        self.endButton(self.lijn_window)
        self.finish(self.lijn_window)
main(None)

you know you can do single line comments like # so - instead of ''' comment ''' ? — Alex Coplan

@Alex, he's doing it right. Strings in that position become the function's help text ("docstring"). — alexis

When you link the commands, do it without the () so command=self.action, like this. Also this line seems to be giving you some trouble self.quitAll()... not sure what your trying to do with it but that's my two cents.
