-Chapter 2: ``bookdelegate.cpp`` to ``bookdelegate.py``
-*******************************************************
-
-Now that your database is in place, port the C++ code for the
-``BookDelegate`` class. This class offers a delegate to present
-and edit the data in a ``QTableView``. It inherits
-``QSqlRelationalDelegate`` interface, which offers features
-specific for handling relational databases, such as a combobox
-editor for foreign key fields. To begin with, create
-``bookdelegate.py`` and add the following imports to it:
-
-.. literalinclude:: bookdelegate.py
-   :language: python
-   :linenos:
-   :lines: 40-47
-
-After the necessary ``import`` statements, port the
-constructor code for the ``BookDelegate`` class. Both
-the C++ and Python versions of this code initialize a
-``QSqlRelationalDelegate`` and ``QPixmap`` instance.
-Here is how they look:
-
-C++ version
--------------
-
-.. literalinclude:: bookdelegate.cpp
-   :language: c++
-   :linenos:
-   :lines: 54-59
-
-Python version
----------------
-
-.. literalinclude:: bookdelegate.py
-   :language: python
-   :linenos:
-   :lines: 47-54
-
-.. note:: The Python version loads the ``QPixmap`` using
-   the absolute path of ``star.png`` in the local
-   filesystem.
-
-As the default functionality offered by the
-``QSqlRelationalDelegate`` is not enough to present
-the books data, you must reimplement a few functions.
-For example, painting stars to represent the rating for
-each book in the table. Here is how the reimplemented
-code looks like:
-
-C++ version
-------------
-
-.. literalinclude:: bookdelegate.cpp
-   :language: c++
-   :linenos:
-   :lines: 59-
-
-Python version
----------------
-
-.. literalinclude:: bookdelegate.py
-   :language: python
-   :linenos:
-   :lines: 55-
-
-Now that the delegate is in place, run the following
-``main.py`` to see how the data is presented:
-
-.. literalinclude:: main.py
-   :language: python
-   :linenos:
-   :lines: 40-
-
-Here is how the application will look when you run it:
-
-.. image:: images/chapter2_books.png
-   :alt: Books table data
-
-The only difference you'll notice now in comparison to
-:doc:`chapter 1 <../chapter1/chapter1>` is that the
-``rating`` column looks different.
-
-Try improving the table even further by adding these
-features:
-
-* Title for each column
-* SQL relation for the ``author_id`` and ``genre_id`` columns
-* Set a title to the window
-
-With these features, this is how your table will look like:
-
-.. image:: images/chapter2_books_with_relation.png
-   :alt: Books table with SQL relation
