以前遇到过容器里包容器,并且都要圆角,如果设固定值,这样会失去容器高度 宽度的一致性,今天有时间翻了一下Flex cook,遇到一个方法挺不错.特记下:
<mx:Applicationxmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="createFill()"layout="absolute"><mx:HBox width="400" height="300" cornerRadius="20" id="hbox"/> <mx:Script> <![CDATA[ import flash.net.URLRequest; private var loader:Loader; private function createFill():void { loader = new Loader(); loader.contentLoaderInfo.addEventListener( Event.COMPLETE,completeLoad); loader.load(new URLRequest("../assets/Sunset.jpg")); } private function completeLoad(event:Event):void { var bm:BitmapData = new BitmapData(loader.width, loader.height, true,0x000000); bm.draw(this.loader); var m:Matrix = new Matrix(); m.createBox(this.width/loader.width, hbox.height/loader.height); hbox.graphics.beginBitmapFill(bm, m, true, true); hbox.graphics.drawRoundRectComplex(0, 0, hbox.width, hbox.height, 20, 20, 20, 20); hbox.graphics.endFill(); } ]]> </mx:Script></mx:Application>
