Class Struggle: Connecting a Method to an Outside Variable

[vulpesVelox]

You want the bind() method:

myVar.bind('Button-1', myMethod)

I've tried to insert your suggestion in a couple of different ways now, but all attempts result in either:

NameError: name 'myVar' is not defined
or:
NameError: name 'label_1' is not defined

I did a bit of reading on the subject, and it turns out that 'Button-1' is a fixed expression within the realm of the bind method, hence it wont bind to a label or a text field or any object which is not a button in tkinter. - Right?

Thank you all the same; now I know there's a method called bind. Any type of progress is good progress :)

For clarity, here's version 1 (without using classes). This one works just fine.
