| Herencia | Glow  TweenEffect Effect EventDispatcher Object |
| Versión del lenguaje: | ActionScript 3.0 |
| Versión de producto: | Flex 3 |
| Versiones de motor de ejecución: | Flash Player 9, AIR 1.1 |
 | Desde Flex 4.0, Adobe recomienda la utilización de la clase spark.effects.AnimateFilter como una alternativa a esta clase. In Flex 4, use an AnimateFilter effect with a Glow bitmap filter. |
The Glow effect lets you apply a visual glow effect to a component.
The Glow effect uses the Flash GlowFilter class as part of its implementation. For more information, see the flash.filters.GlowFilter class. If you apply a Glow effect to a component, you cannot apply a GlowFilter or a second Glow effect to the component.
