There would be two separate slider "knobs" available. One with a direction, and one with a simple dimple (the round one in jimmac's mockup). We could either say: "if all the marks are below, we'll draw a pointy slider, otherwise the round one". But that would sort of break the clean divide between themess and GTK+ itself (some themes might want to have pointy sliders when things are above too, etc.). So we'd need a way to export the marks positions to the engine, and adding style classes doesn't scale (we'd need to add 4 separate ones for this to work). _______________________________________________ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list
