Questions tagged [pyside2]

Questions about using PySide2, a Python Qt bindings project for Qt5.

PySide2 was released mid June 2018 as a Technical Preview (supporting Qt 5.11), and it was officially released without the Technical Preview tag, in December 2018 for Qt 5.12.

The project started in May 2015.

Wikipedia:

PySide2 is a Python binding of the cross-platform GUI toolkit Qt, currently developed by The Qt Company under the Qt for Python project. It is one of the alternatives to the standard library package Tkinter. Like Qt, PySide2 is free software. The project started out using Boost.Python from the Boost C++ Libraries for the bindings and later switched to the binding generator Shiboken to reduce the size of the binaries and the memory footprint.

PySide was released under the LGPL in August 2009 by Nokia, the former owners of the Qt toolkit, after Nokia failed to reach an agreement with PyQt developers Riverbank Computing to change its licensing terms to include LGPL as an alternative license.

Work is currently underway to officially launch PySide2 as a Qt product, after all the effort on porting PySide to work with Qt 5.

PySide2 supports Linux/X11, Mac OS X, Windows and Maemo. Support for Android is currently being added by the PySide community.
