[STR New] Link: http://www.fltk.org/str.php?L1839 Version: 2.0-feature This is easy to do with the existing functionality. Make your callback something like this: void angle_cb(Widget *v, void *ob) { Dial *sd; sd = (Dial*)v; float val; float angle; val = (float) sd->value(); // Limit values, this makes the dial to rotate without limits if(val>0.75) sd->value(val-0.5); if(val<0.25) sd->value(val+0.5); // Get the range back angle = 720 * val; if (angle >= 360.0) angle-=360.0; // Do something with angle } When you create the dial you do it like this: test_dir = new LineDial(505,130,200,200,"Test dial angles"); test_dir->angles(-180,540); test_dir->value(0.5); test_dir->callback(angle_cb,this); Regards Thor Henning Amdahl Link: http://www.fltk.org/str.php?L1839 Version: 2.0-feature _______________________________________________ fltk-dev mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk-dev
