All is still not well. When the value is edited via the keyboard the callback does not get called. The line in Fl_Sinner.H that reads input_.when(FL_WHEN_ENTER_KEY | FL_WHEN_RELEASE); needs to be changed to read input_.when(FL_WHEN_ENTER_KEY | FL_WHEN_RELEASE | FL_WHEN_CHANGED); Now the callback gets executed after a keyboard edit (as it should). _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
