That is correct. You see the erroro message because FLTK finds an argument in the list that is not supported by FLTK's default arguments interpreter. So the cheapest way out is the one solution above. You should still interpret the arguments elsewhere, and your user loses the ability to change the color scheme or theme. The first alternative is to make a copy of argv (you know how long it is using argc) and then removing entries that your application understands (filename frm a dnd operation on the icon, etc.). You then call show(myArgc, myArgv)... . The second alternative uses Fl::arg(int, char **, int &, Fl_Args_Handler *) which calls your handler before handing an argument to FLTK. <http://www.fltk.org/doc-1.3/classFl.html#1576b8c9ca3e900daaa5c36ca0e7ae48> _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
