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  parameter  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.   The
   spc_rows  parameter  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.   The  spc_columns  parameter  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.

   ncurses(3NCURSES), curses_variables(3NCURSES), menu(3MENU).

NOTES

   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.
