Don't you just love software development?

Yes I did.  Same failure.

Latest version of Python 2.3 under Windows XP w latest

That part doesn't bother me.

Now, I've played around the idea more and I came up
with a version that works in the general case - for
all controls, and in-line with the resource structure
of PythonCard.  See below:

    def addHandler(self, aMethod):
        # Add the Handler to our Handler list.
        if aMethod.name not in self._handlers:
            log.debug("addHandler: " + aMethod.name)
            #self._handlers[aMethod.name] =
event.Handler(aMethod)
            self._handlers[aMethod.name] = aMethod

    def Control_factory(self, attribute,
eventHandlers):
	name=attribute['name']
	for eventName in eventHandlers.keys():
	    eventFct=eventHandlers[eventName]
	    def function(self, background, event):
		if eventFct==None:
		    return None
		return eventFct(self, event)
	    function.name = "on_%s_%s" % (name,eventName)
	    method = new.instancemethod(function, self,
self.__class__)
	    setattr(self, function.name, method)
	    self.addHandler(method)
        self.components[name] = {}
	for key in attribute.keys():
	    self.components[name][key]=attribute[key]
        return function
    

Now, everytime I need to create a control - any kind
of  PythonCard controls, I simply do a:

        # This is my button mouseClick handler
        def on_Button_mouseClick(self, event):
                return

Create a button:

	Control_factory(self, attribute={"type":"Button",
"name":"Button1",
"label":"Button1","position":(5,35)},
eventHandlers={"mouseClick":on_Button_mouseClick})

Notice that the attribute is a standard dictionary no
different from that in the resource file.  

And it works for all controls.  Some form of this
should exist in standard form of PythonCard.
