Drive your own subclassed widget. In the handle method, call the base class handle method and check the return value: - if it is non-zero, some widget has consumed the event so there is nothing more to do, simply return that value. - if it is zero, no one used the event, so check if it is the event that you are looking for. If so, just use do_callback() or some similar mechanism to invoke the requisite actions. Then return 1 to stop the event from propagating any further (since you have used it.) Something like that ought to work. -- Ian SELEX Sensors and Airborne Systems Limited Registered Office: Sigma House, Christopher Martin Road, Basildon, Essex SS14 3EL A company registered in England & Wales.
