NAME

SYNOPSIS

9       #include <menu.h>
10       int set_menu_win(MENU *menu, WINDOW *win);
11       WINDOW *menu_win(const MENU *menu);
12       int set_menu_sub(MENU *menu, WINDOW *sub);
13       WINDOW *menu_sub(const MENU *menu);
14       int scale_menu(const MENU *menu, int *rows, int *columns);

DESCRIPTION

17       Every  menu  has an associated pair of curses windows.  The menu window
18       displays any title and border associated with the window; the menu sub‐
19       window  displays the items of the menu that are currently available for
20       selection.
21
22       The first four functions get and set those windows.  It is  not  neces‐
23       sary  to set either window; by default, the driver code uses stdscr for
24       both.
25
26       In the set_ functions, window argument of NULL is treated as though  it
27       were stsdcr.  A menu argument of NULL is treated as a request to change
28       the system default menu window or subwindow.
29
30       The function scale_menu returns the minimum size required for the  sub‐
31       window of menu.
