NAME
set_menu_opts, menu_opts_on, menu_opts_off, menu_opts - set and get menu options
SYNOPSIS
#include <menu.h> int set_menu_opts(MENU *menu, Menu_Options opts); Menu_Options menu_opts(const MENU *menu); int menu_opts_on(MENU *menu, Menu_Options opts); int menu_opts_off(MENU *menu, Menu_Options opts);
DESCRIPTION
The function set_menu_opts sets all the given menu's option bits (menu option bits may be logically-OR'ed together). The function menu_opts_on turns on the given option bits, and leaves others alone. The function menu_opts_off turns off the given option bits, and leaves others alone. The function menu_opts returns the menu's current option bits. The following options are defined (all are on by default): O_ONEVALUE Only one item can be selected for this menu. O_SHOWDESC Display the item descriptions when the menu is posted. O_ROWMAJOR Display the menu in row-major order. O_IGNORECASE Ignore the case when pattern-matching. O_SHOWMATCH Move the cursor to within the item name while pattern-matching. O_NONCYCLIC Don't wrap around next-item and previous-item, requests to the other end of the menu. O_MOUSE_MENU If user clicks with the mouse and it does not fall on the currently active menu, push KEY_MOUSE and the MEVENT data back on the queue to allow processing in another part of the calling program.
RETURN VALUE
Except for menu_opts, each routine returns one of the following: E_OK The routine succeeded. E_SYSTEM_ERROR System error occurred (see errno(3)). E_POSTED The menu is already posted.
