Can't open .qml file in Design Studio anymore

[coldspark29]

Since I updated the components with Qt maintenance tool, I can't open my .qml file in Design Studio anymore. The button is greyed out. I tried opening the file manually in Design Studio, but then it automatically launches the UI in fullscreen via the qml2puppet. I read here hat you need a .ui.qml file to open it in Design Studio. Not sure if I ever had one. If I did, I probably deleted it somehow.

Did you read https://www.qt.io/blog/qt-creator-6-released ?

The integrated Qt Quick Designer is now disabled by default. Qt Creator will open .ui.qml files in Qt Design Studio. This is a step towards a more integrated workflow between Qt Design Studio and Qt Creator (video). Qt Quick Designer is still there, you can manually enable it again by checking the QmlDesigner plugin in Help > About Plugins.

Thanks! I did not. This solved it at least partly. Is Qt Quick deprecated or why is it disabled by default?

When I open the file in Design Studio now, the UI opens in fullscreen mode with three qml2puppet windows. I can't edit the UI in the form editor. Nothing is visible.

It wasn't like this before.

How can I have it not open the UI? I only want to run it from Qt Creator.

This should restore the old behavior. I don't use this so can't say more.

The behavior is still different. It never opened three qml2puppet windows. I have never seen them before. Guess I need to make this unsolved again...

I think it is related to this old issue

Can I somehow rollback to the old QtCreator with the maintenance tool? This is exremely annoying

Well, guess I have to create a new issue for this.
