Hey,

I have a simple OpenGL drawing. When the user changes the window's size, I want the drawing to maintain it's aspect ration. I accomplished that by setting the glViewport to the maximum rectangle with the appropriate aspect ration whenever the reshape method is called.

My problem is that I want to draw a square that will always remain in the top right corner of the window, no matter what the size or shape of the window is. Right now, that square moves around the screen whenever the window is reshaped.

Can anyone please explain how to do this?

Thank you,
