	Event		Summary	Defined By
		contentCreationComplete	Dispatched after the content for this component has been created.	IDeferredContentOwner

Property Detail

creationPolicy

property

creationPolicy:String

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

Content creation policy for this component.

Possible values are:

auto - Automatically create the content immediately before it is needed.
all - Create the content as soon as the parent component is created. This option should only be used as a last resort because it increases startup time and memory usage.
none - Content must be created manually by calling the createDeferredContent() method.

If no creationPolicy is specified for a container, that container inherits the value of its parent's creationPolicy property.

The default value is "auto".

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

deferredContentCreated

property

deferredContentCreated:Boolean [read-only]

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

A flag that indicates whether the deferred content has been created.

Implementation
public function get deferredContentCreated():Boolean

Method Detail

createDeferredContent

()

method

public function createDeferredContent():void

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

Create the content for this component. If the value of the creationPolicy property is auto or all, this the Flex framework calls this method. If the value of the creationPolicy property is none, you must explicitly call this method to create the content for the component.

Event Detail

contentCreationComplete

Event

Event Object Type: mx.events.FlexEvent
property FlexEvent.type = mx.events.FlexEvent.CONTENT_CREATION_COMPLETE

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

Dispatched after the content for this component has been created. With deferred instantiation, the content for a component can be created long after the component is created.

The FlexEvent.CONTENT_CREATION_COMPLETE constant defines the value of the type property of the event object for a contentCreationComplete event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.
