我有一个带有dataprovider和自定义itemrenderer的s:List。现在我的itemrenderer里面有一个按钮。 每当我从列表中选择一个项目时,我会专注于该项目,但单击该项目中的按钮只会导致s:List选择该项目,并且不会让我按下该项目中的按钮。
是否有任何解决方案可以禁用“列表”选择功能但保持列表中的项目启用/可点击?
根据要求,这里是代码(相关部分)

单击文章ItemRenderer中的按钮元素时会发生错误。应用程序从Categoy.mxml列表中选择“article”-item,而不是单击按钮。
答案 0 :(得分:1)
你需要它作为一个列表吗?它可以只是一个数据组吗? List和DataGroup之间的主要区别在于List具有可选择的项。如果您只是更改代码以使用DataGroup,您仍然可以获得项目渲染器,但是可选性不足。
这样做你需要的吗?
