Could someone please summarize where we are inside this thread? Now I'm completely lost… My summary would be as follows: * We rename QList to QArrayList * We can still discuss whether it should rather be Qt5::QList * QStringList and QBAList will be implemented using QVector * QList becomes an alias to QVector in wip/qt6 (for now at least) * We delay the decision on what QList will be in Qt 6 for a little while * QVector for Qt 6 will most likely be updated with the changes Thiago has waiting since quite some years What is the summary for these? Thiago? * To be able to reach a decision: * we test some Qt libs and apps with QList being an alias to QVector * We know that the only source incompatibility is the stability of references At least the following are source incompatibilities currently (though easily noticeable because they generate compile errors): - QVector doesn’t have to/fromSet, to/fromStdList or (obviously) to/fromVector See https://codereview.qt-project.org/c/qt/qtbase/+/260813 . To/fromVector will be added as deprecated methods in Qt 6. - QVector requires the value type to be default constructible Already fixed , see https://codereview.qt-project.org/c/qt/qtbase/+/242197 Cheers, Lars * If it turns out that most of Qt and (maybe also KDE) run without problems with QList = QVector, we should IMO go down that route. * The reason is that aliasing those classes will resolve many other problems we could otherwise run into Cheers, Lars _______________________________________________ Development mailing list Development@qt-project.org<mailto:Development@qt-project.org> https://lists.qt-project.org/listinfo/development -- Eike Ziller Principal Software Engineer The Qt Company GmbH Rudower Chaussee 13 D-12489 Berlin eike.zil...@qt.io<mailto:eike.zil...@qt.io> http://qt.io<http://qt.io/> Geschäftsführer: Mika Pälsi, Juha Varelius, Mika Harjuaho Sitz der Gesellschaft: Berlin, Registergericht: Amtsgericht Charlottenburg, HRB 144331 B
