Sure, no problem. Since it’s a bit long, I attached it as a separate ObjC source file. A few notes: * It’s rather old code (not made by me) that I haven’t looked into for years until this problem appeared. * I rearranged it a bit for easier reading, so there may be some copy/paste/typo errors, but you should get the overall idea what it does. * All drawing related code is contained within unique methods, no overriding. * I was “lying”, there is a small NSButton category (defined within the same file), but it just checks if a button is of a checkbox type. Thanks for looking into this, as I really hit a dead end with it.
