NAME    [Toc]    [Back]

       menu_win - make and break menu window and subwindow associations

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

       Every  menu  has an associated pair of curses windows.  The menu window
       displays any title and border associated with the window; the menu subwindow
  displays the items of the menu that are currently available for
       selection.

       The first four functions get and set those windows.  It is  not	necessary
  to set either window; by default, the driver code uses stdscr for
       both.

       In the set_ functions, window argument of NULL is treated as though  it
       were stsdcr.  A menu argument of NULL is treated as a request to change
       the system default menu window or subwindow.

       The function scale_menu returns the minimum size required for the  subwindow
 of menu.
