Constructor Detail

HeaderEvent | () | Constructor

`public function HeaderEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = true, header:Object = null, token:AsyncToken = null, message:IMessage = null)`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Creates a new HeaderEvent.

Parameters

| `type:String` — The event type; indicates the action that caused the event.
| `bubbles:Boolean` (default = `false`)`` — Specifies whether the event can bubble up the display list hierarchy.
| `cancelable:Boolean` (default = `true`)`` — Specifies whether the behavior associated with the event can be prevented. The dfault is `true`, but the `preventDefault()` method has no effect.
| `header:Object` (default = `null`)`` — Object that holds the header of the call.
| `token:AsyncToken` (default = `null`)`` — AsyncToken that represents the call to the method. Used in the asynchronous completion token pattern.
| `message:IMessage` (default = `null`)`` — Source Message of the header.

Method Detail

`public static function createEvent(header:Object, token:AsyncToken, message:IMessage):HeaderEvent`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Utility method to create a new HeaderEvent that doesn't bubble and is cancelable.

Parameters

| `header:Object` — Object that holds the header of the call.
| `token:AsyncToken` — AsyncToken that represents the call to the method. Used in the asynchronous completion token pattern.
| `message:IMessage` — Source Message header.

Returns

| `HeaderEvent` — Returns a new HeaderEvent that doesn't bubble and is cancelable.

toString | () | method |

`override public function toString():String`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Returns a string representation of the HeaderEvent.

Returns

| `String` — String representation of the HeaderEvent.

Constant Detail

HEADER | Constant

`public static const HEADER:String = header`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The HEADER event type.

The properties of the event object have the following values:

Property | Value
--- | ---
`bubbles` | false
`token` | The token that represents the call to the method. Used in the asynchronous completion token pattern.
`cancelable` | true, but the preventDefault() method has no effect.
`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`.
`header` | Header that the RPC call returns in the response.
`message` | The Message associated with this event.
`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.
