Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1


Starting with Flex 4.0, Apache recommends that you use the spark.effects.SetAction class as an alternative to this class.

The SetPropertyAction class defines an action effect that corresponds to the SetProperty property of a view state definition. You use a SetPropertyAction effect within a transition definition to control when the view state change defined by a SetProperty property occurs during the transition.

MXML SyntaxexpandedHide MXML Syntax

The <mx:SetPropertyAction> tag inherits all of the tag attributes of its superclass, and adds the following tag attributes:

  <mx:SetPropertyAction
    Properties
    id="ID"
    name=""
    value=""
  />
