OK, yeah, this looks pretty cool. There are a lot of situations where I want to store information, and a text file isn’t ideal, but running a full fledged database is overkill. I like the simplicity of the interface, especially the search function.
It sounds to me like you need to read through the PyGObject tutorials. If you’ve already read those, maybe try telling us exactly where you got stuck.
It would probably help if you were more specific about what part of the example you’re struggling to recreate. Maybe try sharing the relevant section of your code? Talk about what this particular component is supposed to do? Context is really important to these kinds of questions.
I guess if you’re measuring in execution time, negative would be an improvement.
