Indicates whether a radio button is currently selected (true) or deselected (false).
You can only set this value to true; setting it to false has no effect. To
achieve the desired effect, select a different radio button in the same radio button group.
The default value is false.

A radio button is a toggle button; its toggle property is set to
true in the constructor and cannot be changed.
The default value is true.

Creates a new RadioButton component instance.

| Product Version: | Flash CS3 |
| Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
Retrieves the default style map for the current component. The style map contains
the type that is appropriate for the component, depending on the style that
the component uses. For example, the disabledTextFormat style
contains a value of null or a TextFormat object.
You can use these styles and call setStyle() on the current
component. The following code overrides the default disabledTextFormat
style on the specified component:
componentInstance.setStyle("disabledTextFormat", new TextFormat());Object — Default styles object.

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 radio button instance's selected property changes.
Event.CHANGE constant defines the value of the type property of a change event object.
This event has the following properties:
| Property | Value |
|---|---|
bubbles | true |
cancelable | false; there is no default behavior to cancel. |
currentTarget | The object that is actively processing the Event object with an event listener. |
target | The 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 RadioButton component instances and listens for the
click and change events:
import fl.controls.RadioButton;
var radio1:RadioButton = new RadioButton();
radio1.label = "Option A";
radio1.move(10, 10);
radio1.addEventListener(MouseEvent.CLICK, clickHandler);
radio1.addEventListener(Event.CHANGE, changeHandler);
addChild(radio1);
var radio2:RadioButton = new RadioButton();
radio2.label = "Option B";
radio2.move(10, 30);
radio2.addEventListener(MouseEvent.CLICK, clickHandler);
radio2.addEventListener(Event.CHANGE, changeHandler);
addChild(radio2);
var radio3:RadioButton = new RadioButton();
radio3.label = "Option C";
radio3.move(10, 50);
radio3.addEventListener(MouseEvent.CLICK, clickHandler);
radio3.addEventListener(Event.CHANGE, changeHandler);
addChild(radio3);
function clickHandler(event:MouseEvent):void {
trace("click:", event.currentTarget.label);
}

| Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
Dispatched when the user clicks the radio button with the mouse or spacebar.
Defines the value of thetype property of a click event object.
This event has the following properties:
| Property | Value |
|---|---|
altKey | true if the Alt key is active (Windows). |
bubbles | true |
buttonDown | For click events, this value is always false. |
cancelable | false; there is no default behavior to cancel. |
commandKey | true on the Mac if the Command key is active; false if it is inactive. Always false on Windows. |
controlKey | true if the Ctrl or Control key is active; false if it is inactive. |
ctrlKey | true 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. |
currentTarget | The object that is actively processing the Event object with an event listener. |
localX | The horizontal coordinate at which the event occurred relative to the containing sprite. |
localY | The vertical coordinate at which the event occurred relative to the containing sprite. |
shiftKey | true if the Shift key is active; false if it is inactive. |
stageX | The horizontal coordinate at which the event occurred in global stage coordinates. |
stageY | The vertical coordinate at which the event occurred in global stage coordinates. |
target | The 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. |

radio1.addEventListener(MouseEvent.CLICK, clickHandler);
