QByteArray to QPixmap

[woodtluk]

Hello everybody

I've a network request that returns a jpeg image. But I get the data as raw QByteArray. How can I convert the QByteArray into a QPixmap?

The requestFinished(QNetworkReply *pReply) slot shown below is connected to the signal void finished(QNetworkReply *) of QNetworkManager.

void NetworkManagement::requestFinished(QNetworkReply *pReply) {
       if (!pReply->error()) {       
 
       // I need the pixmap to show it in a list view (decoration role)
      QPixmap pixmap(pReply->readAll());
 
       // I try to save the pixmap as a jpg file to the disk.
       bool result = pixmap.save("test.jpg", "jpg");
      // This fails, Don't know why.
       Q_ASSERT(result);
     }
}

void NetworkManagement::requestFinished(QNetworkReply *pReply) {
       if (!pReply->error()) {       
       
       // I need the pixmap to show it in a list view (decoration role)
      QPixmap pixmap(pReply->readAll());

       // I try to save the pixmap as a jpg file to the disk.
       bool result = pixmap.save("test.jpg", "jpg");
      // This fails, Don't know why.
       Q_ASSERT(result);
     }
}

Any advice?

Thanks!

You probably need to use QPixmap::loadFromData().
