Class RadioGroup

java.lang.Object
  |
  +--waba.ui.RadioGroup

public class RadioGroup

extends java.lang.Object

RadioGroup is a Radio control grouper. It handles the click on a radio, unchecking the last selected one.

Use it as:

 RadioGroup rg = new RadioGroup();
 Radio r1 = new Radio("radio 1",rg);
 Radio r2 = new Radio("radio 2",rg);
 Radio r3 = new Radio("radio 3",rg);
 rg.clicked(r1); // activate r1 only
 

Note: there is no need (and you can't) add a RadioGroup to a container, since a RadioGroup is a class that doesn't extend Control.
