apache-flex - Flex - Transparent Tree component

Question

I'm using a tree component to show a menu, but I need the background to be transparent.

How can I do this? :) I could make a new "skin" or create a new class (using the old tree) where I remove the background, but I'm not sure how to do this.

Any help would be great!

Thanks,

对不起，我的错..我进行了搜索，发现关于此的信息很少。

将 contentBackgroundAlpha 设置为 0 可以解决问题（在树组件中）。
