Tk_HandleEvent - invoke event handlers for window system events
Pointer to X event to dispatch to relevant handler(s).
Tk_HandleEvent is a lower-level procedure that deals with window events. It is called by Tk_ServiceEvent (and indirectly by Tk_DoOneEvent), and in a few other cases within Tk. It makes callbacks to any window event handlers (created by calls to Tk_CreateEventHandler) that match eventPtr and then returns. In some cases it may be useful for an application to bypass the Tk event queue and call Tk_HandleEvent directly instead of calling Tk_QueueEvent followed by Tk_ServiceEvent.
This procedure may be invoked recursively. For example, it is possible to invoke Tk_HandleEvent recursively from a handler called by Tk_HandleEvent. This sort of operation is useful in some modal situations, such as when a notifier has been popped up and an application wishes to wait for the user to click a button in the notifier before doing anything else.
