--000000000000a9b9cc058aa9365f Content-Type: text/plain; charset="UTF-8" Is *sending* idle events sufficient? I think you have to flush the event queue for the object before it is destroyed (i.e., run its event loop) or else you'll get crashes later when those events are routed to the now-destroyed widget. Something like >>> for event in ???: >>> widget.GetEventHandler().ProcessEvent(event) or whatever???
