3dMouseListener, CEGUI::NeLRenderer::NeLInputDriver, and NLMISC::CEventListenerAsync.

virtual void NLMISC::IEventListener::process ( const CEvent & event ) [inline, virtual]

Called by CServer::pumpEvent().

The default calls the () operator, unless a hook has been set. In this case processEvent is called on the hook instead (the hook can forward the call to that listener afterwards).
