        [w setStyleMask:(oldStyleMask|maskIn) & ~maskOut];

        // Set the window to full screen
        [w setFrame:[[w screen] visibleFrame] display:YES];
        
        // Make it at the front
        oldLevel  = [w level];
        [w setLevel:NSFloatingWindowLevel];
    }
    else
    {
        // Restore everything back to where it should be
        [w setLevel:oldLevel];
        [w setStyleMask:oldStyleMask];
        [w setFrame:nonFullScreenRect display:YES animate:NO];
        [NSMenu setMenuBarVisible:YES];
    }

    // Toggle the fullscreen status
    fullScreen = !fullScreen;
}

Really this should be in the window rather than the view

But there you go :)
