Radio-button Sets

The Radio-set widget provides a way to force a single choice from a small set of possibilities. Unlike a logical set that you might construct using Toggle Boxes, a Radio–button Set must always have exactly one member—no more, no fewer—selected. Thus, you cannot use Radio-button Sets when you wish to allow no selection or multiple selection.

The Radio–set widget will represent a value of any standard type, including CHARACTER. Typically, though, you would use a Radio–button Set for values that are basically nontext-numeric, symbolic-in nature.

By default, AppBuilder supplies a set of three buttons, arranged vertically. Using the property sheet, you can easily change the orientation to horizontal, and increase or decrease the number of members in the set.
