Good point. File sizes are qint64, so I agree any quantity that is tied to data, not to memory, should either use int or qint64. So, can someone take a look at what it would take to make the models use 64- bit and come up with a proper guide for how to maintain code that compiles and works on both Qt5 and Qt6? The latter is very important: if you can't easily maintain for both, we just add to users' pain. It might be as simple as a typedef added to QAbstractItemModel. Like the q6sizetype typedef that was proposed and I never implemented. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel DPG Cloud Engineering _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
