system-pyside6

A Python package that exposes system-installed PySide6 packages into a virtual environment.

Usage

PySide6 publishes multiple packages to PyPI. Howevever, these packages include a full copy of Qt. As a result, a Python app that uses a virtual environment and specifies PySide6 as a dependency will not use the system version of Qt - and as a result, will not adopt the system theme. This leads to an app that doesn't look native, as it doesn't conform to the system look and feel.

This package provides a customization of the Python import system that allows system-installed Python packages to be used in a virtual environment.

NOTE: This is not an official Qt package!! The BeeWare project has provided this package to provide a way to write Python applications that use a virtual environment (or other forms of environment isolation) without the need to duplicate Qt libraries in the virtual environment.

To use system-pyside6, install the system packages for PySide6:

• Ubuntu / Debian - sudo apt-get install python3-pyside6.qtwidgets (and other modules you may need, such as python3-pyside6.qtcore; Only available from Ubuntu 24.10+ / Debian 13+)

• Fedora - sudo dnf install python3-pyside6, then sudo dnf upgrade --refresh

• Arch/ Manjaro - sudo pacman -Syu pyside6

• OpenSUSE Tumbleweed - sudo zypper install python3-pyside6

Then, create a virtual environment, and install system-pyside6 into that environment. You should then be able to write a Python app using PySide6 without adding PySide6 as a dependency of your app.
