Writing a Notes desktop application

Let's do something interesting with the RPC API. What if users could manage their Odoo to-do tasks directly from their computer's desktop? Let's write a simple Python application to do just that, as shown in the following screenshot:

For clarity, we will split it into two files: one concerned to interact with the server backend, note_api.py, and another with the graphical user interface, note_gui.py.

Communication layer with Odoo

We will create a class to set up the connection and store its information. It should expose two methods: get() to retrieve task data and set() to create or update tasks.

Select a directory to host the application files and create the note_api.py file. We can start by adding the class constructor, as follows:

import xmlrpclib
class NoteAPI():
    def __init__(self, srv, db, user, pwd):
        common = xmlrpclib.ServerProxy(
            '%s/xmlrpc/2/common' % srv)
        self.api = xmlrpclib.ServerProxy(
            '%s/xmlrpc/2/object...
