NAME


border_set, wborder_set, box_set, hline_set, whline_set, mvhline_set, mvwhline_set, vline_set, wvline_set, mvvline_set, mvwvline_set - create curses borders or lines using complex characters and renditions

SYNOPSIS


#include <curses.h>

int border_set( const cchar_t *ls, const cchar_t *rs, const cchar_t *ts, const cchar_t *bs, const cchar_t *tl, const cchar_t *tr, const cchar_t *bl, const cchar_t *br ); int wborder_set( WINDOW *win, const cchar_t *ls, const cchar_t *rs, const cchar_t *ts, const cchar_t *bs, const cchar_t *tl, const cchar_t *tr, const cchar_t *bl, const cchar_t *br); int box_set( WINDOW *win, const cchar_t *verch, const cchar_t *horch); int hline_set( const cchar_t *wch, int n); int whline_set( WINDOW *win, const cchar_t *wch, int n); int mvhline_set( int y, int x, const cchar_t *wch, int n); int mvwhline_set( WINDOW *win, int y, int x, const cchar_t *wch, int n); int vline_set( const cchar_t *wch, int n); int wvline_set( WINDOW *win, const cchar_t *wch, int n); int mvvline_set( int y, int x, const cchar_t *wch, int n); int mvwvline_set( WINDOW *win, int y, int x, const cchar_t *wch, int n);

DESCRIPTION


The border_set and wborder_set functions draw a border around the edges of the current or specified window. These functions do not change the cursor position, and do not wrap.

Other than the window, each argument is a complex character with attributes:

ls - left side, rs - right side, ts - top side, bs - bottom side, tl - top left-hand corner, tr - top right-hand corner, bl - bottom left-hand corner, and br - bottom right-hand corner.

If any of these arguments is zero, then the corresponding default values (defined in curses.h) are used instead:

WACS_VLINE, WACS_VLINE, WACS_HLINE, WACS_HLINE, WACS_ULCORNER, WACS_URCORNER, WACS_LLCORNER, and WACS_LRCORNER.

box_set(win, verch, horch); is a shorthand for the following call:

wborder_set(win, verch, verch, horch, horch, NULL, NULL, NULL, NULL);

The *line_set functions use wch to draw a line starting at the current cursor position in the window. The line is at most n characters long or as many as fit into the window. The current cursor position is not changed.

The hline_set, mvhline_set, mvwhline_set, and whline_set functions draw a line proceeding toward the last column of the same line.

The vline_set, mvvline_set, mvwvline_set, and wvline_set functions draw a line proceeding toward the last line of the window.

NOTES


Note that border_set, hline_set, mvhline_set, mvvline_set, mvwhline_set, mvwvline_set, and vline_set may be macros.

RETURN VALUES


Upon successful completion, these functions return OK. Otherwise, they return ERR.

Functions using a window parameter return an error if it is null.
