Hi Arno, there has been no further development on making QObjectBindableProperty public, or much work at all when it comes to extending bindable properties and their usage inside Qt. The most substantial feature was an external contribution to support QBindable from non-QProperty based properties, as long as they have a change signal (https://doc.qt.io/qt-6/qbindable.html#QBindable-3).
The main reason why QObjectBindableProperty was never made public is that it is rather easy to shoot oneself in the foot with it, as we discovered in quite a few places inside Qt itself. I think it might be a good idea to have a discussion at Contributor summit where we can talk about the past, present and future of QProperty. I've added it to this year's s program proposal (at https://wiki.qt.io/Qt_Contributor_Summit_2024_-_Program) Kind regards, Fabian ________________________________________ Von: Development <development-boun...@qt-project.org> im Auftrag von Arno Rehn <a.r...@menlosystems.com> Gesendet: Montag, 10.

We'd still like to introduce bindable properties - they're awesome! However, QObjectBindableProperty/QProperty require trivial setters, so that doesn't work for us. Qt uses Q_OBJECT_COMPAT_PROPERTY internally for setters-with-side-effects, but that is private API as of now. I've found notes from Qt CS 2021 indicating that this could be made public in the future [0]. Has there been any development in this direction? If not, is there anything that's blocking this?
