I was going to do variables but wanted to do at compile time to use string concatenation to keep things as close to the same as possible and not have to deal with building and managing strings since without the new always copy label option enabled, or using copy_label, the strings returned have to be persist. A varaible method may be good for something in 3.0? _______________________________________________ fltk-dev mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk-dev
