You want to be using class constructors here, which have the __init__ magic
name. Try something like this:
class Parent:
def __init__(self):
self.button.config(state=NORMAL)
def open_child(self):
kid = Child(self) # pass in a reference to the Parent instance
class Child(Parent):
def __init__(self, parent)
parent.button.config(state=DISABLED)
app = Parent()
I hope that that help. I am not sure if that is what you mean.
Cheers,
Trent
