Most disappointed that most of the good stuff appears to only be available for QtQuick (is that QML?) and not for Widgets.

Hey David,


While Qt Quick (which is QML, indeed) is indeed the primary UI technology for us at this point, most of the new stuff is actually usable for Qt Widget applications as well. For instance:

- CanvasPainter includes a QCanvasPainterWidget, and generally has a comprehensive C++ API
- in StyleKit we explicitly added support for Widgets styling in Qt 6.12
- Qt Graphs works fine in a Widget UI and also has a fairly comprehensive C++ API (i.e. https://doc.qt.io/qt-6.12/qlogvalueaxis.html in 6.12)

Widget applications run fine on HarmonyOS, and QRangeModel specifically works with both Widget and Quick item views.

So, lots of goodness for Widgets users in Qt 6.12, in addition to various smaller additions - mostly contributed by the community - to the Qt Widgets module [1].

Cheers,
Volker
