I like the idea of being able to change or disable the symbol prefix
char,
I don't think it works as a config option. (For instance, this would
break
in a dll environment, where the user's system would have stock fltk
dlls)
I'd offer this alternative suggestion: to retain back compatibility
with old apps, but allow new apps to still use/change/disable symbols,
I could see creating two new api calls; Fl::symbol_char() and
Fl::symbol_str():
Fl::symbol_char(0); // disables symbols throughout
FLTK app
Fl::symbol_char('@'); // sets the symbol char
(default)
Fl::symbol_char(0x0f); // sets symbol char to 0x0f
char c = Fl::symbol_char(); // gets the current symbol char
std::string rightarrow = Fl::symbol_str("->"); // get an FLTK symbol string
This way if the symbol char is default (@), Fl::symbol_str("->")
would return "@->", but if the symbol char were 0, Fl::symbol_str("->")
would return "".
