Storing your configuration with StandardPaths

You have built your cross platform application, but in order to run your application on multiple platforms, you also need a standard way to access external resources, such as icons and user configuration data. Luckily, wxPython also has a cross platform way to access standard system paths. There are the platform-specific locations where applications store their user configuration data, which can be accessed through the StandardPaths singleton. In this recipe, we will take a look at how to set up and access application configuration data using StandardPaths.

How to do it…

Perform the following steps:

1. First, we will start by defining a class to help manage the configuration of an application:

   import os
   import json
   import wx
   
   class AppConfig(object):
       _instance = None
       def __init__(self):
           super(AppConfig, self).__init__()
   
           # create base dir if it doesnt exist
           if not os.path.exists(self.UserConfigDir):
               os.mkdir...
