spacing(3MENU) Library calls spacing(3MENU)
NAME
set_menu_spacing, menu_spacing - set and get 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 information for the menu.
Its parameters provide the description and the size (in rows and
columns).
spc_description
controls the number of spaces between an item name and an item
description. It must not be larger than TABSIZE. The menu sys-
tem 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 returns the spacing information for the menu.
If a pointer is NULL, the corresponding information is simply not re-
turned.
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.
PORTABILITY
These routines are specific to ncurses. They were not supported on Ver-
sion 7, BSD or System V implementations. It is recommended that any
code depending on them be conditioned using NCURSES_VERSION.
