flex4 设置 圆角

<s:Rect width="100%" height="100%" left="0" top="0" right="0" topLeftRadiusX="3" topRightRadiusX="3" ><s:stroke><s:SolidColorStroke weight="1" /></s:stroke><s:fill> <s:SolidColor color="#4B78C2" color.over="#4B78C2" color.down="#4B78C2"/> </s:fill></s:Rect>

通过设置topLeftRadiusX这个属性可以设置圆角

 

效果如图
