Nothing per se, as fltk does not support serialization and persistance. Overall, serialization in C/C++ is a pain in the neck, as the language does not make it easy, so expect to write some special code for each class you use. The best mixed ascii/binary format for serialization is called YAML (which is a simplified and better version of JSON). JSON is now used everywhere as part of AJAX and Web2.0 in things such as Google maps and the like. Albeit there's currently no C++ YAML library, you can use a C++ JSON library like Jaula and get almost 90% there. The s11n library also now allows serializing to a JSON grammar, among other 5 other formats. A not so good but popular alternative is called XML, which is a full featured language, with a lot of quirks but became popular since it was one of the earliest formats to appear. There are several C++ libraries for XML: GNU's CPP framework, Eternity, etc. Best library out there for C++ serialization (in features and documentation) is probably boost::serialization. It allows versioning on a per class basis, which is very useful and not present on other alternatives. By default it uses its own custom binary format, but has support for XML. -- Gonzalo Garramuño [EMAIL PROTECTED] AMD4400 - ASUS48N-E GeForce7300GT Kubuntu Edgy _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
