Flex进度条

Flex中，进度条的皮肤，以及使用Timer让它自动增加~

mxml中：

 1 <mx:ProgressBar id="proBar"
 2                     verticalCenter="0"
 3                     horizontalCenter="0"
 4                     trackSkin="probar.borderskin"
 5                     fontSize="12"
 6                     height="24"
 7                     color="#336699"
 8                     label="正在加载..."
 9                     labelPlacement="center"
10                     maskSkin="probar.maskskin"
11                     maximum="100"
12                     direction="right"
13                     mode="manual"
14                     minimum="0"
15                     barSkin="probar.updatedisplay_"
16                     visible="false"
17                     alpha="0.9">
18 
19     </mx:ProgressBar>

as中：

（注意：没有贴上整个的，只是取了其中相关的）

 1 private var requestDataTimer:Timer = new Timer(50);
 2 
 3 public function complete():void
 4 {
 5     //register event.
 6     requestDataTimer.addEventListener(TimerEvent.TIMER, progressOnRequestDataTimer);
 7 }
 8 
 9 private function progressOnRequestDataTimer(event:TimerEvent):void
10 {
11     if (progressInt > separateProgressInt)
12     {
13         proBar.label = "数据量大或网络慢, 请耐心...";
14         requestDataTimer.stop();
15         return;
16     }
17     
18     proBar.setProgress(progressInt, 100);
19     proBar.label = "当前进度： " + progressInt.toString() + "%" + "(正在请求数据...)";
20     progressInt++;
21 }

呵呵，皮肤是在网上找来的(其实本人对flex研究不深，这皮肤里面的弯弯绕绕也没完全看明白，而且感觉flex的每次升级都变动很大，皮肤相关的很多属性都不是以前能用的，导致学习成本都很高啊~所以拿过来修改一番能用就用上了)：
