根据屏幕分辨率动态调整组件大小

[color=darkred][b]将代码写在组件的preInitialize事件监听器里面[/b][/color]
简化案例如下：

		
		
		

	protected function leftContianer_preinitializeHandler(e:FlexEvent):void
	{
		var hg:HGroup=(e.currentTarget) as HGroup;
		if(hg!=null){
			if(Capabilities.screenResolutionX<=1024){
				hg.percentWidth=80;
			}else{
				hg.percentWidth=70;
			}
		}

	}

	protected function rightSpacerContainer_preinitializeHandler(e:FlexEvent):void
	{
		var hg:HGroup=(e.currentTarget) as HGroup;
		if(hg!=null){
			if(Capabilities.screenResolutionX<=1024){
				hg.percentWidth=20;
			}else{
				hg.percentWidth=30;
			}
		}

	}
