Getting Started on Windows
==========================
The Qt library has to be built with the same version of MSVC as Python and PySide2, this can be
selected when using the online installer.
Requirements
------------
* Qt package from `here`_ or a custom build of Qt (preferably Qt 5.12
or greater)
* A Python interpreter (version Python 3.5+). Preferably get it
from the `official website`_.
* `MSVC2017`_ (or MSVC2019) for Python 3 on Windows,
* `CMake`_ version 3.1 or greater
* `Git`_ version 2 or greater
* `libclang`_ prebuilt version from the
``Qt Downloads`` page is recommended.
* `OpenSSL`_ (optional for SSL support, Qt must have been
configured using the same SSL library).
* ``virtualenv`` is strongly recommended, but optional.
* ``sphinx`` package for the documentation (optional).
.. note:: Python 2.7 interpreter is not supported.
The official Python 2.7 binary package offerred on the
`official website`_ is built using MSVC 2007, while
the Qt libraries are built using MSVC 2015/2017.
If you intend to use Python 2.7, build the interpreter yourself
with MSVC 2015 or later, and build Qt for Python with it.

Building from source on Windows 10
----------------------------------
Creating a virtual environment
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
``virtualenv`` allows you to create a local, user-writeable copy of a python environment into
which arbitrary modules can be installed and which can be removed after use::
virtualenv testenv
call testenv\scripts\activate
pip install sphinx # optional: documentation
pip install numpy PyOpenGL # optional: for examples
will create and use a new virtual environment, which is indicated by the command prompt changing.
Setting up CLANG
~~~~~~~~~~~~~~~~
If you don't have libclang already in your system, you can download from the Qt servers,
e.g. ``libclang-release_60-windows-vs2015_64-clazy.7z``.
Extract the files, and leave it on any desired path, e.g ``c:\``, and then set these two required
environment variables::
set LLVM_INSTALL_DIR=c:\libclang
set PATH=C:\libclang\bin;%PATH%
Getting PySide2
~~~~~~~~~~~~~~~
Cloning the official repository can be done by::
git clone --recursive https://code.qt.io/pyside/pyside-setup
Checking out the version that we want to build, e.g. 5.14::
cd pyside-setup && git checkout 5.14
.. note:: Keep in mind you need to use the same version as your Qt installation
Building PySide2
~~~~~~~~~~~~~~~~
Check your Qt installation path, to specifically use that version of qmake to build PySide2.
e.g. ``E:\Qt\5.12.0\msvc2015_64\bin\qmake.exe``.
Build can take a few minutes, so it is recommended to use more than one CPU core::
python setup.py build --qmake=c:\path\to\qmake.exe --openssl=c:\path\to\openssl\bin --build-tests --ignore-git --parallel=8
Installing PySide2
~~~~~~~~~~~~~~~~~~
To install on the current directory, just run::
python setup.py install --qmake=c:\path\to\qmake.exe --openssl=c:\path\to\openssl\bin --build-tests --ignore-git --parallel=8
Test installation
~~~~~~~~~~~~~~~~~
You can execute one of the examples to verify the process is properly working.
Remember to properly set the environment variables for Qt and PySide2::
python examples/widgets/widgets/tetrix.py
