I think if one includes it in the CMake file then it is enough (though i didn't test it), no need to use QML Language Server.

Also your identifier tip solved the other warning, thanks.

@SGaist QtCreator 20.0.1, in this case its Qt 6.11.1 but same error occurs with Qt 6.9.3. I did reset code model same as in video, but that error persists so it doesnt really matter.

The old code model doesn't understand the CMake outputs for the QML modules; no amount of resetting will help. You need to use the new QML Language Server instead.

@JKSH I did enable QML Language Server as you said, and it went from red to yellow :)

Great! That proves that the QML Language Server is active.

Next:

1. Have you built and run your project? You need to build at least once for the module files to be generated for the QML Language Server to see.
2. I see that the tutorial uses a slightly complex folder structure, and sets QT_QML_OUTPUT_DIRECTORY to compensate. Have you done the same?

(Note: Ideally you shouldn't need to set additional fields, but there are currently some limitations in the QML tools. See https://qt-project.atlassian.net/browse/QTBUG-137199 for the nitty gritty details)

Also another warning popped up where it claims QQuickItem doesnt have pressed property for the button:

Yes, that is correct. parent's type is Item. Item has many properties, but pressed is not one of them: https://doc.qt.io/qt-6/qml-qtquick-item.html#properties

I suggest giving an ID to your Button (for example, id: btn) and then write color: btn.pressed ? ...

Please enable the new QML Language Server: https://doc.qt.io/qtcreator/creator-how-to-use-qml-language-server.html

You need to add some details:

• Which version of Qt Creator are you using ?
• Which version of Qt ?
• Did you change any settings related to the code model ?
