Function SDL_SetWindowIcon
pub unsafe extern "C" fn SDL_SetWindowIcon(
window: *mut SDL_Window,
icon: *mut SDL_Surface,
) -> bool
dep_sdl3
only.Expand description
Set the icon for a window.
If this function is passed a surface with alternate representations, the surface will be interpreted as the content to be used for 100% display scale, and the alternate representations will be used for high DPI situations. For example, if the original surface is 32x32, then on a 2x macOS display or 200% display scale on Windows, a 64x64 version of the image will be used, if available. If a matching version of the image isn’t available, the closest larger size image will be downscaled to the appropriate size and be used instead, if available. Otherwise, the closest smaller image will be upscaled and be used instead.
