Flex 4 Scroller 组件不渲染水平滚动条
我很确定我的动态 mxml 布局必须给我两个滚动条（水平和垂直），但它只显示垂直一个。 我错过了什么还是它是一个错误？

I'm pretty sure my dynamic mxml layout must give me two scrollbars (horizontal and vertical) but it only shows vertical one.
Am I missing something or is it a bug?

把Scroller里面的VGroup去掉或者改成Group！
使用 VGroup 作为第一个子级时，似乎不显示水平滚动条
Remove the VGroup inside the Scroller or change it to Group!
Seems that the horizontal scrollbar is not shown when using VGroup as first child
您尚未为
Scroller设置horizontalScrollPolicy和verticalScrollPolicy，因此它们的值设置为auto。本例中的行为是仅在必要时才显示滚动条。尝试用
You haven't set
horizontalScrollPolicyandverticalScrollPolicyfor theScrollerand hence they have their value set to theauto. The behavior in this case is to display the scrollbars only if necessary.Try with
