Mypy stubs for the PyQt5 framework

This repository holds the stubs of the PyQt5 framework. It uses the stub files that are produced during compilation process of PyQt5. These stub files have been modified by the author to allow using them for type-checking via Mypy. This repository is far from complete and the author will appreciate any PRs or Issues that help making this stub-repository more reliable.

Installation

Simply install PyQt5-stubs with pip:

$ pip install PyQt5-stubs

Or clone the latest version from Github and install it via Python setuptools:

$ git clone https://github.com/stlehmann/PyQt5-stubs.git
$ python setup.py install

Supported Modules

The following modules are supported by PyQt5-stubs:

• QtCore
• QtWidgets
• QtGui
• QtDBus
• QtNetwork
• QtOpenGL
• QtPrintSupport
• QtSql
• QtTest
• QtXml
• sip

Building upstream stubs

The Dockerfile is used to build all of the stubs for the upstream PyQt5 modules. The Dockerfile consists of multiple build layers:

• core: PyQt5
• PyQt3D
• PyQtChart
• PyQtDataVisualization
• PyQtPurchasing
• PyQtWebEngine
• an output layer

Each module build layer deposits its stub files within /output/ in its filesystem. The output layer then collects the contents of each into its own /output/ dir for export to the host computer. Build args are provided to change the version of each module.

A convenience script, build_upstream.py, is provided. It builds the stubs and copies them to the host computer. Make sure you install docker-py to use it. It builds $PWD/Dockerfile (overridden with --dockerfile) and outputs the stubs to $PWD/PyQt5-stubs (overridden with --output-dir).

* There are a few missing modules: QtAxContainer, QtAndroidExtras, QtMacExtras, and QtWindowsExtras. The current project understanding is that they need to be built on the target platform, something a Linux-based docker image cannot do. The deprecated Enginio module is also missing.
