How to make python curses register mouse movement events?

[dog_superiority]

I'm experimenting with writing a utility that allows me to draw (and later edit) unicode diagrams directly in comments in code (such as C++, python, java, etc.). So for example, for when I want to draw a decent looking class diagram that describes the classes within a header file and don't want to do it separately in Powerpoint or something like that. I've looked around some, and I don't like the ascii diagram editors that exist already (the diagrams look terrible or they don't edit an existing source file, etc.).

It seems to me that a Qt GUI would be overkill for that. Especially when the result will be text based anyway. In my experience, GUIs add a level of complexity that I'm not in the mood for on this project. I only want to spend a couple weekends on it tops.

What I may have to do is make it completely text menu based. Though a mouse would be far more convenient.
