Radio (filter, event)
Unites those descendants that are Choice components into
``radio buttons.'' Within a Radio, at most one Choice component is
selected at any given time.
- Value
- (Symbol, "")
The name of the Choice
element currently selected. Note that the application can clear
the selection, so that no member of the group is selected, but
the user cannot. The current selection can be accessed via
FormsVBT.GetChoice and FormsVBT.PutChoice.
- Behavior
- An event is generated whenever the user changes which element
of the group is selected. If the Choice element has an attached
event procedure, it will be called; otherwise, the event falls through
to the Radio group, which may also have an attached procedure. Thus
an event can occur in the name of the Radio group, though the group
itself has no interactive behavior.
- Shape
- The shape of its child.
