That indeed helps. I didn't know that there is relative positioning. Also, thanks for the MVC hint. It looks like I can use this concept very well. I have lots of preset/master setup data (Model), I have an UI to View the data, and i need a Controller to load and change the data as well as to convert between raw data and widget values. So, three classes with some set/get/data-converter methods. Allright, I think i can manage that after some C++ tutorials. :) Thank you again guys, Jan _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
