Имя (Name)
set_menu_format, menu_format - set and get menu sizes
Синопсис (Synopsis)
#include <menu.h>
int set_menu_format(MENU *menu, int rows, int cols);
void menu_format(const MENU *menu, int *rows, int *cols);
Описание (Description)
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.
