Project created using Python, Qt Designer and PySide2. I hope it helps everyone who is starting now in the Python world. This project works very well with Windows, however on Linux and macOS there are some font size problems and the custom title bar does not work very well.
pip install pyside2==5.15.2PySide2 and PyQt5 in version 5.15.1 are causing problems due to several updates in process.
