Use Signals or drawing API instead. Signals do not cover all events but new Signals can be added when needed consider also adding generic signal. However, more interesting and useful is higher level API to create objects, graphics etc. Call event.Skip() in handler to allow default processing in MapWindow. If any error occurs inside of handler, the handler is removed.
