I did some benchmarking (as we were worried about the different performance characteristics of QList and QVector) and with the exception of prepending in a loop pretty much all other operations gets faster with this change.
Another exception is certainly the sorting of large objects that are not implicit-shared classes. Ok anyway. But keeping the old QList under a new name, cannot harm. Much of Qt was built with QList, so QList can't be that bad ;) Philippe On Fri, 2 Nov 2018 07:51:22 +0000 Lars Knoll <lars.kn...@qt.io> wrote: Renaming the subthread (its got nothing to do with build systems ) > > > I believe I have a solution to get rid of QList without breaking SC in any > major way.
