为了减少Flex文件体积,我们可以使用Release模式编译外,一些资源可以在运行时加载Run-Time-Load(RTL),今天闲逛WEB时,无意发现这个IconUtility类包,很好用,能定义Icon或者Image的source 它的格式如下:
IconUtility.getClass(id,picpath,width,height)
下载:http://lab.benstucki.net/archives/IconUtility.zip
我用一些名车图片做了几个Icon和图片来作为外部资源,结合IconUtilit类写.你可以发挥自己想象，在实际项目中试用一下吧!
效果如下：
Icon.mxml:
view plain copy to clipboard print ? <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" verticalAlign="middle" backgroundColor="0x414141"> <mx:Style> Accordion{ headerStyleName: "mycanvaslTitle"; } .mycanvaslTitle { fontFamily: Arial; fontSize: 12; fontWeight: normal; } </mx:Style> <mx:Script> <!--[CDATA[ import com.benstucki.utilities.IconUtility; ]]--> </mx:Script> <mx:ApplicationControlBar dock="true"> <mx:Label text="Icon与 Image运行时加载实例"/> <mx:Spacer width="100%"/> <mx:Button id="btn1" label="宝马" click="accordion.selectedIndex=0;" icon="{IconUtility.getClass(btn1,'baoma.jpg',32,32)}"/> <mx:Button id="btn2" label="奔驰" click="accordion.selectedIndex=1;" icon="{IconUtility.getClass(btn2,'benchi.jpg',32,32)}"/> <mx:Button id="btn3" label="保时捷" click="accordion.selectedIndex=2;" icon="{IconUtility.getClass(btn3,'bsj.jpg',32,32)}"/> </mx:ApplicationControlBar> <mx:Accordion id="accordion" width="80%" height="100%"> <mx:Canvas id="canvas1" label="宝马车辆" icon="{IconUtility.getClass(canvas1,'baoma.jpg',16,16)}"> <mx:Image id="img1" source="{IconUtility.getClass(img1,'baoma1.jpg',130,126)}"/> </mx:Canvas> <mx:Canvas id="canvas2" label="奔驰车辆" icon="{IconUtility.getClass(canvas2,'benchi.jpg',16,16)}"> <mx:Image id="img2" source="{IconUtility.getClass(img2,'ben1.jpg',130,126)}"/> </mx:Canvas> <mx:Canvas id="canvas3" label="保时捷车辆" icon="{IconUtility.getClass(canvas3,'bsj.jpg',16,16)}"> <mx:Image id="img3" source="{IconUtility.getClass(img3,'bao1.jpg',130,126)}"/> </mx:Canvas> </mx:Accordion> </mx:Application>
