Another good question to ask when introducing source incompatible changes, is “how hard does it make supporting building with both Qt 5 and Qt 6 from the same code base”. We did that for Qt Creator for quite some while, and it makes the transition process much smoother than doing a big jump with no way back. Not sure what kind of hacks could be done for that specific case (maybe adding a funny custom QObjectTimer class for the Qt 5 build). -- Eike Ziller Principal Software Engineer The Qt Company GmbH Rudower Chaussee 13 D-12489 Berlin eike.zil...@qt.io http://qt.io Geschäftsführer: Mika Pälsi, Juha Varelius, Mika Harjuaho Sitz der Gesellschaft: Berlin, Registergericht: Amtsgericht Charlottenburg, HRB 144331 B _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
