You might want to read these CppCon17 slides, "Effective Qt: 2017 edition" by Giuseppe D'Angelo (KDAB) https://github.com/CppCon/CppCon2017/blob/master/Presentations/Effective%20Qt%20-%202017%20Edition/Effective%20Qt%20-%202017%20Edition%20-%20Giuseppe%20D'Angelo%20-%20CppCon%202017.pdf It's full of interesting information, like: - Don't use Qt container, unless you have to - Do not use QList, prefer QVector.
