示例  ( 如何使用本示例 )
下例创建一个新的 RadioButtonGroup,并侦听其 change 事件:
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.");
    }
}

selection

import fl.controls.RadioButton;
import fl.controls.RadioButtonGroup;

var radioGroup:RadioButtonGroup = new RadioButtonGroup("rbg");
radioGroup.addEventListener(Event.CHANGE, changeHandler);

var radio1:RadioButton = new RadioButton();
radio1.group = radioGroup;

radio1.move(10, 10);
addChild(radio1);

var radio2:RadioButton = new RadioButton();
radio2.group = radioGroup;
radio2.label = "Option B";
radio2.value = 2;
radio2.move(10, 30);
addChild(radio2);

function changeHandler(event:Event):void {

向内部单选按钮数组添加一个单选按钮,以用于单选按钮组索引,这样可允许在单选按钮组中单独选择一个单选按钮。 此方法由单选按钮自动应用,但是也可以手动使用此方法将单选按钮明确添加到组中。

参数

radioButton:RadioButton — 要添加到当前单选按钮组的 RadioButton 实例。

getGroup

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

语言版本: ActionScript 3.0
产品版本: Flash CS3
运行时版本: Flash Player 9.0.28.0, AIR 1.0

检索对指定单选按钮组的引用。

参数

name:String — 要检索对其引用的组的名称。

返回
RadioButtonGroup — 对指定 RadioButtonGroup 的引用。

示例  ( 如何使用本示例 )

下例演示了如何确定组中处于选中状态的单选按钮:
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);
}

getRadioButtonAt

()方法 
public function getRadioButtonAt(index:int):RadioButton

语言版本: ActionScript 3.0
产品版本: Flash CS3
运行时版本: Flash Player 9.0.28.0, AIR 1.0

检索指定索引位置的 RadioButton 组件。

参数

index:int — RadioButtonGroup 组件中的 RadioButton 组件的索引,其中第一个组件的索引为 0。

返回
RadioButton — 指定的 RadioButton 组件。

引发
RangeError — 指定的索引小于 0 或大于等于数据提供程序的长度。

getRadioButtonIndex

()方法 
public function getRadioButtonIndex(radioButton:RadioButton):int

语言版本: ActionScript 3.0
产品版本: Flash CS3
运行时版本: Flash Player 9.0.28.0, AIR 1.0

返回指定 RadioButton 实例的索引。

参数

radioButton:RadioButton — 要在当前 RadioButtonGroup 中查找的 RadioButton 实例。

返回
int — 指定 RadioButton 组件的索引;如果找不到指定 RadioButton,则为 -1。

removeRadioButton

()方法 
public function removeRadioButton(radioButton:RadioButton):void

语言版本: ActionScript 3.0
产品版本: Flash CS3
运行时版本: Flash Player 9.0.28.0, AIR 1.0

从内部单选按钮列表中清除 RadioButton 实例。

参数

radioButton:RadioButton — 要删除的 RadioButton 实例。

事件详细信息

change

事件
事件对象类型: flash.events.Event
属性 Event.type = flash.events.Event.CHANGE

语言版本: ActionScript 3.0
产品版本: Flash CS3
运行时版本: Flash Player 9.0.28.0, AIR 1.0

当组内的选定 RadioButton 实例发生变化时调度。

Event.CHANGE 常量定义 change 事件对象的 type 属性值。

此事件具有以下属性:

属性
bubblestrue
cancelablefalse;没有要取消的默认行为。
currentTarget当前正在使用某个事件侦听器处理 Event 对象的对象。
target已修改其值的对象。target 不一定是显示列表中注册此事件侦听器的对象。请使用 currentTarget 属性来访问显示列表中当前正在处理此事件的对象。

示例  ( 如何使用本示例 )

下例创建三个单选按钮,并为单选按钮组的 change 事件添加一个事件侦听器:
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

事件  
事件对象类型: flash.events.MouseEvent
属性 MouseEvent.type = flash.events.MouseEvent.CLICK

语言版本: ActionScript 3.0
产品版本: Flash CS3
运行时版本: Flash Player 9.0.28.0, AIR 1.0

当单击 RadioButton 实例时调度。

定义 click 事件对象的 type 属性值。

此事件具有以下属性:

属性
altKey如果 Alt 键处于活动状态,则为 true (Windows)。
bubblestrue
buttonDown对于单击事件,此值始终为 false
cancelablefalse;没有要取消的默认行为。
commandKey在 Mac 中,如果 Command 键处于活动状态,则为 true;如果处于非活动状态,则为 false。在 Windows 中始终为 false
controlKey如果 Ctrl 或 Control 键处于活动状态,则为 true,如果处于非活动状态,则为 false
ctrlKey在 Windows 或 Linux 中,如果 Ctrl 键处于活动状态,则为 true。在 Mac 中,如果 Ctrl 键或 Command 键处于活动状态,则为 true。否则为 false
currentTarget当前正在使用某个事件侦听器处理 Event 对象的对象。
localX禁用鼠标锁定时,事件发生点相对于所属 Sprite 的水平坐标。
localY禁用鼠标锁定时,事件发生点相对于所属 Sprite 的垂直坐标。
movementX启用鼠标锁定时,自上一次鼠标事件以来鼠标位置的水平坐标的更改。
movementY启用鼠标锁定时,自上一次鼠标事件以来鼠标位置的垂直坐标的更改。
shiftKey如果 Shift 键处于活动状态,则为 true;如果处于非活动状态,则为 false
stageX事件发生点在全局舞台坐标中的水平坐标。
stageY事件发生点在全局舞台坐标中的垂直坐标。
target指针设备下的 InteractiveObject 实例。target 不一定是显示列表中注册此事件侦听器的对象。请使用 currentTarget 属性来访问显示列表中当前正在处理此事件的对象。
RadioButtonGroupExample.as

此示例演示如何管理跨越若干组的多个 RadioButton 对象。
  1. 将 RadioButton 和 Label 组件添加到库中。
  2. 将该代码作为 RadioButtonGroupExample.as 另存到 FLA 文件所在的同一目录中。
  3. 将 FLA 中的 DocumentClass 设置为 RadioButtonGroupExample。

[ X ]为什么显示为英语?
《ActionScript 3.0 参考》中的内容以英语显示

《ActionScript 3.0 参考》中的部分内容未翻译成所有语言。当某个语言元素未翻译时,将显示为英语。例如,ga.controls.HelpBox 类未翻译成任何语言。因此在简体中文版的参考中,ga.controls.HelpBox 类显示为英语。
