* Description:
* This file defines event structures and routines.
*
* History:
* September 26, 1994 Created by Art Lamb
* 05/05/98 art Add Text Services event.
* 07/23/98 kwk Changed UInt16 field in keyDown event to WChar.
* 08/20/98 kwk Split tsmEvent into tsmConfirmEvent & tsmFepButtonEvent.
* 09/07/98 kwk Added EvtPeekEvent routine declaration.
* 10/13/98 kwk Removed EvtPeekEvent until API can be finalized.
* 03/11/99 grant Fixed types of pointers in SysEventType data fields.
* 05/31/99 kwk Added tsmFepModeEvent event.
* 07/14/99 jesse Moved UI structures & constants to Event.h
* defined ranges for future UI & system events.
* 07/30/99 kwk Moved TSM events here from Event.h
* 09/12/99 gap Add new multi-tap implementation
* 09/14/99 gap Removed EvtGetTrapState.
