我使用的是Flash Builder 4 Premium。我的应用程序有一个标题栏，但我不想滚动，而标题栏下面的一个组应该滚动。下面是我希望能够滚动的组：

<s:Scroller id="scrlMemberManager" includeIn="MemberManager" y="79" width="100%" height="100%" creationComplete="memberManagerInit()">
    <s:Group id="grpMemberManager">
        <s:Rect top="0" left="0" width="100%" height="100%">
            <s:fill>

            </s:fill>
        </s:Rect>

乍一看，一切都很正常，但是如果你把屏幕做得足够小，直到你需要滚动的地方，背景色就不会填满整个滚动条，而只会填满你开始滚动之前最初显示的部分，所以你会得到如下所示的东西：

我不知道解决这个问题的最佳方法是什么，但我想我可以调整背景颜色矩形的大小以匹配滚动条的宽度......如果我能找出滚动条的宽度是多少的话。（希望我的术语是正确的）。有没有办法找到那个宽度，或者有没有更好的方法来做到这一点？每个面板的宽度都是设置好的，但是窗口的大小可能会延伸到内容的宽度之外，因此我希望确保背景填充用户的窗口（当然不包括标题栏），而不管窗口的大小。
