Synopsis:
|
||||
WINDOW *newpad(int nlines, int ncols);
|
||||
WINDOW *subpad(WINDOW *orig, int nlines, int ncols,
|
||||
int begy, int begx);
|
||||
int prefresh(WINDOW *win, int py, int px, int sy1, int sx1,
|
||||
int sy2, int sx2);
|
||||
int pnoutrefresh(WINDOW *w, int py, int px, int sy1, int sx1,
|
||||
int sy2, int sx2);
|
||||
int pechochar(WINDOW *pad, chtype ch);
|
||||
int pecho_wchar(WINDOW *pad, const cchar_t *wch);
|
||||
|
||||
Description:
|
||||
A pad is a special kind of window, which is not restricted by
|
||||
the screen size, and is not necessarily associated with a
|
||||
particular part of the screen. You can use a pad when you need
|
||||
a large window, and only a part of the window will be on the
|
||||
screen at one time. Pads are not refreshed automatically (e.g.,
|
||||
from scrolling or echoing of input). You can't call wrefresh()
|
||||
with a pad as an argument; use prefresh() or pnoutrefresh()
|
||||
instead. Note that these routines require additional parameters
|
||||
to specify the part of the pad to be displayed, and the location
|
||||
to use on the screen.
|
||||
|
||||
newpad() creates a new pad data structure.
|
||||
|
||||
subpad() creates a new sub-pad within a pad, at position (begy,
|
||||
begx), with dimensions of nlines lines and ncols columns. This
|
||||
position is relative to the pad, and not to the screen as with
|
||||
subwin. Changes to either the parent pad or sub-pad will affect
|
||||
both. When using sub-pads, you may need to call touchwin()
|
||||
before calling prefresh().
|
||||
|
||||
pnoutrefresh() copies the specified pad to the virtual screen.
|
||||
|
||||
prefresh() calls pnoutrefresh(), followed by doupdate().
|
||||
|
||||
These routines are analogous to wnoutrefresh() and wrefresh().
|
||||
(py, px) specifies the upper left corner of the part of the pad
|
||||
to be displayed; (sy1, sx1) and (sy2, sx2) describe the screen
|
||||
rectangle that will contain the selected part of the pad.
|
||||
|
||||
pechochar() is functionally equivalent to addch() followed by
|
||||
a call to prefresh(), with the last-used coordinates and
|
||||
dimensions. pecho_wchar() is the wide-character version.
|
||||
|
||||
Return Value:
|
||||
All functions return OK on success and ERR on error.
