175) How do I unset an XmToggleButton in a radio box? If a radio-

mode toggle button is set and I XtSetValues XmNset a different toggle button,
the first radio button is not automatically unset.  How do can I automatically
unset the first button?

Answer: There are two easy ways to do this.  First, you can set the toggle
with  XmNmenuHistory on the radio box instead of XmNset on the toggle button.
Second, you can use XmToggleButtonSetState() with True for the notify
argument.

Note that some people have reported that XmNmenuHistory correctly sets the
toggle state but the toggle is not always redrawn to show the new state.  This
is a bug in their implementation of Motif.  If you cannot get a patch, you
should use the XmToggleButtonSetState() method.
