Well, you don't tell me how {INFO} is defined,
but if it is not defined with an ID, TOP, and HANDLER
field, then it is likely this event is being swallowed
in the event handler of the self.group_leader widget.
Is that the event handler that is suppose to do something
sensible with this event?
Just too many unknowns here for me to make sensible
judgments. Maybe you want to send this event to the
draw widget?
Cheers,
David
