Property Detail

emphasized

property

emphasized:Boolean

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

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

Method Detail

callLater

()

method

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

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

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.

Parameters

	`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.
