box

[xlordt]

well i have been working on this for a bit now but i cant seem to see why its not printing out the box with choices.. can anyone help

  int startx = 0;
  int starty =0;
 char *choices[]  = { "choice 1",
                                 "choice 2",
				  "choice 3",
				  "choice 4",
				   "Exit",
 };

 int n_choices = sizeof(choices) / sizeof(char *);
 void print_menu(WINDOW *menu_win, int highlight);

int main()
{

  WINDOW *menu_win;
  int highlight = 1;
  int choice = 0;
  int c;
  initscr();
  clear();
  cbreak();
  noecho();
  startx = ( 80 - WIDTH) / 2;
  starty = ( 24 - HEIGHT) / 2;

  menu_win = newwin(HEIGHT, WIDTH, startx, starty);
  keypad(menu_win, TRUE);
  mvprintw(0,0 ," Please select your choice");
  refresh();
  print_menu(menu_win, highlight);
  while (1)
  {
     c = wgetch(menu_win);
        switch (c)
	  {
	     case KEY_UP:
	         if( highlight == 1)
		     highlight = n_choices;
		     else
		          --highlight;
			  break;
	       case KEY_DOWN:
	              if( highlight == n_choices )
		             highlight = 1;
			 else
			     ++highlight;
			     break;
	        case 10:
		         choice = highlight;
			 break;
	        default:
		     mvprintw(24,0, "You have pressed = %3d hope fully we can get %c",c, c);
		     refresh();
		     break;
		 }
 	print_menu(menu_win, highlight);
	     if (choice != 0)
	          break;
	}
	 mvprintw(23, 0, "you have choces %d with %c\n",choice, choices[choice - 1] );
        clrtoeol();
	refresh();
	endwin();
	return 0;
  }
     void print_menu(WINDOW *menu_win, int highlight)
   {
      int x, y, i;
      x = 2;
      y = 2;
         box(menu_win, 0, 0);
	   for (i=0; i<n_choices; ++i)
	   {
	     if (highlight == i+1)
	     {
	        wattron(menu_win, A_REVERSE);
		  mvwprintw(menu_win, y,x,"%s",choices[i]);
		  wattroff(menu_win, A_REVERSE);
		  }
		else
		  mvwprintw(menu_win, y, x, "%s", choices[i]);
		  ++y;
        }
	   wrefresh(menu_win);
}

i hope i can figure this out cause im a newbie and i think i will do better if i knew what am i doing wrong here ... thanx

I had to make a few additions to get it to compile, but the menu displayed fine for me. I added:

#include <curses.h>

#define WIDTH 80
#define HEIGTH 24

Also, if you are having trouble linking, be sure to add the '-lcurses' switch to gcc.
