4 years ago Is there still no way to track mouse events? I tried manually enabling mouse tracking with escape sequences and parsing the sequences that inkey() returns. It works fine until I click on a spot where the x or y coordinate is bigger than 127, and that makes blessed throw an exception, because the getch() method tries to decode the bytes representing the coordinates as unicode, and fails.
I really want to be able to track mouse events from my application, so if someone could tell me a way to do it, I would be very grateful.

this was already done once before in a rejected blessings patch last year,
https://asciinema.org/a/2871 <- scroll wheel https://asciinema.org/a/2866 <- click detection

Not so sure about the given solution, I need to be persuaded about the context manager names and possible keyword argument/values.
Furthermore, the "Keystroke" class type returned by Terminal.inkey() can now return MouseEvent as well -- they now need to derive from the same base class, providing the same .code and .is_sequence() methods. I think I would further like attribute "kind" of values "MouseEvent" or "keystroke".
Mouse input provides (x,y) attributes, but even bounding box attributes etc., a class needs to be made to support all such decoding, example of decoding and game is done here ("drawing boxes" demo)
