Using GLFW 3 as a Window and Context Creator

[Vlad Abadzhiev-Jahn]

I'm trying to migrate to OpenGL.Net using GLFW3 with these bindings (https://github.com/realvictorprm/GLFW3.NET) and I'm getting a black window with no errors.

I'm having trouble understanding how to interface the contexts between the two libraries, and have so far written this:

        Glfw.Init();
        Glfw.WindowHint((int) State.ContextVersionMajor, 3);
        Glfw.WindowHint((int) State.ContextVersionMinor, 3);
        Glfw.WindowHint((int) State.OpenglForwardCompat, 1);
        Glfw.WindowHint((int) State.OpenglProfile, (int) State.OpenglCoreProfile);
        Glfw.WindowHint((int) State.OpenglDebugContext, 1);

        Gl.Initialize();

        GLFWwindow win = Glfw.CreateWindow(settings.WindowWidth, settings.WindowHeight, settings.WindowTitle,
        null, null);
        Glfw.MakeContextCurrent(win);

        Gl.BindAPI();

This works for me:

    static void Main(string[] args)
    {
        GLFWwindow mainWindow = Glfw.CreateWindow(800, 600, "Hello World", null, null);
        
        if (mainWindow == null)
        {
            Glfw.Terminate();
            return;
        }

        Gl.Initialize();
        Glfw.MakeContextCurrent(mainWindow);
        
        System.Console.WriteLine(Gl.CurrentVersion);
        System.Console.WriteLine(Gl.CurrentShadingVersion);

        while (Glfw.WindowShouldClose(mainWindow) <= 0)
        {
            Glfw.PollEvents();
            Render();
            Glfw.SwapBuffers(mainWindow);
        }

        Glfw.Terminate();
    }

    public static void Render()
    {
        Gl.Viewport(0, 0, 800, 600);
        Gl.Clear(ClearBufferMask.ColorBufferBit);

        Gl.MatrixMode(MatrixMode.Projection);
        Gl.LoadIdentity();
        Gl.Ortho(0.0, 1.0f, 0.0, 1.0, 0.0, 1.0);
        Gl.MatrixMode(MatrixMode.Modelview);
        Gl.LoadIdentity();

        Gl.Begin(PrimitiveType.Triangles);
        Gl.Color3(1.0f, 0.0f, 0.0f); Gl.Vertex2(0.0f, 0.0f);
        Gl.Color3(0.0f, 1.0f, 0.0f); Gl.Vertex2(0.5f, 1.0f);
        Gl.Color3(0.0f, 0.0f, 1.0f); Gl.Vertex2(1.0f, 0.0f);
        Gl.End();
    }
