Flex自适应浏览器大小

当浏览器大小变化（拖到改变大小或者F11时），应用能够自动实用浏览器大小的改变。部分代码如下：

    <fx:Script>
        <![CDATA[
            
            import mx.events.FlexEvent;
            import mx.events.ResizeEvent;
                        
            protected function vgroup1_creationCompleteHandler(event:FlexEvent):void
            {
                this.imageList.width = screen.width;
                this.addEventListener(ResizeEvent.RESIZE,update);
            }
            
            public function update(e:ResizeEvent):void
            {
                this.imageList.width = screen.width;
            }
            
        ]]>
    </fx:Script>
