public class WRadioButton
extends WAbstractToggleButton

A user control that represents a radio button.

Use a WButtonGroup to group together radio buttons that reflect options that are mutually exclusive.

Usage example:

 enum Vote { Republican, Democrate, NoVote };
 
  // use a group box as widget container for 3 radio buttons, with a title
  WGroupBox container = new WGroupBox("USA elections vote");
 		 
  // use a button group to logically group the 3 options
  WButtonGroup group = new WButtonGroup(this);
 		 
  WRadioButton button;
  button = new WRadioButton("I voted Republican", container);
  new WBreak(container);
  group.addButton(button, Vote.Republican.ordinal());
  button = new WRadioButton("I voted Democrat", container);
  new WBreak(container);
  group.addButton(button, Vote.Democrate.ordinal());
 
  button = new WRadioButton("I didn't vote", container);
  new WBreak(container);
  group.addButton(button, Vote.NoVote.ordinal());
 		 
  group.setCheckedButton(group.button(Vote.NoVote.ordinal()));
