| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
 | A partire da Flex 4.0, Adobe consiglia di utilizzare la classe spark.effects.SetAction come alternativa a questa classe. |
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.

Captures the current values of the relevant properties
on the effect's targets and saves them as end values. | Effect | |
|
Captures the current values of the relevant properties
of an additional set of targets
Flex uses this function when a data change
effect is run.

on the effect's targets. | Effect | |
|
Creates a single effect instance and initializes it. | Effect | |

Takes an Array of target objects and invokes the
createInstance() method on each target. | Effect | |
