autoRepeat | property |
autoRepeat:Boolean[override] | Language Version: | ActionScript 3.0 |
| Product Version: | Flash CS3 |
| Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
A radio button never auto-repeats by definition, so the autoRepeat property is set to
false in the constructor and cannot be changed.
Implementation
override public function get autoRepeat():Boolean override public function set autoRepeat(value:Boolean):voidgroup | property |
group:RadioButtonGroup| Language Version: | ActionScript 3.0 |
| Product Version: | Flash CS3 |
| Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
The RadioButtonGroup object to which this RadioButton belongs.
Implementation
public function get group():RadioButtonGroup public function set group(value:RadioButtonGroup):voidExample ( How to use this example )
The following example demonstrates how to create radio buttons that have different groupings:
import fl.controls.RadioButton;
import fl.controls.RadioButtonGroup;
var rbg1:RadioButtonGroup = new RadioButtonGroup("group1");
var rbg2:RadioButtonGroup = new RadioButtonGroup("group2");
var rb1:RadioButton = new RadioButton();
var rb2:RadioButton = new RadioButton();
var rb3:RadioButton = new RadioButton();
var rb4:RadioButton = new RadioButton();
rb1.group = rbg1;
rb2.group = rbg1;
rb3.group = rbg2;
rb4.group = rbg2;
rb1.move(10,10);

groupName:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flash CS3 |
| Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
The group name for a radio button instance or group. You can use this property to get or set a group name for a radio button instance or for a radio button group.
The default value is "RadioButtonGroup".
Implementation
public function get groupName():String public function set groupName(value:String):voidExample ( How to use this example )
The following example demonstrates how to determine the group name of a radio button that was clicked:

The default value is true.
Implementation
override public function get toggle():Boolean override public function set toggle(value:Boolean):voidThrows
Error — This property cannot be set on the RadioButton.

value | property |
value:Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flash CS3 |

RadioButton | () | Constructor |
public function RadioButton()| Language Version: | ActionScript 3.0 |
| Product Version: | Flash CS3 |
| Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
Creates a new RadioButton component instance.
Method Detail
drawFocus | () | method |
getStyleDefinition | () | method |
public static function getStyleDefinition():Object| Language Version: | ActionScript 3.0 |
| 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.

Example ( How to use this example )
flash.events.Eventproperty 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 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);

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, if mouse locking is disabled. |
localY | The vertical coordinate at which the event occurred relative to the containing sprite, if mouse locking is disabled. |
movementX | The change in horizontal coordinates of the mouse position since the last mouse event, if mouse locking is enabled. |
movementY | The change in vertical coordinates of the mouse position since the last mouse event, if mouse locking is enabled. |

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. |
