apache-flex - Flex SkinnableContainer 作为 HGroup？

Question

我有一个名为“GroupNavCustomContainer”的 SkinnableContainer 类，它使用名为“GroupNavCustomSkin”的 skinClass。GroupNavCustomSkin 是 Fl​​ex 为您创建的默认外观：（Spark SkinnableContainer 容器的默认外观类）。现在，我必须从类外部动态地向 GroupNavCustomContainer 添加按钮，这不是问题。但是，我似乎无法弄清楚如何让我的皮肤表现得像一个 HGroup，所以按钮的间距是均匀的。我试过：修改组容器无济于事：

-->
<!--- @copy spark.components.SkinnableContainer#contentGroup -->
<s:HGroup >

</s:HGroup>

我对 Flex 4.6 还很陌生，所以我确定我在这里遗漏了一个关键概念。

啊，想通了！水平布局与填充结合。我希望有一些关于 Flex Spark 蒙皮的权威指南……
