Referencing frame widgets in another class

[John Salerno]

Hi everyone. I tried posting this question to the gmane newsgroup, but
it's been a while and I don't see it, so it might not be working for
me. I apologize if it appears twice.

My question was about referencing the widgets of my frame from within
a separate class, specifically a validator class. I've tried passing
the frame as an argument to the validator's __init__ method, but I get
an error saying there are too many arguments.

I know this is a very newbie OO question, but I just can't figure it
out! I'm trying to make some kind of reference like this in my
validator class:

frame.widget.method() = some_value

but so far I can't figure out how to get a reference to the frame.

Thanks.
