The radio buttons are only to improve the look and feel, as the checkbox
with a tick looks bit awkward the application. Here is the code.

Pl. note that I'm new to GTK programming, so if you find some blunders pl.
excuse me.

Do you really want *radiobuttons* i.e. only one bit being
always set? Anyway, this can be hardly answered without the
code (moreover your description is pretty unclear -- do you
describe the model, the view, or what?).
You have a complete working code sample which sets bits in
some integers using treeview checkbuttons, I sent it in my
first reply (it only misses the hex value representation
part), so compare it with your code.

That's enough.
