Hello,
as per the Qt documentation (
https://doc.qt.io/qt-6/qqmlengine.html#QML_SINGLETON), I'm using a static
`create()` function to inject an existing C++ object as singleton into the
QML runtime.
I'd like to be able to replace that singleton instance over the course of
the application's

Hi Uli,
thank you for sharing that document, that's indeed very helpful.
Following its examples, I was able to set up my singleton such that both
runtimes (C++, QML) would share the same instance.
Doing that I bumped into what I would consider a bug, probably in the MOC
infrastructure:

Hello,
I'm trying to "modernize" a large code base that just migrated from Qt5 to
Qt6.
Our code is using a few singleton objects that used to be exported into the
QML runtime via `qmlRegisterSingletonInstance()`. But as it is now
recommended to move away from `qmlRegisterType()` (in favour of
k, or am I still fundamentally
misunderstanding how to use QML with Qt6 ?

I'm trying to establish a Python test methodology whereby a QApplication is

Hi again,
It looks like the problem is that pyqt5 creates some hidden Qt objects very
early (i.e. upon importing some modules). If I move the imports as well as
the `MainWindow` definition into the secondary thread, everything appears
to be working fine.
