建構函式

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

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

Creates a new HeaderEvent.

參數

	`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:mx.rpc: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.

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.
