I can setPixmap the contents of an image file opened via Open. file.BytesAvailable gives me a different value than the number of characters I read from file. Finally, nothing is displayed in the label background.

Qt Code: 
  1. fileContent.clear();
  2.  
  3.     QFile file("://image.jpg");
  4.  
  5.     if(!file.open(QIODevice::ReadOnly)) {
  6.  
  7.         QMessageBox::information(0, "error", file.errorString());
  8.     }
  9.  
  10.     qDebug() << file.bytesAvailable(); //119251 which is equal to file size
  11.  
  12.     QTextStream in(&file);
  13.  
  14.     QString wholeFile = in.readAll();
  15.  
  16.     fileContent.append(wholeFile);
  17.  
  18.     qDebug() << fileContent.length(); //212887 -> not equal to to file size!
  19.  
  20. //    while(!in.atEnd()) {
  21.  
  22. //        QString line = in.readLine();
  23.  
  24. //        fileContent.append(line);
  25. //    }
  26.  
  27.     file.close();
  28.  
  29.     QPixmap px(fileContent.constData());
  30.  
  31.     ui->label->setPixmap(px);
