Flex 4 - 如何在复选框和复选框的标签部分周围绘制或放置边框
我对此做了很多研究 - 包括创建自定义皮肤，但似乎无法做到这一点。我只想在复选框和标签周围都有一个边框。我还想要一个背景颜色，我确实通过 opaqueBackground 属性（通过 AS3 设置它）来实现。只是似乎找不到边界的关键。任何帮助表示赞赏。我也需要同样的单选按钮。
I have been doing much research on this - including creating a custom skin but cannot seem to be able to do it. I just want to have one border around both the checkbox and label. I also want a background color which I did manage to via opaqueBackground property (setting it via AS3). Just can't seem to find the key to have a border as well. Any help is appreciated. I need the same for radio buttons as well.

通过创建自定义皮肤，您走上了正确的道路。只需复制默认的 CheckBoxSkin 并在顶层添加一个 矩形，以便首先绘制它（在声明状态的下方和第一个组之前）：
然后将新皮肤设置为复选框皮肤，无论是在 CSS 中还是直接在特定的通过其 SkinClass 进行复选框。
希望有帮助。
You're on the right track by creating a custom skin. Just copy the default CheckBoxSkin and add a Rect at the top level so it gets drawn first (below where the states are declared and before the first Group):
Then set your new skin as the checkbox skin, either in CSS or directly on the specific checkbox via its skinClass.
Hope that helps.
