|  | 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.
