You can check this https://www.qt.io/qt-for-python for used to prepare the Python wrappers for Qt and how do you use Qt Creator in Python
Thanks, but this shows how to set up Qt Creator for using the existing Pyside2 bindings and Python environment. My question was how to create my own bindings for my own Qt-based classes.

If you know of any automated tool for generating Python bindings from a C++ Qt class definition, I would like to know about that, not how to use Python inside of Qt Creator. From what I read of the Shiboken2 documentation, using it to generate bindings for anything except trivial classes would be a huge project. I have a library with hundreds of classes and a thousand or more functions. If I have to hand-code a typesystem file for Shiboken -and- keep that up-to-date with any changes I make on the C++ side, it would take me forever.
