I just discovered gpui it’s a UI library based on the GPU. It was created by the same team that make Zed (the code editor). And I found out that it very personalizable. So I am rewriting DMGTile in it . So far I have the basic grid and basic tools like the bucket, the pencil, eraser etc… The only problem is that I can’t track the right click drag. (I also got the native macOS toolbar)
