I wonder if it would be possible to totally declare the QtQuick scene from C++ without any Qml files actually, with Qt6 you got C++ binding and the Qml is compiled to C++ anyway. Maybe I miss something but it could be possible to actually only write C++ to create the actual scene?!
I would not actually do this myself but it might attract some user that are scare of declarative, I love Qml and the declarative binding make it super easy to glue the model to the GUI and the GUI is not seen into the C++ and my model are stay clean. I find the Qml way to split the layer of the application pretty clean if you understand what you have to do (keep the model and the business logic into C++, Qml is only for the GUI and display). The model exposes property and signal/slot, that it’s doesn’t care where it come from or what is going to modify it. That really force you to have a split between GUI layer and the business logic layer. I stop using QWidgets a few years ago and I don’t miss it a bit, haven’t seen anything I could not achieved into Qml yet, some are a bit trickier than they should but in the end prototyping and modifying the GUI is so quick, I often make the change live when I’m working with my graphic designer and KDAB GammaRay (just need to apply those change after).

While widgets are more powerful and suited for complex desktops applications. This makes me wonder even more why Qt gave up widgets. The logical explanation is, Qt kind of gave up desktop. You explained why the widgets concept is not compatible with the Quick concept. Can you also explain why it was not possible to implement Quick as an additional, mostly widget- independent C++ layer and then wrap it declaratively? -- Best Regards, Bernhard Lindner _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
