Actionscript 3 当状态被禁用时，向火花按钮添加翻转状态
我需要为火花按钮的禁用状态添加翻转效果。通过这种方式，用户可以滚动按钮并了解按钮被禁用的原因 我想我必须覆盖ButtonBase的getCurrentSkinState。是否有测试鼠标光标是否位于禁用按钮上的方法Actionscript 3 当状态被禁用时，向火花按钮添加翻转状态,actionscript-3,flex4,flex-spark,Actionscript 3,Flex4,Flex Spark,我需要为火花按钮的禁用状态添加翻转效果。通过这种方式，用户可以滚动按钮并了解按钮被禁用的原因 我想我必须覆盖ButtonBase的getCurrentSkinState。是否有测试鼠标光标是否位于禁用按钮上的方法 谢谢。尝试使用以下方法： package { import spark.components.Button; [SkinState("overDisabled")] public class ButtonWithOverInDisabled extends Button {

[主机组件（“按钮未禁用”）]
希望这有帮助！：） 我试过了，它不起作用。当按钮被禁用时，不会调用getCurrentSkinState。好的，你说得对。现在我已经用real按钮测试了代码，并对其进行了修改。所以现在所需的按钮可以正常工作：）请在您的环境中测试它，并留下您的反馈：）
