Debugging a C++/QML/Python combo with QtCreator

[bitmap.kid]

Hello, I am developing a C++ Qt/Quick library (libmylib.so) accompanied by a python binding (pymylib.so) generated with the SIP tool. So I use libmylib.so through the pymylib module from a Python script (run.py). I am using a python virtual environment: /home/th/venv/

I want to debug all these in Qt Creator 15.0.1. But this one does not catch the QML code as well as Python.

Here is my run settings :

Python script is launching and debug C++ part is possible. Using native Python distribution (/usr/bin/python) do not solve my problem.

Do I tempt the devil and deviate from the normal use of QtCreator ? I don't find any interesting log information :(
Thank you.

I finally found some more logs from Qtcreator. Just the terminal ones XD
