If I understand that right, then you may not want self.varSource at all, 
you could just call self.vsource.GetStringSelection() directly. That 
kind of violates the "Law of Demeter", so an alternative is to make 
self.varSource a property, that gets and sets the Choice selection, that 
way the same data is only stored in one place.

That would look something like this:

def _setVarSource(self, s):
     self.vsource.SetStringSelection(s)

def _getVarSource(self):
     return self.vsource.GetStringSelection()

self.varSource = property(_getVarSource, _setVarSource)


**untested**
