+    Handles a window system event.
+
+    By default this function posts the event on the window system event queue and
+    wakes the Gui event dispatcher. Qt Gui will then handle the event asynchonously
+    at a later point. The return value is not used in asynchronous mode and will
+    always be true.
+
+    In synchronous mode Qt Gui will process the event immediately. The return value
+    indicates if Qt accepted the event.
