ah, Plasma::Frame isn't actually a QGraphicsProxyWidget. it's just pretending 
to be one; nativeWidget() even just returns 0 ... always.

try putting them in a Plasma::GroupBox instead and see if that works.

*or* create a QButtonGroup, which is a QObject class and allows you to group 
buttons however you'd like. not as elegant as automatically working, but 
should be guaranteed to work =)
