Example  ( How to use this example )
The following example creates a new RadioButtonGroup and listens for its change event:
import fl.controls.RadioButton;
import fl.controls.RadioButtonGroup;

var myRadioGroup:RadioButtonGroup = new RadioButtonGroup("options");
myRadioGroup.addEventListener(Event.CHANGE, changeHandler);

var radio1:RadioButton = new RadioButton();
radio1.label = "Option A";
radio1.value = "optionA";
radio1.group = myRadioGroup;
radio1.move(10, 10);
addChild(radio1);

var radio2:RadioButton = new RadioButton();
radio2.label = "Option B";
radio2.value = "optionB";
radio2.group = myRadioGroup;
radio2.move(10, 30);
addChild(radio2);

var radio3:RadioButton = new RadioButton();
radio3.label = "Option C";
radio3.value = "optionC";
radio3.group = myRadioGroup;
radio3.move(10, 50);
addChild(radio3);

function changeHandler(event:Event):void {
    var rbg:RadioButtonGroup = event.target as RadioButtonGroup;
    if (rbg.selectedData != null) {
        trace(rbg.selectedData);
    } else {
        trace("no value specified.");

radioButton:RadioButton — The RadioButton instance to be added to the current radio button group.

getGroup

()method 
public static function getGroup(name:String):RadioButtonGroup

Language Version: ActionScript 3.0

Retrieves a reference to the specified radio button group.

Parameters

name:String — The name of the group for which to retrieve a reference.

Returns
RadioButtonGroup — A reference to the specified RadioButtonGroup.

Example  ( How to use this example )

The following example demonstrates how to determine which radio button in a group is selected:
import fl.controls.RadioButton;
import fl.controls.RadioButtonGroup;

var rbg1:RadioButtonGroup = new RadioButtonGroup("group1");

var rb1:RadioButton = new RadioButton();
rb1.label = "Choice A";
rb1.group = rbg1;
rb1.move(10, 10);
rb1.addEventListener(MouseEvent.CLICK, announceCurrentGroup);
addChild(rb1);

var rb2:RadioButton = new RadioButton();
rb2.label = "Choice B";
rb2.group = rbg1;
rb2.move(10, 30);
rb2.addEventListener(MouseEvent.CLICK, announceCurrentGroup);
addChild(rb2);

function announceCurrentGroup(e:MouseEvent):void {
    var group:RadioButtonGroup = RadioButtonGroup.getGroup("group1");
    trace("The currently selected radio button is: " + group.selection.label);
}

Event Detail

change

Event
Event Object Type: flash.events.Event
property Event.type = flash.events.Event.CHANGE

Language Version: ActionScript 3.0
Product Version: Flash CS3
Runtime Versions: Flash Player 9.0.28.0, AIR 1.0

Dispatched when the selected RadioButton instance in a group changes.

The Event.CHANGE constant defines the value of the type property of a change event object.

This event has the following properties:

PropertyValue
bubblestrue
cancelablefalse; there is no default behavior to cancel.
currentTargetThe object that is actively processing the Event object with an event listener.
targetThe object that has had its value modified. The target is not always the object in the display list that registered the event listener. Use the currentTarget property to access the object in the display list that is currently processing the event.

Example  ( How to use this example )

The following example creates three radio buttons and adds an event listener for a radio button group's change event:
import fl.controls.RadioButton;
import fl.controls.RadioButtonGroup;

var myRadioGroup:RadioButtonGroup = new RadioButtonGroup("options");
myRadioGroup.addEventListener(Event.CHANGE, changeHandler);

var radio1:RadioButton = new RadioButton();
radio1.label = "Option A";
radio1.group = myRadioGroup;
radio1.move(10, 10);
addChild(radio1);

var radio2:RadioButton = new RadioButton();
radio2.label = "Option B";
radio2.group = myRadioGroup;
radio2.move(10, 30);
addChild(radio2);

var radio3:RadioButton = new RadioButton();
radio3.label = "Option C";
radio3.group = myRadioGroup;
radio3.move(10, 50);
addChild(radio3);

function changeHandler(event:Event):void {
    var rg:RadioButtonGroup = event.target as RadioButtonGroup;
    switch (rg.selection) {
        case radio1:
            trace("radio1");
            break;
        case radio2:
            trace("radio2");
            break;
        case radio3:
            trace("radio3");
            break;
    }
}

click

Event  
Event Object Type: flash.events.MouseEvent
property MouseEvent.type = flash.events.MouseEvent.CLICK

Language Version: ActionScript 3.0
Product Version: Flash CS3
Runtime Versions: Flash Player 9.0.28.0, AIR 1.0

Dispatched when a RadioButton instance is clicked.

Defines the value of the type property of a click event object.

This event has the following properties:

PropertyValue
altKeytrue if the Alt key is active (Windows).
bubblestrue
buttonDownFor click events, this value is always false.
cancelablefalse; there is no default behavior to cancel.
commandKeytrue on the Mac if the Command key is active; false if it is inactive. Always false on Windows.
controlKeytrue if the Ctrl or Control key is active; false if it is inactive.
ctrlKeytrue on Windows or Linux if the Ctrl key is active. true on Mac if either the Ctrl key or the Command key is active. Otherwise, false.
currentTargetThe object that is actively processing the Event object with an event listener.
localXThe horizontal coordinate at which the event occurred relative to the containing sprite, if mouse locking is disabled.
localYThe vertical coordinate at which the event occurred relative to the containing sprite, if mouse locking is disabled.
movementXThe change in horizontal coordinates of the mouse position since the last mouse event, if mouse locking is enabled.
movementYThe change in vertical coordinates of the mouse position since the last mouse event, if mouse locking is enabled.
shiftKeytrue if the Shift key is active; false if it is inactive.
stageXThe horizontal coordinate at which the event occurred in global stage coordinates.
stageYThe vertical coordinate at which the event occurred in global stage coordinates.
targetThe InteractiveObject instance under the pointing device. The target is not always the object in the display list that registered the event listener. Use the currentTarget property to access the object in the display list that is currently processing the event.
RadioButtonGroupExample.as

This example demonstrates how to manage many RadioButton objects over several groups
  1. Add the RadioButton and Label components to your library.
  2. Save this code as RadioButtonGroupExample.as in the same directory as your FLA.
  3. Set the DocumentClass in the FLA to RadioButtonGroupExample.
