Qt Creator Design mode disabled for Qt Quick / PySide6 project

In newly installed Qt Creator 8.0.1, the Design Mode is disabled. I can only code in QML in Edit Mode.

I can easily reproduce the problem by just creating a new Python Qt Quick Project as shown below. The Design Button on the left menu is always disabled.

I tried to add all modules related to the Design Mode with Qt maintenance tool, but it's still disabled. I really get stuck on this configuration problem.

Solution

  • You can enable the QmlDesigner by going to Help > About Plugins... and using the filter to find QmlDesigner. Activate the CheckBox and restart QtCreator.

    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.
