NAME    [Toc]    [Back]

       menu_format - set and get menu sizes

SYNOPSIS    [Toc]    [Back]

       #include <menu.h>
       int set_menu_format(MENU *menu, int rows, int cols);
       void menu_format(const MENU *menu, int *rows, int *cols);

DESCRIPTION    [Toc]    [Back]

       The function set_menu_format sets the maximum display size of the given
       menu.  If this size is too small to display all menu  items,  the  menu
       will  be made scrollable. If this size is larger than the menus subwindow
 and	the  subwindow	is  too  small	to  display  all  menu	items,
       post_menu() will fail.

       The  default format is 16 rows, 1 column.  Calling set_menu_format with
       a null menu pointer will change this default.  A  zero  row  or	column
       argument  to  set_menu_format is interpreted as a request not to change
       the current value.

       The function menu_format returns the maximum-size constraints  for  the
       given menu into the storage addressed by rows and cols.
