PySide6

PySide6 is the official Python bindings for the Qt 6 application framework. Developed by The Qt Company as part of Qt for Python, PySide6 provides Pythonic access to the Qt 6 APIs, enabling cross‑platform GUI development with Python. It serves as the successor to PySide2 (Qt 5) and aims to offer feature parity with Qt 6 while maintaining a stable, Pythonic API for developers.

PySide6 is distributed under the LGPLv3 with exceptions and a commercial license option, and is published on PyPI as PySide6, allowing installation via pip. It is designed to be used in both open‑source and commercial projects under the terms of the chosen license.

The bindings cover a broad range of Qt modules, including the core QtCore, QtGui, and QtWidgets, as well as QtQml/QtQuick for QML-based UIs and additional modules such as QtNetwork, QtSql, and QtMultimedia. The API supports Qt’s signals and slots mechanism, the event loop, and Qt Designer workflows, providing a Pythonic interface to the underlying C++ libraries.

PySide6 is cross‑platform, running on Windows, macOS, and Linux. It targets Python 3.8 or newer and aligns with the Qt 6 release series, with ongoing maintenance and updates to match Qt’s development cycle.

The project is maintained by The Qt Company with community contributions and comprehensive documentation available through the Qt for Python site. It also includes migration guidance for developers moving from PySide2 to PySide6. Users typically install via PyPI and import modules such as PySide6.QtWidgets to build graphical interfaces.
