PySide6

PySide6

Introduction

Important: for Qt5 compatibility, check PySide2

PySide6 is the official Python module from the Qt for Python project, which provides access to the complete Qt 6.0+ framework.

The Qt for Python project is developed in the open, with all facilities you'd expect from any modern OSS project such as all code in a git repository and an open design process. We welcome any contribution conforming to the Qt Contribution Agreement.

Installation

Since the release of the Technical Preview it is possible to install via pip, both from Qt's servers and PyPi:

pip install PySide6

Please note: this wheel is an alias to other two wheels PySide6_Essentials and PySide6_Addons, which contains a predefined list of Qt Modules.

Dependencies

PySide6 versions following 6.0 use a C++ parser based on Clang. The Clang library (C-bindings), version 13.0 or higher is required for building. Prebuilt versions of it can be downloaded from download.qt.io.

After unpacking the archive, set the environment variable LLVM_INSTALL_DIR to point to the folder containing the include and lib directories of Clang:

7z x .../libclang-release_100-linux-Rhel7.2-gcc5.3-x86_64-clazy.7z
export LLVM_INSTALL_DIR=$PWD/libclang

On Windows:

7z x .../libclang-release_100-windows-vs2015_64-clazy.7z
SET LLVM_INSTALL_DIR=%CD%\libclang

Building from source

For building PySide6 from scratch, please read about getting started. This process will include getting the code:

git clone https://code.qt.io/pyside/pyside-setup
cd pyside-setup
git checkout 6.x # if a specific version is needed

then install the dependencies, and following the instructions per platform. A common build command will look like:

python setup.py install --qtpaths=/path/to/bin/qtpaths6 --parallel=8 --build-tests

You can obtain more information about the options to build PySide and Shiboken in our wiki.

Documentation and Bugs

You can find more information about the PySide6 module API in the official Qt for Python documentation.

If you come across any issue, please file a bug report at our JIRA tracker following our guidelines.

Licensing

PySide6 is available under both Open Source (LGPLv3/GPLv3) and commercial license. Using PyPi is the recommended installation source, because the content of the wheels is valid for both cases. For more information, refer to the Qt Licensing page.
