Examples
========================================================================================

There are example programs available for you to play with / understand how the different
pieces fit together.  The C++ examples are in ``nanogui/src/``, and the equivalent
Python examples are in ``nanogui/python``.

.. _nanogui_example_1:

Example 1

The first example program is rather long, but not altogether complicated.  It
is effectively an enumeration of how one would go about adding various different kinds
of Widgets to the window being displayed.

- `Example 1 in C++ <https://github.com/wjakob/nanogui/blob/master/src/example1.cpp>`_
- `Example 1 in Python <https://github.com/wjakob/nanogui/blob/master/python/example1.py>`_

.. _nanogui_example_2:

Example 2

The second program demonstrates how simple label/editor widget-type layouts can
be written in a very concise manner.

- `Example 2 in C++ <https://github.com/wjakob/nanogui/blob/master/src/example2.cpp>`_
- `Example 2 in Python <https://github.com/wjakob/nanogui/blob/master/python/example2.py>`_

.. _nanogui_example_3:

Example 3
----------------------------------------------------------------------------------------

The third example program demonstrates how to manage OpenGL / GLFW on your own for the
C++ side, and how to detach the NanoGUI ``mainloop()`` on the Python side.

- `Example 3 in C++ <https://github.com/wjakob/nanogui/blob/master/src/example3.cpp>`_
- `Example 3 in Python <https://github.com/wjakob/nanogui/blob/master/python/example3.py>`_

.. _nanogui_example_repository:

Example Repository
----------------------------------------------------------------------------------------

Darren Mothersele has put together a compact and informative example repository that
demonstrates how easy it is to include NanoGUI into your project.  You download / browse
the source on `GitHub <https://github.com/darrenmothersele/nanogui-test.git>`_.
