Re: [Interest] Lifetime of QNetworkReply from QNetworkAccessManager
Nothing. But Visual Studio says the QNetworkReply pointer is set to 0xfeeefeee so someone's freeing it. On segunda-feira, 29 de janeiro de 2018 20:06:37 PST Tom Isaacson wrote: > Ah thanks!

Ah thanks! Now I just have to figure out why calling deleteLater() is causing a crash...

[Interest] Lifetime of QNetworkReply from QNetworkAccessManager
If I call a function like QNetworkAccessManager::head() with a QNetworkRequest I get a pointer to a QNetworkReply. But who's responsible for clearing up the QNetworkReply? Is it me, is it parented to the QNetworkReply, is it parented to the QNetworkAccessManager? If the latter, if the QNetworkAccessManager lasts for the lifetime of my application are all the QNetworkReply's going to take memory for the lifetime of the app? I'd expect this to be covered in the documentation but I can't see anything: https://doc.qt.io/qt-5/qnetworkaccessmanager.html#head Thanks, Tom Isaacson ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
