I first got the seg fault calling activate() on the input fields directly within the callback for the button., i only added the reset function to try and get around the issue or simply see if any difference. will this seg fault be heirarchy related also do you think ? I think a scope issue certainly but i can't understand why it compiled in that case. (using GCC with all warnings.) the includes are #include <FL/Fl.H> #include <FL/Fl_Window.H> #include <FL/Fl_Input.H> #include <FL/Fl_Int_Input.H> #include <FL/Fl_Button.H> #include<stdio.h> #include<stdlib.h> _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
