Flex Spark 应用程序容器禁用滚动条
第一个问题，我是否必须有一个应用程序容器作为我的 mxml 文件中的根节点？其次，我在 adobe 网站上阅读此文档，它说Spark 应用程序容器默认没有滚动条，可以通过使用自定义皮肤来添加滚动条。 （查看比较 mx 和 Spark 应用程序容器的表格）。但我的问题是我的应用程序容器默认已经有滚动条，我想摆脱它们。我有一个主应用程序容器，其中包含一个已经有滚动条的自定义子组件。我只希望孩子有滚动条而不是主应用程序。现在我得到了 2 个相互嵌套的滚动条。
First question, do I have to necessarily have a application container as the root node in my mxml file? Second, I was reading this document on adobe's website and it says that the spark application container has no scroll bars by default and they can be added by using a custom skin. (Look at the table comparing the mx and spark application containers). But my problem is that my application container already has scroll bars by default and I want to get rid of them. I have a main application container with a custom child component that already has scroll bars. I just want the child to have the scroll bars and not the main application. Right now I get 2 scroll bars nested within each other.

是的，我已经解决了这个问题。我在 flex4 应用程序组件的外部采用了一个 MX 组件（“Canvas”），并在应用程序标签处找到了启用的滚动条。
Yes I have resolved this problem. I have taken one MX component("Canvas") at outer of flex4 Application component and find out scroll bar enable at application label.
我意识到问题是由控制栏中的水平滑块引起的。如果我从控制栏中删除滑块，容器将按预期工作，这意味着没有滚动条。要解决滚动条中有滑块的问题，只需将其放入水平盒/垂直盒内即可。 （这并不重要，因为滑块是我放入其中的唯一内容），然后禁用封闭框中的水平和垂直滚动条策略。将滑块封装在盒子容器中神奇地解决了这个问题。
I realized that the problem was being caused by having a horizontal slider in my control bar. If I remove the slider from the control bar the container works as expected that means no scroll bars. To solve the problem with having a slider in the scroll bar just put it inside a Hbox / Vbox. (doesn't matter as slider is the only content I put in there) and then disable the horizontal and vertical scroll bar policy on the enclosing box. Enclosing the slider in a box container magically solves the problem.
