| Arv | Resize  TweenEffect Effect EventDispatcher Object |
| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
 | Med början från Flex 4.0, rekommenderar Adobe att du använder klassen spark.effects.Resize som ett alternativ till den här klassen. |
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.
