Submodule QML module not found (MySubmoduleName)

DSpUz

Hello fellow Qt Devs,

I was following this tutorial "QML Modules": https://academy.qt.io/content-details/338477721/2
and ran into the issue where text processor throws an error(which is also visible in the tutorial):

and of course then the methods described in that module do not get highlighted:

however when I build everything runs fine as expected and the submodules contents get loaded and built libraries are there.

Cheers, DSU

Hi,

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 ?

@DSpUz That error comes from the old QML code model.

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

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

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

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.

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

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.
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 ? ...

@JKSH
the QT_QML_OUTPUT_DIRECTORY is setting is not covered in the video tutorial itself, it is only in the github repository, one of the recent rating comments does hint at this:

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.
