jME 3.10.0-beta1

Many of my apps use GLFW to determine the available resolutions for full-screen display. I’m sure SDL3 has equivalent functionality;

This is what I’ve done so far:

    public List<VideoMode> getAvailableVideoModes() {
        initVideo();

        final List<VideoMode> videoModes = new ArrayList<>();
        final PointerBuffer displayModes = SDLVideo.SDL_GetFullscreenDisplayModes(display);

        for (int i = 0; i < displayModes.capacity(); i++) {
            final SDL_DisplayMode displayMode = SDL_DisplayMode.create(displayModes.get());
            final VideoMode videoMode = new VideoMode(displayMode.w(), displayMode.h(), displayMode.refresh_rate());
            videoModes.add(videoMode);
        }

        SDL_free_func.free(displayModes.address());

        return videoModes;
    }

    private void initVideo() {
        if ((SDLInit.SDL_WasInit(SDLInit.SDL_INIT_VIDEO) & SDLInit.SDL_INIT_VIDEO) == 0 && !SDLInit.SDL_Init(SDLInit.SDL_INIT_VIDEO)) {
            String message = SDLError.SDL_GetError();
            logger.log(Level.SEVERE, "CRITICAL ERROR: Failed to initialize SDL3 Video Subsystem!\n * {0}", message);
            throw new RuntimeException(message);
        }
    }

VideoMode is a record I created that holds only width, height and frequency, but SDL_DisplayMode has other data.

public record VideoMode(int width, int height, float refreshRate) {
}
