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