I would like to know how I can force a bog standard NSOpenGLView to refresh its content. Is it as simple as saying : [theView setNeedsDisplay:YES]

Cos when I do this, my draw method does get called (i.e. drawRect:), but the image on the view itself does not change. When I resize the view, the image is then updated immediately. Anyone else seen this kinda of thing before?

Is your NSOpenGLView double-buffered? If so, are you calling the - flushBuffer method at appropriate times?

Kind regards,

Alastair.
