To be fair I don't think you completely got what I was trying to say.
I cited the breadcrumb because it's usually visually styled as a group
of buttons (that behave like radios plus some more complicated logic)
grouped together into a "single big button" that contains several
ones. If you look at the screenshots in that link I think it's pretty
clear, I'd like a way to "visually merge" together several buttons
into a grouping container. Look at this mockup too, it should make it
clear enough:

Anyway, I still think that breadcrumb could be a subclass of this
"button group" (a subclass widget *is* more complicated than the
widget it subclasses), but maybe I didn't get the whole breadcrumb
thing.

Well it's not actually the radio functionality that I really care,
that's easily implementable. It's more the custom container that can
be themed to visually merge together several buttons. Once that's
done, the buttons could behave like simple buttons (probably useless),
toggle buttons or radio buttons. They would be just the usual buttons
into a special container probably.

Well, the reason is simple, sexiness. Would you really put radio
buttons into a toolbar?

Hope I was more clear this time,
Cheers,
