Good idea to ask ;-) It's much easier than you thought. Fl_Secret_Input is derived from Fl_Input_, and you can set the type() to change its behavior. Here are the type definitions from the FLTK 1.3 docs (FLTK 1.1 is identical): #define FL_NORMAL_INPUT 0 #define FL_FLOAT_INPUT 1 #define FL_INT_INPUT 2 #define FL_MULTILINE_INPUT 4 #define FL_SECRET_INPUT 5 #define FL_INPUT_TYPE 7 #define FL_INPUT_READONLY 8 #define FL_NORMAL_OUTPUT (FL_NORMAL_INPUT | FL_INPUT_READONLY) #define FL_MULTILINE_OUTPUT (FL_MULTILINE_INPUT | FL_INPUT_READONLY) #define FL_INPUT_WRAP 16 #define FL_MULTILINE_INPUT_WRAP (FL_MULTILINE_INPUT | FL_INPUT_WRAP) #define FL_MULTILINE_OUTPUT_WRAP (FL_MULTILINE_INPUT | FL_INPUT_READONLY | FL_INPUT_WRAP) Basically you must set one of the type values in [0-5] and or this with FL_INPUT_READONLY if you need it. Just change the type() accordingly and call redraw(). You need only one widget.
