Something like the untested code below will work, without the need to
"exec" anything.

def verifyInteger(x): ...
def verifyFloat(x): ...
verifiers = {"ControlName1": verifyInteger, "ControlName2": verifyFloat, ...}

class MyTextBox(TextBox):
    def __init__(self, controlname, ...):
        self.verifyfunc = verifiers[self.controlname]
        TextBox.__init__(self, ...) 
    ...
    def change(self):
        self.verifyfunc(self.value)
