| 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.AnimateFilter como uma alternativa a esta classe. 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.
