public class AddChild
继承AddChild Inheritance OverrideBase Inheritance OnDemandEventDispatcher Inheritance Object

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

AddChild 类将子显示对象(如组件)作为视图状态的一部分添加到容器。可以在 State 类的 overrides 属性中使用该类。可使用 creationPolicy 属性来指定在应用程序启动时还是当您更改到某一视图状态时创建子级。

在子级添加到容器之前,子级不会调度 creationComplete 事件。例如,以下代码在视图状态更改过程中添加 Button 控件。

  <mx:AddChild relativeTo="{v1}">
      <mx:Button id="b0" label="New Button"/>
  </mx:AddChild> 

在前面的示例中,在您更改状态以及 Button 控件被添加到容器之前,Button 控件不调度 creationComplete 事件。如果 AddChild 类同时定义了 Button 和容器(如 Canvas 容器),则 Button 控件将在其创建之后调度 creationComplete 事件。例如,如果 creationPolicy 属性设置为 all,Button 控件将在应用程序启动时调度该事件。如果 creationPolicy 属性设置为 auto,Button 控件将在您更改到视图状态时调度事件。

The <mx:AddChild> tag has the following attributes:

属性详细信息

creationPolicy

属性
creationPolicy:String

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

该子级的创建策略。该属性确定 targetFactory 将在何时创建该子级的实例。仅当指定 targetFactory 属性时,Flex 才使用该属性。以下是有效值:

意义
auto(默认值)在第一次需要实例时创建实例。
all在应用程序启动时创建实例。
none不自动创建实例。必须调用 createInstance() 方法来创建该实例。

默认值为 "auto"。



实现
    public function get creationPolicy():String
    public function set creationPolicy(value:String):void

position

属性 
public var position:String

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

显示列表中子项的位置,随 relativeTo 属性指定的对象而变化。有效值为 "before""after""firstChild""lastChild"

默认值为 "lastChild"。

relativeTo

属性 
public var relativeTo:Object

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

相对于其添加子项的对象。该属性与 position 属性结合使用。此属性是可选的,如果省略此属性,Flex 将使用 State 对象的直接父级,即具有 states 属性的组件,或指定 State 对象的 <mx:states> 标签。

target

属性 
target:DisplayObject

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

要添加的子级。如果设置了该属性,将在应用程序启动时创建子实例。设置该属性等同于设置 targetFactory 属性并将 creationPolicy 设置为 "all"

如果设置了 targetFactory 属性,则不要设置该属性。



实现
    public function get target():DisplayObject
    public function set target(value:DisplayObject):void

targetFactory

属性 
targetFactory:IDeferredInstance

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

创建子级的 factory。可以指定以下任一项目:

  • 实现 IDeferredInstance 接口并创建一个或多个子实例的 factory 类。
  • Flex 组件(即任何为 UIComponent 类的子类的类),如 Button 控件。如果使用 Flex 组件,Flex 编译器会自动将该组件包装到 factory 类中。

如果设置了该属性,子级将在由 creationPolicy 属性确定的时间实例化。

如果设置了 target 属性,则不要设置该属性。该属性是 AddChild 类默认属性。设置该属性并将 creationPolicy 设置为“all 等同于设置 target 属性。



实现
    public function get targetFactory():IDeferredInstance
    public function set targetFactory(value:IDeferredInstance):void
构造函数详细信息

AddChild

()构造函数
public function AddChild(relativeTo:UIComponent = null, target:DisplayObject = null, position:String = "lastChild")

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

构造函数。

参数
relativeTo:UIComponent (default = null) — 相对于添加子项的组件。
 
target:DisplayObject (default = null) — 子对象。所有 Flex 组件都是 DisplayObject 类的子类。
 
position:String (default = "lastChild")target 显示列表中相对于 relativeTo 组件的位置。必须是以下中的一项:“firstChild”、“lastChild”、“before”或“after”。
方法详细信息

apply

()方法
override public function apply(parent:UIComponent):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

应用覆盖。Flex 将保留原始值,以便以后可以在 remove() 方法中恢复该值。

当进入状态时自动调用此方法。不应直接对其进行调用。

参数

parent:UIComponent — 包含此覆盖的状态对象的父级。如果未指定明确目标,覆盖应使用它作为其目标。

createInstance

()方法 
public function createInstance():void

[ 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。
