I wish to make a NSOpenGLView transparent as the title says.
The app has a NSWindow and the contentview is a NSOpenGLView. That's all.
On the Mac I use (in combination with making the window transparent)
long value = 0;
[openGLContext setValues:&value forParameter: NSOpenGLCPSurfaceOpacity];
to achieve this but this doesn't seem to be implemented in GNUstep.
Anyone have any idea if it is possible at the current state to accomplish this in any other way?
