Feature requests / Re: Way to use Window without GL (ALREADY DONE, woop), and maybe user data ptr in it
« on: February 14, 2019, 09:48:46 pm »
With https://github.com/binary1248/SFML/commit/ef593102ba730c300895109125860e5ab59d3c63 you can do what you want:
The question is... should I open a pull request in the main repository for this...
