event_handler& get_event_handler ( ) [inline, inherited]

The event handler pointer is provided to override the default event handler of a particular widget object without needing to go to the trouble of creating a whole new derived class.

If the event handler is non-null, it will be called instead of handle_event(); if it returns false, then handle_event() will be called as well.
