OpenTK Example

Hi there,

I followed the very first example provided in the OpenTK manual. The data builds successfully; however as it runs, the glControl1 still come out white.

Below is the code. Please help. I'm pretty sure that I'm missing a setup step. Thanks.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

using OpenTK.Graphics;
using OpenTK.Graphics.OpenGL;

namespace Trial003
{
public partial class Form1 : Form
{
bool loaded = false;

public Form1()
{
InitializeComponent();
}

private void glControl1_Load(object sender, EventArgs e)
{
loaded = true;
GL.ClearColor(Color.SkyBlue);
}

private void glControl1_Paint(object sender, PaintEventArgs e)
{
if (!loaded)
return;
GL.Clear(ClearBufferMask.ColorBufferBit | ClearBufferMask.DepthBufferBit);
glControl1.SwapBuffers();
}
}
}
