Coming to this party late, but I just remembered that Jason Bryan's FLU widgets have a double-slider widget. His pages at OSC.edu appear to be gone but the mirror here still seems to be working: http://src.gnu-darwin.org/ports/x11-toolkits/flu/work/FLU_2.14/ His FLU_Dual_Slider might be relevant, to see how what he did compares. He derived a pile of "new" fltk based widgets, so there may be clues in that work for a template for future derivations? _______________________________________________ fltk-dev mailing list fltk-dev@easysw.com http://lists.easysw.com/mailman/listinfo/fltk-dev
