After Qt>=5.9, QWidget addWidget QML ApplicationWindow can cause interface drift. Does anyone know how to solve this problem?

@WoHowLearn
like Ulf Hermann said, use a pure QQuickWidget it should solve the issue for your case

@J-Hilk
It does not working. QWidget cannot addwidget QML Application.
Like this :

@WoHowLearn did you add
QT += quickwidgets
to your project file ? And QQuickWidgets was not imported, as far as I can tell

[WoHowLearn]

@J-Hilk

The program can run,
but there is no way to embed a qquickwidget into a qwidget ,
because the root of QML is ApplicationWindow.

So that's the only way I can do it.

ApplicationWindow

ok, fair enough, what feature of ApplicationWindow is important for you, that you couldn't replace the rootItem with, say a Rectangle?

@J-Hilk
I haven't tried substitution.
But as the QTBUG-67698 last comment says , the exact same code works fine until qt<5.9.
