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 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 returns the spacing information for the menu.
If a pointer is
NULL,
the corresponding information 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.
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.
