	I'd have to see /how/ it is called. The "button click" is an event
handled by the GUI framework, to which you've bound a handler. Such items
(which may be attached to resize, menu, text fields, etc.) would need the
structure the framework uses... So if a method of a class, that means a
first argument placeholder of "self", and most likely a second for some
"event" data structure. You'd have to check the documentation for what it
expects.

	callback by framework:	theButton.pressed((clock, x, y))
		defined as:				def pressed(self, event):
	(granted, having the mouse x/y coordinates may not mean much for a
screen button)

	callback by framework:	mouseHandler.move((clock, x, y, lmb, rmb, mmb))
		defined as:				def move(self, event):
	(xmb is left/right/middle mouse button state)


	But if it is not being called by the framework, the arrangement/number
of arguments is under your control. If it is a method of a class instance,
it will receive the instance object as the first argument:
object.method(arglist) => method(self, arglist) {where self IS object}.
