Release 10.1A: OpenEdge Development:
AppBuilder

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.
