属性详细信息

defaultButton

属性
defaultButton:IButton

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

对原始的默认 Button 控件的引用。当任何控件上有焦点时按 Enter 键可调度 Button 控件上的 click 事件,从而激活 Button 控件,效果与单击鼠标相同。如果将焦点授予了其他 Button 控件,却在当焦点不在按钮上时将焦点切换回原始控件,则默认 Button 控件实际上发生了更改。

此属性由 Flex 容器管理;请勿直接设置此属性来指定默认按钮。

defaultButton 必须属于 mx.controls.Button 类,即使此属性属于 IUIComponent 类型也不例外。



实现
    public function get defaultButton():IButton
    public function set defaultButton(value:IButton):void

defaultButtonEnabled

属性 
defaultButtonEnabled:Boolean

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

一个标志,指示 FocusManager 是否应检查为激活默认按钮而要按下的 Enter 键。TextArea 和希望识别 Enter 键的其他组件将此属性设置为 false,以禁止 Enter 键调度默认按钮上的 click 事件(如果存在)。



实现
    public function get defaultButtonEnabled():Boolean
    public function set defaultButtonEnabled(value:Boolean):void

focusPane

属性 
focusPane:Sprite

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

随着焦点在各容器之间移动的单个 Sprite。Sprite 将作为用于指示组件具有焦点的可视指示符的父项。



实现
    public function get focusPane():Sprite
    public function set focusPane(value:Sprite):void

nextTabIndex

属性 
nextTabIndex:int  [只读]

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

此 Tab 键循环中要用到的下一个唯一的 tab 索引。



实现
    public function get nextTabIndex():int

showFocusIndicator

属性 
showFocusIndicator:Boolean

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

一个标志,指示是否显示用于指示组件具有焦点的指示符。如果为 true,则获得焦点的组件将绘制一个可视指示符,指示它具有焦点。

默认为 false,如果用户使用 Tab 键,则将其设为 true

通常情况下,最好使用 showFocus()hideFocus() 方法更改此属性,因为这些方法还会更新用于指示组件具有焦点的可视指示符。



实现
    public function get showFocusIndicator():Boolean
    public function set showFocusIndicator(value:Boolean):void
方法详细信息

activate

()方法
public function activate():void

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

如果同时有多个 IFocusManagerContainer 可见,则 SystemManager 将激活 FocusManager,然后取消激活。如果在具有已取消激活 FocusManager 的 IFocusManagerContainer 中单击鼠标,则 SystemManager 将对该 FocusManager 调用 activate() 方法。已激活的 FocusManager 将首先调用自身的 deactivate() 方法,然后再激活另一个 FocusManager。

deactivate

()方法 
public function deactivate():void

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

如果同时有多个 IFocusManagerContainer 可见,则 SystemManager 将激活 FocusManager,然后取消激活。如果在具有已取消激活 FocusManager 的 IFocusManagerContainer 中单击鼠标,则 SystemManager 将对该 FocusManager 调用 activate() 方法。已激活的 FocusManager 将首先调用自身的 deactivate() 方法,然后再激活另一个 FocusManager。

findFocusManagerComponent

()方法 
public function findFocusManagerComponent(o:InteractiveObject):IFocusManagerComponent

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

返回包含给定对象(如果有)的 IFocusManagerComponent。因为播放器可以为 Flex 组件的子组件设置焦点,所以此方法可以从组件角度确定具有焦点的 IFocusManagerComponent。

参数

o:InteractiveObject — 具有 Flash Player 级别的焦点的对象。

返回
IFocusManagerComponent — 包含 onull 的 IFOcusManagerComponent

getFocus

()方法 
public function getFocus():IFocusManagerComponent

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

获取当前具有焦点的 IFocusManagerComponent 组件。建议调用此方法而不要使用 Stage 对象,因为此方法可以指示哪个组件具有焦点。Stage 可能会返回该组件中的子组件。

返回
IFocusManagerComponent — 具有焦点的 IFocusManagerComponent 对象。

getNextFocusManagerComponent

()方法 
public function getNextFocusManagerComponent(backward:Boolean = false):IFocusManagerComponent

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

返回 IFocusManagerComponent,当用户按下 Tab 键导航到下一个组件时,它可以获取焦点。如果应用程序中不存在其他的有效组件,则会返回与当前具有焦点的组件相同的组件。

参数

[ 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。
