A radio box is a group of toggle buttons which are considered to be mutually exclusive. That is, only one toggle may be "on" at any one time.
The Radio Box is the preferred way of implementing a one-of-many choice if the number of choices is small.
Radio box is an example of a RowColumn widget and shares the same resource panel.
For more information, consult XmCreateRadioBox(3X) in the OSF/Motif Programmer's Reference.
HINTS
If the number of choices is not small, or screen space is tight, consider using an option menu or list widget.
The toggle buttons in the radio box are gadgets and so will not highlight when selected.
