Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 3

Versões de runtime:

Flash Player 9, AIR 1.1

Ao iniciar com Flex 4.0, a Adobe recomenda que você use a classe de spark.effects.Resize como uma alternativa a esta classe.

The Resize effect changes the width, height, or both dimensions of a component over a specified time interval.

If you specify only two of the three values of the widthFrom, widthTo, and widthBy properties, Flex calculates the third. If you specify all three, Flex ignores the widthBy value. If you specify only the widthBy or the widthTo value, the widthFrom property is set to be the object's current width. The same is true for heightFrom, heightTo, and heightBy property values.

If you specify a Resize effect for a resize trigger, and if you do not set the six From, To, and By properties, Flex sets them to create a smooth transition between the object's old size and its new size.

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

  <mx:Resize
    id="ID"
    widthFrom="val"
    heightFrom="val"
    widthTo="val"
    heightTo="val"
    widthBy="val"
    heightBy="val"
    hideChildrenTargets=""
  />
