The AddChild class adds a child display object, such as a component, to a container as part of a view state. You use this class in the overrides property of the State class. Use the creationPolicy property to specify to create the child at application startup or when you change to a view state.

The child does not dispatch the creationComplete event until it is added to a container. For example, the following code adds a Button control as part of a view state change:

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

In the previous example, the Button control does not dispatch the creationComplete event until you change state and the Button control is added to a container. If the AddChild class defines both the Button and a container, such as a Canvas container, then the Button control dispatches the creationComplete event when it is created. For example, if the creationPolicy property is set to all, the Button control dispatches the event at application startup. If the creationPolicy property is set to auto, the Button control dispatches the event when you change to the view state.

속성 세부 정보

creationPolicy

속성

creationPolicy:String

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

The creation policy for this child. This property determines when the targetFactory will create the instance of the child. Flex uses this properthy only if you specify a targetFactory property. The following values are valid:

Value	Meaning
`auto`	(default)Create the instance the first time it is needed.
`all`	Create the instance when the application started up.
`none`	Do not automatically create the instance. You must call the `createInstance()` method to create the instance.

기본값: "auto".

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

position

속성

public var position:String

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

The position of the child in the display list, relative to the object specified by the relativeTo property. Valid values are "before", "after", "firstChild", and "lastChild".

기본값: "lastChild".

relativeTo

속성

public var relativeTo:Object

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

The object relative to which the child is added. This property is used in conjunction with the position property. This property is optional; if you omit it, Flex uses the immediate parent of the State object, that is, the component that has the states property, or <mx:states>tag that specifies the State object.

target

속성

target:DisplayObject

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

The child to be added. If you set this property, the child instance is created at app startup. Setting this property is equivalent to setting a targetFactory property with a creationPolicy of "all".

Do not set this property if you set the targetFactory property.

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

targetFactory

속성

targetFactory:IDeferredInstance

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

The factory that creates the child. You can specify either of the following items:

A factory class that implements the IDeferredInstance interface and creates the child instance or instances.
A Flex component, (that is, any class that is a subclass of the UIComponent class), such as the Button contol. If you use a Flex component, the Flex compiler automatically wraps the component in a factory class.

If you set this property, the child is instantiated at the time determined by the creationPolicy property.

Do not set this property if you set the target property. This propety is the AddChild class default property. Setting this property with a creationPolicy of "all" is equivalent to setting a target property.

구현
public function get targetFactory():IDeferredInstance
public function set targetFactory(value:IDeferredInstance):void

Constructor.

매개 변수

	`relativeTo:UIComponent` (default = `null`) — The component relative to which child is added.

	`target:DisplayObject` (default = `null`) — The child object. All Flex components are subclasses of the DisplayObject class.

	`position:String` (default = "`lastChild`") — the location in the display list of the `target` relative to the `relativeTo` component. Must be one of the following: "firstChild", "lastChild", "before" or "after".

override public function apply(parent:UIComponent):void

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Applies the override. Flex retains the original value, so that it can restore the value later in the remove() method.

This method is called automatically when the state is entered. It should not be called directly.

매개 변수

parent:UIComponent — The parent of the state object containing this override. The override should use this as its target if an explicit target was not specified.

createInstance

()

메서드

public function createInstance():void

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

Creates the child instance from the factory. You must use this method only if you specify a targetFactory property and a creationPolicy value of "none". Flex automatically calls this method if the creationPolicy property value is "auto" or "all". If you call this method multiple times, the child instance is created only on the first call.

initialize

()

메서드

override public function initialize():void

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

IOverride interface method; this class implements it as an empty method.

remove

()

메서드

override public function remove(parent:UIComponent):void

언어 버전:

ActionScript 3.0

제품 버전:

Removes the override. The value remembered in the apply() method is restored.

This method is called automatically when the state is entered. It should not be called directly.

매개 변수

parent:UIComponent — The parent of the state object containing this override. The override should use this as its target if an explicit target was not specified.
