CEikProgressInfo 做的进度条为什么颜色变不了？该怎么解决

CEikProgressInfo 做的进度条为什么颜色变不了？
请问各路高手，进度条的颜色怎么变不了？
代码如下：
  CEikProgressInfo::SInfo info;
info.iHeight = 10;
info.iWidth = 200;
info.iSplitsInBlock = 0;
info.iTextType = EEikProgressTextNone;
info.iFinalValue = 100;

CEikProgressInfo::SLayout layout;
layout.iEmptyColor = KRgbRed;
layout.iFillColor= KRgbYellow;
layout.iEmptyTextColor = KRgbSymbianOrange;
layout.iFillTextColor = KRgbDarkYellow;
layout.iFont = iEikonEnv->NormalFont();

  iPB->new( ELeave ) CEikProgressInfo( info );
  iPB->ConstructL();
  iPB->SetLayout(layout);

像这样的问题.去NOKIA 官方上去问.很容易就搞定了.CSDN热度似乎不够
