Flex / FlashBuilder应用程序中的滚动条围绕内容集？

Question

我在为Flash Builder 4.7构建的应用程序编写滚动屏幕时遇到了一些麻烦。我想编程，所以地图（images / ThirdFloor.png）不会滚动，但描述确实如此（images / FloorThreeGuide.png）。有没有办法做到这一点？或者我只能让整个屏幕滚动？谢谢！

没有滚动条的代码：

    <?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009" 
        xmlns:s="library://ns.adobe.com/flex/spark" title="Level Three">

    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>

    <s:HGroup>
        <!--this is a background image-->
        <s:Image source="images/background.png" height="100%" width="100%">
        </s:Image>
    </s:HGroup>

    <s:VGroup width="100%" height="100%" verticalAlign="top" horizontalAlign="left">
        <!--this tells the app to go back to the main page-->
        <s:Button chromeColor="0x9b063a" label="Home" color="0xffffff" click="navigator.popView()" styleName="back" width="100%" />
        <!--this is the third floor map-->
        <s:Image source="images/ThirdFloor.png"  width="100%" height="100%">
        </s:Image>

<!-- this is the section I want to scroll -->
        <s:Group>
        <!--this is a description for the floor exhibits-->
        <s:Image source="images/FloorThreeGuide.png" width="100%" height="100%">
        </s:Image>
        </s:Group>
    </s:VGroup>
</s:View>

这是代码模拟在设备上播放时的样子 - 点击图片：

您可以将您的论坛包装在一个滚动条中：

<!-- this is the section I want to scroll -->
<s:Scroller>
    <s:Group>
        <!--this is a description for the floor exhibits-->
        <s:Image source="images/FloorThreeGuide.png" width="100%" height="100%">
        </s:Image>
    </s:Group>
<s:Scroller>
