Is the ciUI library still supported, I mean any other forks other than that of RezaAli?
I think there’s a few forks, but if you’re looking for UI components I would use IMGUI. It comes standard with Cinder now and it’s a popular cross-platform solution with lots of tutorials and a solid community.
Back when I used ciUI - admittedly almost 9 years ago now - I recall the library not being fully fleshed out. I.e. widgets did not have any sort of unique id as far as I recall, which is a feature you’ll sorely miss. It’s not super hard to add as such, but my advice would also be to look for alternatives unless ciUI has progressed a fair bit since then.
Looks like imgui is a better option as Mr.Nathan suggested.
