Frequently Asked Questions¶

When did The Qt Company adopt PySide?: In April 2016 The Qt Company decided to properly support the port. For more information, see https://groups.google.com/forum/#!topic/pyside-dev/pqwzngAGLWE.
Why use PySide6 and not PySide, or PySide2?: The PySide Python module was developed for Qt 4 and PySide2 adapts the same for Qt 5. From Qt 6 onwards, the module name changes to PySide6, indicating the Qt version it supports.
Where I can find information about the old PySide project?: The project’s old wiki page is available on PySide, but the project is now deprecated and not supported.

There are three wheels (pyside6, shiboken6, and shiboken6_generator), what’s the difference?

Before the official release, everything was in one big wheel, so it made sense to split these into separate wheels, each for the major projects currently in development:

pyside6: contains all the PySide6 modules to use the Qt framework; also depends on the shiboken6 module.

shiboken6: contains the shiboken6 module with helper functions for PySide6.

shiboken6_generator: contains the generator binary that can work with a C++ project and a typesystem to generate Python bindings. If you want to generate bindings for a Qt/C++ project, there won’t be any linking to the Qt shared libraries; you need to do this by hand. We recommend building PySide6 from scratch to have everything properly linked.

Why is the shiboken6_generator not installed automatically?: It’s not necessary to install the shiboken6_generator to use PySide6. The package is a result of the wheel splitting process. To use the generator, it’s recommended to build it from scratch to have the proper Qt linking.
