Bool_t HandleEvent(Event_t* ev)

 Handle the event. Returns true if the event has been handled,
 false otherwise.

void SendMessage(const TGWindow* w, Long_t msg, Long_t parm1, Long_t parm2)

 Send message (i.e. event) to window w. Message is encoded in one long
 as message type and up to two long parameters.
