>> menu_spacing (3) ( Linux man: Библиотечные вызовы )
NAME
menu_spacing - Control spacing between menu items.
SYNOPSIS
#include <menu.h>
int set_menu_spacing(MENU *menu,
int spc_description,
int spc_rows,
int spc_columns);
int menu_spacing(const MENU *menu,
int* spc_description,
int* spc_rows,
int* spc_columns);
DESCRIPTION
The function set_menu_spacing sets the spacing informations for the menu.
spc_description controls the number of spaces between an item name and an item
description. It must not be larger than TABSIZE. The menu system puts in the
middle of this spacing area the pad character. The remaining parts are filled with
spaces.
spc_rows controls the number of rows that are used for an item. It must not be
larger than 3. The menu system inserts the blank lines between item rows, these lines
will contain the pad character in the appropriate positions.
spc_columns controls the number of blanks between columns of items. It must not
be larger than TABSIZE.
A value of 0 for all the spacing values resets them to the default, which is 1 for all
of them.
The function menu_spacing passes back the spacing info for the menu. If a
pointer is NULL, this specific info is simply not returned.
RETURN VALUE
Both routines return E_OK on success. set_menu_spacing may return
E_POSTED if the menu is posted, or E_BAD_ARGUMENT if one of the
spacing values is out of range.
The header file <menu.h> automatically includes the header file
<curses.h>.
PORTABILITY
These routines are specific to ncurses. They were not supported on
Version 7, BSD or System V implementations. It is recommended that
any code depending on them be conditioned using NCURSES_VERSION.
