Hello everyone. I'm trying to make this code works http://www.bogotobogo.com/Qt/Qt5_Downloading_Files_QNetworkAccessManager_QNetworkRequest.php I'm put a qDebug() << "running"; inside the slot to test. But the slot "**replyFinished **" is never called. The only difference is the main function that i'm not using. The below code is inside another method, and works. Downloader d; d.doDownload(); What is wrong?! Thanks in advance!

How can you create an instance on the heap? Just as with any other c++ class: with the new keyword. Downloader* d = new Downloader(); d->doDownload(); but that is leaking memory, so you need to make sure the downloader is deleted when it finishes. You could, for example, emit a signal when it's done: class Downloader : public QObject { ... signals: void finished() const; ... Emit it in the replyFinished() : void Downloader::replyFinished (QNetworkReply *reply) { ... reply->deleteLater(); emit finished(); } and then you can use it like this: void someFunction() { Downloader* d = new Downloader(); d->doDownload(); connect(d, &Downloader::finished, d, &Downloader::deleteLater); }
