.Sh SYNOPSIS
|
|
.Fd #include <menu.h>
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Xr menu 3
|
|
provides a terminal independent menu system using the
|
|
.Xr curses 3
|
|
library. Before using the
|
|
.Xr menu 3
|
|
functions the terminal must be set up by
|
|
.Xr curses 3
|
|
using the
|
|
.Fn initscr
|
|
function or similar. Programs using
|
|
.Xr menu 3
|
|
functions must be linked with the
|
|
.Xr curses 3
|
|
library.
|
|
.Pp
|
|
The
|
|
.Xr menu 3
|
|
library provides facilties for defining menu items, placing a menu on the
|
|
terminal screen, assign pre and post change operations and setting the
|
|
attributes of both the menu and it's items.
|
|
.Sh Defining default attributes for menus and items
|
|
The
|
|
.Xr menu 3
|
|
library allows any settable attribute or option of both the menu and item
|
|
objects to be defined such that any new menu or item automatically inherits
|
|
the value as default. Setting the default value will not affect any item or
|
|
menu that has already been created but will be applied to subsequent objects.
|
|
To set the default attribute or option the set routine is passed a NULL
|
|
pointer in the item or menu parameter when calling the set routine. The
|
|
current default value can be retrieved by calling the get routine with a
|
|
NULL pointer for the item or menu parameter.
