.SH NAME
|
|
\fBmitem_current\fR - set and get current_menu_item
|
|
.SH SYNOPSIS
|
|
\fB#include <menu.h>\fR
|
|
.br
|
|
int set_current_item(MENU *menu, const ITEM *item);
|
|
.br
|
|
ITEM *current_item(const MENU *menu);
|
|
.br
|
|
int set_top_row(MENU *menu, int row);
|
|
.br
|
|
int top_row(const MENU *menu);
|
|
.br
|
|
int item_index(const ITEM *item);
|
|
.br
|
|
.SH DESCRIPTION
|
|
The function \fBset_current_item\fR sets the current item (the item on which
|
|
the menu cursor is positioned). \fBcurrent_item\fR returns a pointer to the
|
|
current item in the given menu.
|
|
|
|
The function \fBset_top_row\fR 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
|
|
\fBO_ROWMAJOR\fR option is toggled). The item leftmost on the given row
|
|
becomes current. The function \fBtop_row\fR returns the number of the top menu
|
|
row being displayed.
|
|
|
|
The function \fBitem_index\fR returns the (zero-origin) index of \fIitem\fR in
|
|
the menu's item pointer list.
|
|
.SH RETURN VALUE
|
|
\fBcurrent_item\fR returns \fBNULL\fR on error.
|
|
|
|
\fBtop_row\fR and \fBitem_index\fR return \fBERR\fR (the general \fBcurses\fR
|
|
error value) on error.
|
|
|
|
\fBset_current_item\fR and \fBset_top_row\fR return one of the following:
|
|
.TP 5
|
|
\fBE_OK\fR
|
|
The routine succeeded.
|
|
.TP 5
|
|
\fBE_SYSTEM_ERROR\fR
|
|
System error occurred (see \fBerrno\fR).
|
|
.TP 5
|
|
\fBE_BAD_ARGUMENT\fR
|
|
Routine detected an incorrect or out-of-range argument.
|
|
.TP 5
|
|
\fBE_BAD_STATE\fR
|
|
Routine was called from an initialization or termination function.
|
|
.TP 5
|
|
\fBE_NOT_CONNECTED\fR
|
|
No items are connected to the menu.
|
|
.SH SEE ALSO
|
|
\fBcurses\fR(3X), \fBmenu\fR(3X).
|
|
.SH NOTES
|
|
The header file \fB<menu.h>\fR automatically includes the header file
|
|
\fB<curses.h>\fR.
|
|
.SH PORTABILITY
|
|
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 \fBtop_row\fR and
|
|
\fBindex_item\fR error value as -1 (which is the value of \fBERR\fR).
