- connect(m_netwManager, SIGNAL(finished(QNetworkReply*)), this, SLOT(slot_netwManagerFinished(QNetworkReply*)));
- m_netwManager->get(request);
the slot:
- {
- qDebug() << "Error in" << reply->url() << ":" << reply->errorString();
- return;
- }
- QPixmap pixmap;
- pixmap.loadFromData(jpegData);
- label->setPixmap(pixmap); // or whatever your labels name is
- }
