good idea.  I'll try it.  Sub-classing the radio button in this case
looks like it won't be too much work, so I'll try that out for practice.

you mean needed in an application?  or needed in a widget library?  I
don't care about having a radio button group with no selected elements.
What I want is a group of related toggle buttons in which one or no
elements may be selected.  I think the usage of such a thing is
intuitive to the user.
