Union-pointers sound like a neat trick. Can't you generate headers with these union-pointer declarations automatically, using gobject introspection? I'm also not sure what are the ABI implications. Are unions compile-time only? I guess you'd only change a pointer-union if the class hierarchy of its corresponding widget class changes, which sounds like a good excuse to recompile anyway... -- O< ascii ribbon - stop html email! - www.asciiribbon.org
