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