Sphinx Qt documentation

This is plugin to add cross link to qt documentation for python code created with PyQt5 or PySide2.

Currently it support qtpy, Qt.py wrappers and PyQt5 and PySide2.

This extension provides one configuration option:

qt_documentation with possible values:

• PyQt5 - linking to PyQt documentation on https://www.riverbankcomputing.com/static/Docs/PyQt5/ (incomplete)
• Qt5 - linking to Qt5 documentation on "https://doc.qt.io/qt-5/" (default)
• PySide2 - linking to PySide2 documentation on "https://doc.qt.io/qtforpython/PySide2/"

For default this extension use inv file from PyQt5 to resolve objects. to overwrite this behaviour set another url for intersphinx_mapping[PyQt5] ex.:

intersphinx_mapping = {...
                       "PyQt5": (custom_url, None),
                       ...}
