ETI menus

Two kinds of menus: single- or multi-valued

Menus are of two kinds:


Single-valued menus
from which the user may select only one item

Multi-valued menus
from which the user may select one or more items
By default, every menu is single-valued. To create a multi-valued menu, you turn off menu option O_ONEVALUE using function set_menu_opts or menu_opts_off. These functions are treated in ``Setting and fetching menu options''.

Menus of both types always have a current item. With single-valued menus, you determine the item selected by noting the current item. With multi-valued menus, you determine all items selected by applying function item_value to each menu item and noting the value returned. Most menu functions pertain to menus whether they are single- or multi-valued. Function set_item_value, however, may be used only with multi-valued menus.
