Flex 4.6一切都可以拖动

Question

我只是让我的itemrenderer（在视图堆中）可拖动，但现在我有以下问题，即我可以在视图堆栈中拖动所有内容。我只想拖动整个itemrenderer或它的一部分（封面）。此时我还可以拖动整个navigatorcontent和滚动条（！）。有人有解决我的问题的方法吗？提前thx！

我想将图像从视图堆栈拖到图像中，这是代码：

<s:HGroup includeIn="Home" x="225" width="310" height="90" gap="30" textAlign="left" verticalAlign="middle"> <s:Image width="100" height="100" source="menu/home.png" click.Home="home_clickHandler(event)"/> <s:Image width="100" height="100" source="menu/fav.png" click.Home="favorites_clickHandler(event)" dragEnter="dragEnterHandler(event)" dragDrop="dragDropHandler(event)"/> <s:Image width="100" height="100" source="menu/cart.png" click.Home="cart_clickHandler(event)"/> </s:HGroup>
