Sub_title: Not functioning...
 

So I am trying to cobble togeather my menu system and I figured - ncurses/curses can do everything I want (and more).

But I cannot get the function keys to respond.

Code:

#include <ncurses.h>

int main()
{   int ch;

   initscr();         /* Start curses mode       */
   raw();            /* Line buffering disabled   */
   keypad(stdscr, TRUE);      /* We get F1, F2 etc..      */
   noecho();         /* Don't echo() while we do getch */

       printw("Type any character to see it in bold\n");
   ch = getch();         /* If raw() hadn't been called
                * we have to press enter before it
                * gets to the program       */
   if(ch == KEY_F(1))      /* Without keypad enabled this will */
      printw("F1 Key pressed");/*  not get to us either   */
               /* Without noecho() some ugly escape
                * charachters might have been printed
                * on screen         */
   else
   {   printw("The pressed key is ");
      attron(A_BOLD);
      printw("%c", ch);
      attroff(A_BOLD);
   }
   refresh();         /* Print it on to the real screen */
       getch();         /* Wait for user input */
   endwin();         /* End curses mode        */

   return 0;
}


What I don't understand is

keypad(stdscr, TRUE);

should enable the reading of function keys but its not working...

any ideas? Confused
