Toggle buttons

[Jim Parker <hopeye cfl rr com>]

G'Day !

I have an arbitrary number of toolbars  with toggle buttons that vary
dynamically based on the program state.  ( I hope you understand that  ;-)

My problem is that only one toogle button may be active at a given time on
any toolbar.  In other words if the user clicks a toggle button all other
toggle buttons must become inactive.  (The use of a radio button is not an
option)

Is there a way to untoggle a button on any visible toolbar, when another
toggle button is selected ?  Any example code around ?

cheers,
