View source for Adding a class to Qt for Python

[[Category:Qt for Python]]
[[Qt for Python Missing Bindings|Some C++ Qt classes]] are not yet exposed in Qt for Python.
This page describes how to add one, or even add a class of your own.

Overall the process should consist on:
*  Add the new class into the module's type system e.g.: <kbd>pyside-setup/sources/pyside2/PySide2/QtCore/typesystem_core_common.xml</kbd>
*  Add a couple of test cases: e.g.: <kbd>pyside-setup/sources/pyside2/tests/QtCore/</kbd> (don't forget to include the name of the scripts in the <kbd>cmake</kbd> file in the same directory)

If you are lucky, the new class will require no extra steps,
but probably it will, so for this we recommend that you look
at a similar class so you can get an idea of how to solve the
issues you find. These issues could include:

* Ownership transfer
* Casting argument to different types
* Explicitly declare <kbd>enum</kbd>s
* Adapt method signatures
* Include new signatures for a certain method
