Hello,
I don't know why slot is not working...

Qt Code:

  8.     {
  9.         QTimer::singleShot(0, this, SLOT(doTheWork()));
  10.  
  11.         exec();
  12.     }
  13.  
  14. public slots:

  20.         pReply = accessManager.get(QNetworkRequest(QUrl(strUrl)));
  21.         QObject::connect(pReply, SIGNAL(finished()), &eventLoop, SLOT(quit()));
  22.         eventLoop.exec();
  23.  
  24.         QByteArray bData = pReply->readAll();
  25.  
  26.         delete pReply;
  27. qDebug() << "got img";
  28.         emit setLogo(strChannel, bData);
  29.  
  30.         quit(); // not needed ?
  31.     }
  32.
