virtual bool handleEvent (  const Event &  event  )  [inline, virtual]

Callback function that is implemented by the callee. Parameters: event  specifies the time of the event. Event time will be the same for events occurring in the same render phase For example, PREUPDATE, POSTUPDATE, PRERENDER and POSTRENDER event callbacks will all pass the same event time for the same frame. Returning stop Emma from calling the rest of the handlers for this event If you return true, Emma will keep on calling rest of the handlers for this event Implements EventHandler. Reimplemented in ButtonSensor, ValueSensor, and WindowSensor.
