Class RadioGroupController

  • public class RadioGroupController
extends java.lang.Object
    RadioGroupController is a Radio control grouper. It handles the click on a radio, unchecking the last selected one.

    Use it as: 

     RadioGroupController rg = new RadioGroupController();
 Radio r1 = new Radio("radio 1",rg);
 Radio r2 = new Radio("radio 2",rg);
 Radio r3 = new Radio("radio 3",rg);
 rg.setSelectedItem(r1); // activate r1 only
    Note: there is no need (and you can't) add a RadioGroupController to a container, since a RadioGroupController is a class that doesn't extend Control.
