屬性詳細資訊

emphasized

屬性

emphasized:Boolean

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

Draws a thick border around the Button control when the control is in its up state if emphasized is set to true.

實作
public function get emphasized():Boolean
public function set emphasized(value:Boolean):void

方法詳細資訊

callLater

()

方法

public function callLater(method:Function, args:Array = null):void

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

Queues a function to be called later.

Before each update of the screen, Flash Player or AIR calls the set of functions that are scheduled for the update. Sometimes, a function should be called in the next update to allow the rest of the code scheduled for the current update to be executed. Some features, like effects, can cause queued functions to be delayed until the feature completes.

參數

	`method:Function` — Reference to a method to be executed later.

	`args:Array` (default = `null`) — Array of Objects that represent the arguments to pass to the method.
