Try replacing the printf with fl_message. That will pop up a dialog box. The syntax is the same, so all you do is replace the text "printf" with "fl_message". You will also need to include FL/fl_ask.H (that is, if you are using FLTK 1.1.x I don't use Windows, but with KDevelop (Linux IDE), the stdout is buffered. The only way to be guaranteed that the printf's will appear is to use fprintf(stderr, ...) or launch the app in a console. In your example though, a fl_message should be appropriate as well. -- Alvin _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
