Hi all,I see that qSort is deprecated in newer versions of Qt. I can also see that std::sort is intended to replace it. But I can't figure out how to use std::sort to sort a QList with a custom compare function. With qSort you could supply your own comparison function to sort however you wanted. I don't see how to do this with std::sort. Do you have to subclass and provide a operator< overload? I'd rather just define a comparison function, is this possible? Thanks, Josh bool variantLessThan(const QVariant &v1, const QVariant &v2) { return v1.toString() < v2.toString(); } qSort(fieldsList.begin(), fieldsList.end(), variantLessThan);
In the above example, just replace qSort with std::sort. It should work. See: https://en.cppreference.com/w/cpp/algorithm/sort Another usage example: https://invent.kde.org/utilities/konsole/-/blob/master/src/profile/ProfileManager.cpp#L186 -- Ahmad Samir _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
