Cleaning up my desktop, I looked at this odd little App, which is a sort of document organizer / outliner thing, except that it stores everything in one XML file. Like I said, odd, and the programmer (who is apparently Japanese) doesn’t say much to dispell the mystery.
Anyway, that app uses a nice-looking toolkit called FOX, And looking at it made me look up other GUI toolkits (there are lots). One of these is called V, and it’s creator (Dr. Bruce E. Wampler, a professor of Computer Science and serious software engineer) also has some interesting stuff on Object Oriented programming on his site, including a draft of a book.
