ZenGUI is a cross platform application framework that I wrote for Macintosh and Windoze 3.1. It is simple, yet functional (mostly) and was designed after what I thought that truely portable objects should be designed like. It is written in C++ and even has stupid 8.3 filenames. (There are _some_ problems with the Windoze version as I don't have a windoze box)
ZenGUI started out of a simple enough idea: I hated a book by (TODO). I thought that despite the fact that he was published and I was but a second year college student, that my OO design skills were far superior to his. They were. That is by far the worst OO book I have ever read and I am really sorry that I lost it. I will write someday and I could use that book as a guideline of how not to write.
