  31
  32     This class allows sending unique events via VCL's
  33     Application::PostUserEvent().  When the User-Event is dispatched,
  34     the handler <Event()> is called, which calls the Link provided with
  35     SetEventHdl().
  36
  37     The instances are held via Ref-Count until a possibly sent
  38     event has arrived.  If the target dies before delivery,
  39     the connection must be severed with SetEventHdl(Link()).
