I used OSF/Motif Release 1.2 without toolbox(XForm.h).
For my project I need to unset a XmToggleButton in radio box.
I try to use XmToggleButtonSetState( ), but doesn`t work.
Therefore, Could you give me a other solution for unset XmToggleButton in radio box like to refresh a Widget or refresh a frame ?

Thanks,
