Trust me, you are off track.

This code is written to run in the context of the demo app. I'm not
sure where run is defined either. log is some kind of logging object
passed in from the demo. nb is the parent window.

Then you probably need to back up a bit and do some more reading and
experimenting with simple stuff. Do you understand object-oriented
programming in Python? That is kind of a prerequisite.

Keep a reference to the radiobutton and ask it for its state.
