==Qt for Python==
The '''Qt for Python''' project aims to provide a complete port of the [[PySide]] module to Qt 5. The development started on [https://github.com/PySide GitHub] in May 2015. The project managed to port Pyside to Qt 5.3, 5.4 & 5.5. During April 2016 The Qt Company decided to properly support the port (see [https://groups.google.com/forum/#!topic/pyside-dev/pqwzngAGLWE details] ).

During April 2016 The Qt Company decided to properly support the port (see [https://groups.google.com/forum/#!topic/pyside-dev/pqwzngAGLWE details] ).
 
The module 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.
In December 2020, the module was released for Qt6, which is the latest available version, which has the following differences:
 
*It doesn't support Python 2.7,
*Dropped support for Python 3.5, keeping 3.6+ only until PySide 6.3
*PySide 6.4 is the first version that supports Python 3.7+

* Q: PySide? Qt for Python? what is the name?
==Contributing to the Qt for Python Wiki==
** A: The name of the project is '''Qt for Python''' and the name of the module is '''PySide2'''.
* Q: Why PySide2 and not just PySide?
** A: Since PySide was developed for Qt4, when the port was made to support Qt5, the name was change to PySide2 to infer that is was a newer version.
* Q: Where I can find information about the old PySide project?
** A: The old wiki page of the project is available on [[PySide]], '''but''' the project is deprecated, and there is no official support for it. We highly recommend to not use it.
* Q: My project is using PySide, how hard would it be to adapt it to PySide2?
** A: The changes are the same between [https://doc.qt.io/qt-5/qt5-intro.html Qt4 and Qt5], and for PySide users means mostly on adapting the ''import'' statement, since many classes were moved from QtGui to QtWidgets.
::''Qt 5 is highly compatible with Qt 4. It is possible for developers of Qt 4 applications to seamlessly move on to Qt 5 with their current functionality and gradually develop new things leveraging all the great items Qt 5 makes possible.

Qt for Python

Qt for Python official logo.

The Qt for Python project aims to provide a complete port of the PySide module to Qt. The development started on GitHub in May 2015. The project managed to port PySide to Qt 5.3, 5.4 & 5.5. During April 2016 The Qt Company decided to properly support the port (see details ).

The module 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. In December 2020, the module was released for Qt6, which is the latest available version, which has the following differences:

  • It doesn't support Python 2.7,
  • Dropped support for Python 3.5, keeping 3.6+ only until PySide 6.3
  • PySide 6.4 is the first version that supports Python 3.7+

This wiki page tracks the progress of the Qt for Python project development and provides further information concerning the effort.

Qt for Python is available under LGPLv3/GPLv2 and commercial license for the following platforms:

Linux macOS Windows
i386 amd64 arm64 32bit 64bit Apple Silicon 32bit 64bit
Python 3.7+ ✸ ⁜ ✸ ⦿ ✸ ✦
  • ⁜ Partially supported via cross compilation
  • ✸ No Qt Support https://doc.qt.io/qt-6/supported-platforms.html
  • ☆ Not supported / No packages
  • ⦿ Supported from 6.2.2 / Can be built from source
  • ✦: 5.14 is the first version to support Python 3.8, but Python 3.8.0 will not work on Windows. Please use Python 3.8.1 or greater.
  • Please notice that iOS, and WebAssembly are not supported yet.


Get PySide6 via pip by running: pip install pyside6

  • Development Notes by date: the summary of the development progress.
  • Qt for Python Development Progress Notes The most current view of the progress can be found in Jira: Unresolved issues and All issues (including resolved). The second link is useful to monitor the progress of the backlog. The best way to achieve this is to sort the list by the "Updated" column. Larger backlog/feature items are filed as "User Stories" in Jira.
  • Missing PySide6 bindings: the list of the current missing bindings.
