@GrecKo said in Autocompletion Not Working in QML for C++ Instances:
Don't use setContextProperty to expose your C++ instances.

Okay. Thank you. I've been through those several times and am still rereading and rereading them trying to get a complete understanding of them. I notice they use a pro file to add the components so I'll have to convert that to cmake terms.
I'm new to using Qt6 and the last time I used Qt5 was a few years ago so a lot has changed mainly the use of cmake instead of a pro file which is fine with me and I want to learn to use the cmake build process.
I've been trying to find the "right way" to do this but there seems to be a lot of conflicting posts out there and unfortunately I think many still fall back on the Qt5 processes which may work but don't help someone trying to find the Qt6 way! I use the QObject and QML_ELEMENT and QML_PROPERTY in my classes as well as including the qml registration header. So any help is appreciated.
I have a CMakeLists.txt in my project main which adds a subdirectory for utils in which I have a CMakeLists.txt that creates a static library and adds a qml module which is then linked in the main CMakeList.txt All of this is based on the blog post for Qt6 about the new modules . I assume I still need to include the Q_IMPORT_QML_PLUGIN(utilsPl,ugin) in main.cpp. Is this correct?
Then if I am correct I can use the import utils (the module URI) in my QML modules?
The Qt documentation is much better then most for sure but sometimes I feel since they know the process they use partial examples and leave out what is obvious to them. I'd love a blog on how to create a project from scratch with subdirectories, adding the libraries, and then integrating a sample C++ property and function into QML and include all the steps to do setup in main.cpp and any QML modules and of course a sample going the other way!f
