Hi there,
sorry for the huge post.

This code works perfectly, but, if I change the block

       gl.glBegin( GL.GL_TRIANGLES );
           gl.glVertex3f( 0.0f, 0.0f, 0.0f );
           gl.glVertex3f( 1.0f, 0.0f, 0.0f );
           gl.glVertex3f( 1.0f, 1.0f, 0.0f );
       gl.glEnd();

      gl.glBegin( gl.GL_QUADS );
         gl.glVertex2i(100, 150);
         gl.glVertex2i(100, 100);
         gl.glColor3f(0.0f, 0.0f, 1.0f);
         gl.glVertex2i(150, 100);
         gl.glVertex2i(150, 150);        
      gl.glEnd();

it just doen´t do nothing ... (nothing but a black screen)
The only thing that changed was the fact that it is no longer a GL_TRIANGLE and it is glVertex2i instead of glVertex3f.
I am a newbie on OpenGL, so I would think it is wierd if I missed something on the rest of the code ...

Thanks for your attention and time,

Have a nice day,
