[[File:Py-128.png|thumb|left|Qt for Python official logo.]] The '''[https://www.qt.io/qt-for-python Qt for Python]''' project aims to provide a complete port of the [[PySide]] module to Qt. 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] ).

* Q: PySide? Qt for Python? what is the name?
*[[Qt_for_Python_Development_Notes|Development Notes by date]]: the summary of the development progress.
** 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?
*[[Qt_for_Python_Missing_Bindings|Missing PySide6 bindings]]: the list of the current missing bindings.
** 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 [https://doc.qt.io/qt-5/qt5-intro.html 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: There are three wheels ('''pyside2''', '''shiboken2''', and '''shiboken2_generator''') what is the difference between them?
** Before the official release, everything was in one big wheel, but it made sense to split the projects in three different wheels:
*** '''pyside2''': contains all the PySide2 module for all the Qt libraries. Also depends on the ''shiboken2'' module.
*** '''shiboken2''': contains the shiboken2 module with helper functions for PySide2.
*** '''shiboken2_generator''': contains the generator binary that can work with a C++ project and a typesystem to generate Python bindings. Take into account that if you want to generate bindings for a Qt/C++ project, the linking to the Qt shared libraries will be missing, and you will need to do this by hand. We recommend to build PySide2 from scratch to have everything properly linked.
* 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 [https://bugreports.qt.io/browse/PYSIDE-749 wheel splitting process]. To use the generator it's recommended to build it from scratch to have the proper Qt-linking.

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

What does it look like?

Code Application 
import sys
from PySide6.QtCore import Qt
from PySide6.QtWidgets import QApplication, QLabel
                                                     
if __name__ == "__main__":
    app = QApplication(sys.argv)
    label = QLabel("Hello World", alignment=Qt.Alignment.AlignCenter)
    label.show()
    sys.exit(app.exec())
