+/*  == SENDING EVENTS TO OBJECTS WITH NO WINDOW HANDLE ==
+
+    If the user requested to send the event to a widget with no window,
+    we need to send an event to an object with no hwnd.
+    The way we do that is to send it to the *first* ancestor widget
+    with a window.
+    Then we'll need a way of identifying the child:
+    We'll just keep a list of the most recent events that we have sent,
+    where each entry in the list is identified by a negative value
+    between [-50,-1]. This negative value we will pass on to
+    NotifyWinEvent() as the child id. When the negative value have
+    reached -50, it will wrap around to -1. This seems to be enough
+
+    Now, when the client receives that event, he will first call
+    AccessibleObjectFromEvent() where dwChildID is the special
+    negative value. AccessibleObjectFromEvent does two steps:
+    1. It will first sent a WM_GETOBJECT to the server, asking
+       for the IAccessible interface for the HWND.
+    2. With the IAccessible interface it got hold of it will call
+       acc_getChild where the child id argument is the special
+       negative identifier. In our reimplementation of get_accChild
+       we check for this if the child id is negative. If it is, then
+       we'll look up in our table for the entry that is associated
+       with that value.
+       The entry will then contain a pointer to the QObject /QWidget
+       that we can use to call queryAccessibleInterface() on.
+
+
+    The following figure shows how the interaction between server and
+    client is in the case when the server is sending an event.
+
