No auto-layout, identical coordinate systems. I found the solution, which is entirely my fault of course, thanks to your comment "It sounds like your NSView actually has white space at the top." For the benefit of future readers of this thread, here is the solution.
I assumed the underlying (scrolled) NSView must be correct because it always was correct when shown without the NSScrollView. (The NSScrollView was added only if the window layout would not fit on screen). But, the window was created from coordinates that are top down (origin top left). This has been managed before using any Cocoa code by something like this: cocoa_y = window_interior_height - design_y but of course, the window_interior_height is no longer interesting. I was subtracting from too small a number, and needed to be subtracting from the size assigned to the scrolled area. So I really, really did have a scrolled area with lots of white space at the top. Thank you for sending me straight to the solution! _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
