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

  • 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.
