Flex中，进度条的皮肤，以及使用Timer让它自动增加~
mxml中：
<mx:ProgressBar id="proBar"
verticalCenter="0"
horizontalCenter="0"
trackSkin="probar.borderskin"
fontSize="12"
height="24"
color="#336699"
label="正在加载..."
labelPlacement="center"
maskSkin="probar.maskskin"
maximum="100"
direction="right"
mode="manual"
minimum="0"
barSkin="probar.updatedisplay_"
visible="false"
alpha="0.9"> </mx:ProgressBar>
as中：
（注意：没有贴上整个的，只是取了其中相关的）
private var requestDataTimer:Timer = new Timer(50); public function complete():void
{
//register event.
requestDataTimer.addEventListener(TimerEvent.TIMER, progressOnRequestDataTimer);
} private function progressOnRequestDataTimer(event:TimerEvent):void
{
if (progressInt > separateProgressInt)
{
proBar.label = "数据量大或网络慢, 请耐心...";
requestDataTimer.stop();
return;
} proBar.setProgress(progressInt, 100);
proBar.label = "当前进度： " + progressInt.toString() + "%" + "(正在请求数据...)";
progressInt++;
}
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)：
