QLable 显示图片

1，各种对就是不显示，因为路径中有其它符号如\n\r什么的

 QStringList FileOpeartion::PathCombine (const QString strPath, QStringList strListTemp)
 {
     QStringList strReturn;

     foreach (const QString &str, strListTemp)
     {
         if (!str.isEmpty())
         {
             strReturn << strPath.trimmed() + str.trimmed();
         }
     }

     return strReturn;
 }

 QPixmap FileOpeartion::GetPicture (QString strPath, int mWidth, int mHeight)
 {
     QPixmap pictureimg;
     //"D:dataFolder/2015/03/15/AIA094/20150315_001402_1024_0094.jpg"

     if (pictureimg.load (strPath))
     {
         pictureimg = pictureimg.scaled (mWidth, mHeight, Qt::KeepAspectRatio);
     }

     return pictureimg;
 }
