I'm trying to create an incredibly simple application just to learn gui
programming, but I can't see how to work with radio buttons.
Attached find a simple application that uses radio buttons.
tested on windows XP with
Python version 2.6.3
GTK+ version 2.16.6
pyGTK version 2.12.1
gobject version 2.14.2
cairo version 1.4.12
Used Glade 3.6.1
Hope it works for you and helps answer some of your questions, feel free
to ask questions.
Good luck
