Maybe it works for non-athena widget sets, too, haven't checked. I don't think you can easily get information about sub/superclass that way, though, just the class that the different widgets declare themselves to be. Lots and lots of widget leaks there, as far as I can tell; haven't had a chance to look carefully, but it doesn't take long to get a couple copies of scrollbars and multiple copies of the tabs widget with only one frame up.
