mitem_current - set and get current_menu_item


#include <menu.h>

int set_current_item(MENU *menu, ITEM *item);
ITEM *current_item(const MENU *menu);

int set_top_row(MENU *menu, int row);
int top_row(const MENU *menu);

int item_index(const ITEM *item);


The function set_current_item sets the current item (the item on which the menu cursor is positioned). current_item returns a pointer to the current item in the given menu.

The function set_top_row sets the top row of the menu to show the given row (the top row is initially 0, and is reset to this value whenever the O_ROWMAJOR option is toggled). The item leftmost on the given row becomes current. The function top_row returns the number of the top menu row being displayed.

The function item_index returns the (zero-origin) index of item in the menu's item pointer list.


current_item returns a pointer (which may be NULL). It does not set errno.

top_row and item_index return ERR (the general curses error value) if their menu parameter is NULL.

set_current_item and set_top_row return one of the following:

The routine succeeded.
Routine detected an incorrect or out-of-range argument.
Routine was called from an initialization or termination function.
No items are connected to the menu.
System error occurred (see errno(3)).


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


The header file <menu.h> automatically includes the header file <curses.h>.


These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.

The SVr4 menu library documentation specifies the top_row and index_item error value as -1 (which is the value of ERR).
