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 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.

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 GPL, LGPL and commercial license.

What does Qt for Python look like?

import sys
from PySide2.QtWidgets import QApplication, QLabel
                                                     
if __name__ == "__main__":
    app = QApplication(sys.argv)
    label = QLabel("Hello World")
    label.show()
    sys.exit(app.exec_())

More examples can be found in the project's repository inside the examples directory.

Development Status

Weekly development progress

The summary of the development progress can be found in Development Notes by date

Pyside Development Progress Notes

The most current view of the progress can be found in Jira:

1. Unresolved issues
2. 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 PySide2 bindings

The list of the current missing bindings can be found in Missing PySide2 bindings

Outstanding tasks for release

1. General Doc changes required for release
   1. Getting started
   2. Pyinstaller usage
   3. Class documentation polish
   4. snapshot generation on http://doc-snapshot.qt-project.org/

Frequently Asked Questions

• Q: PySide? Qt for Python? what is the name?
  • 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 changed to PySide2 to imply that it 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 not to use it.
• Q: My project is using PySide, how hard would it be to adapt it to PySide2?
  • A: The changes are the same as between Qt4 and Qt5, and for PySide users it mostly means adapting the import statements 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 to Qt 5 with their current functionality and gradually develop new things, leveraging all the great items Qt 5 makes possible.

• Q: Does PySide2 support Android and iOS development / deployment?
  • At the moment there is no support for mobile platforms. It will be looked into in the future.
• Q: Does PySide2 have support for embedded Linux (Raspberry Pi, i.MX6 etc)?
  • Not at the moment. It will be looked into in the future.
• Q: Why shiboken2_generator is not installed automatically?
  • It's not necessary to install it to use PySide2. The package is the result of the wheel splitting process. To use the generator it's recommended to build it from scratch to have the proper Qt-linking.
