I suppose one could argue that there is some ethical commitment due to the history, but I'm not seeing any commitment in a legal technical sense. I think that after all technical reliance from PyQt is replaced by technical reliance on PySide, the project is free
Key features of the Pyside that are enabled through these drivers include:
- Installing PySide on a Windows SystemPySide 1.2.4
- PySide (free) download Windows version
- Download free PySide 1.0 - FreeDownloadManager.org
- Building PySide on a Windows SystemPySide 1.2.4
- PySide GUI Application Development - DocDroid
- Building PySide on Windows - Qt Wiki
- Pyside and QWS on embedded arm platform
Main difference between these two libraries is in licensing. The free-to-use version of PyQt is licensed under GNU General Public License (GPL) v3 but PySide is licensed under GNU Lesser General Public License (LGPL). This means that PyQt is limited GPL-licensed applications unless you purchase its commercial version, while PySide may be used in non-GPL applications without any additional fee. However, note that both these libraries are separate from Qt itself which also has a free-to-use, open source version and a paid, commercial version.

We've already introduced the Qt Widgets APIwhich is well-suited for building desktop applications. But Qt also provides a declarative API in the form of Qt Quick/QML.Using Qt Quick/QML you have access to the entire Qt framework for building your applications. Your UI consists of two parts: the Python code whichhandles the business logic and the QML which defines the structure and behavior of the UI itself. You can control the UI from Python, or useembedded Javascript code to handle events and animations.Qt Quick/QML is ideally suited for building modern touchscreen interfaces for microcontrollers or device interfaces -- for example, buildinginterfaces for microcontrollers like the Raspberry Pi. However you can also use it on desktop to build completely customized applicationexperiences, like those you find in media player applications like Spotify, or to desktop games.Installation pip install pyqt6 or pip install pyside6A simple Hello World app in PyQt6 with QML. Save the QML file in the same folder as the Python file, and run as normally.main.pymain.qmlpythonimport sysfrom PyQt6.QtGui import QGuiApplicationfrom PyQt6.QtQml
