I just accessed http://root.cern.ch and looked at the tutorials. I've been away from this sort of thing for several years and the old brain is just that 'OLD' ! Well anyway, I'm wondering if I created a root macro for [ buttongroupState.C: A simple example that shows the enabled disabled state ] If I could then turn on the buttons and enable functionality? I'm afraid to try it though with out some expert input though.
