Re: Resizing window

My Quartz composition is in an OpenGLContext in an NSWindow.

If I change the size of the window, using setFrame, the composition does not
scale accordingly, but remains at the original resolution. i.e. if the width
and height of the window are halved, one only sees the top left quarter of
the composition area.

I have found a workaround :-

            [_openGLContext clearDrawable];
            [_window setFrame:rect display:NO];
            [_openGLContext setView: [_window contentView]];


However this seems like a using a hammer to crack a nut. Is there any way to
force the QC composition to rescale with the window ?

There's a bug in the QCRenderer where it does pick up automatically OpenGL viewport changes and this affect the rendering of some compositions. The only workaround is to destroy / recreate the renderer when rendering dimensions change.

However, it does not seem that this is what you're encountering: can you send me a test case?
