Having a large project as the Qt Framework available from one simple installation line:
pip install pyside6
is really beneficial, but it might be confusing to newcomers.
Besides your IDE, you don’t need to install anything else to develop your Qt application, because the same command installs many tools that will help you design UIs, use QML types, generate files automatically, translate applications, etc.
Starting from 6.3.0, the
pyside6 package (wheel) is almost empty,
and only includes references to other packages that are required
to properly use all the modules.
This packages are:
pyside6-essentials, essential Qt modules,
pyside6-addons, additional Qt modules,
shiboken6, a utility Python module.
You can verify this by running
pip list to check the installed
packages in your Python (virtual) environment:
(env) % pip list Package Version ------------------ ------- pip 22.0.4 PySide6 6.3.0 PySide6-Addons 6.3.0 PySide6-Essentials 6.3.0 setuptools 58.1.0 shiboken6 6.3.0
pyside6-addons contain Qt binaries
.dylib) that are used by the Python wrappers
that enable you to use the Qt modules from Python.
For example, in the
QtCore module, you will find
site-packages directory of your (virtual) environment.
The first is the importable module which depends on the second file
which is the original QtCore library.
shiboken6-generator is not a dependency,
and it’s not available on PyPi. The reason, is that it depends on
libclang, which is a large library that we don’t package, and
requires a special configuration for you to use. Check the Shiboken
Documentation for more details.
Following the same idea from the modules, we also include in the packages
(wheels) Qt tools that are important for any Qt application development
All the tools must be used from the PySide wrappers, and not directly.
For example, if exploring the
site-packages/ directory on your installation
uic.exe (on Windows), you should not click on that, and use
The reason for this is the proper setup of PATHs, plugins, and more,
to properly work with the installed Python package.
Here you can find all the tools we include in Qt for Python starting from 6.3.0, grouped by different topics:
pyside6-project, to build Qt Designer forms (
.uifiles), resource files (
.qrc) and QML type files (
.qmltype) from a
pyside6-designer, drag-and-drop tool for designing Widget UIs (generates
pyside6-uic, to generate Python code from
pyside6-rcc, to generate serialized data from
.qrcresources files. Keep in mind these files can be used in other non-widget projects.
pyside6-qmllint, that verifies the syntactic validity of QML files.
pyside6-qmltyperegistrar, to read metatypes files and generate files that contain the necessary code to register all the types marked with relevant macros.
pyside6-linguist, for translating text in applications.
pyside6-lrelease, to create run-time translation files for the application.
pyside6-lupdate, to synchronize source code and translations.
pyside6-assistant, for viewing online documentation in Qt Help file format. Read more about the formats on the QtHelp Framework page.
pyside6-genpyi, to generate Python stubs (
.pyifiles) for Qt modules.
pyside6-metaobjectdump, a tool to print out the metatype information in JSON to be used as input for
