Thanks all the same, but some kind soul on OPN #python told me a much 
simpler way, which I post for benefit of others looking for similar.


import new
...

def setevhandler(self, func):
        """
        Assigns a new event handler function to the class (or subclass)
        instance. This provides an alternative to subclassing.
        """
        cls = self.__class__
        if type(func) is not types.FunctionType:
                raise MyNotFunctionError
        self.handleevent = new.instancemethod(func, self, cls)
