![]()  | 使用 Flex 4.0 開始,Adobe 建議您使用 spark.effects.AnimateFilter 類別當作是此類別的替代類別。 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.
