Class for implementing radio button groups.
Example
  • Assume 3 objects of type SimpleCheckBox are placed on the stage, with instance names "tRadio1", "tRadio2", "tRadio3" 
    // create new group, add radio buttons, select first button, listen to change event
var rg:RadioGroup = new RadioGroup();
rg.addButton(tRadio1, "1");
rg.addButton(tRadio2, "2");
rg.addButton(tRadio3, "3");
rg.selectButton(tRadio1);
rg.addEventListener(Event.CHANGE, handleRadioGroupChanged);
          
// create validator, add group for not null validation
mValidator = new Validator();
mValidator.addValidationRule(new NullValidationRule(rg));
    To get the currently selected button, use this: var currentButton:SimpleCheckBox = rg.getSelection() as SimpleCheckBox; To get the value of the currently selected button, use this: var value:* = rg.getValue();
