Detailed Description

Base class for event listeners.

The event listeners handleEvent() method is called when an event is notified via the MCEvent::notify() method. The handleEvent method is guaranteed to be called once per call to the notify() method. It is safe to call the static MCEvent methods dealing with event and listener registration while in the handleEvent method.

Member Function Documentation

virtual void handleEvent (  const MCEvent &  event  )  [pure virtual]

Interface to EventListeners. The implementation must override the handleEvent function. The framework calls handleEvent with the event that occured. The event may contain additional data other than the event id. Because a single listener may be registered for different events, it is recommended that the handleEvent() method obtains the eventId from the event before deciding what action to take. The static MCEvent methods dealing with event registration and listener add/remove can be safely called from the handleEvent() method. Parameters: event  the event which occured
