From 3b77b723ca209199c8a224702812441e2196d452 Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Thu, 7 Jul 2011 15:41:53 +0200 Subject: libpayload: Add PDCurses and ncurses' libform/libmenu PDCurses provides an alternative implementation of the curses library standard in addition to tinycurses. Where tinycurses is really tiny, PDCurses is more complete and provides virtually unlimited windows and the full API. The PDCurses code is brought in "vanilla", with all local changes residing in curses/pdcurses-backend/ In addition to a curses library, this change also provides libpanel (as part of the PDCurses code), and libform and libmenu which were derived from ncurses-5.9. As they rely on ncurses internals (and PDCurses is not ncurses), more changes were required for these libraries to work. The build system is extended to install the right set of header files depending on the selected curses implementation.

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. + + Portability X/Open BSD SYS V + newpad Y - Y + subpad Y - Y + prefresh Y - Y + pnoutrefresh Y - Y + pechochar Y - 3.0 + pecho_wchar Y + +**man-end****************************************************************/ + +#include + +/* save values for pechochar() */ + +static int save_pminrow, save_pmincol; +static int save_sminrow, save_smincol, save_smaxrow, save_smaxcol; + +WINDOW *newpad(int nlines, int ncols) +{ + WINDOW *win; + + PDC_LOG(("newpad() - called: lines=%d cols=%d\n", nlines, ncols)); + + if ( !(win = PDC_makenew(nlines, ncols, -1, -1)) + || !(win = PDC_makelines(win)) ) + return (WINDOW *)NULL; + + werase(win); + + win->_flags = _PAD; + + /* save default values in case pechochar() is the first call to + prefresh(). */ + + save_pminrow = 0; + save_pmincol = 0; + save_sminrow = 0; + save_smincol = 0; + save_smaxrow = min(LINES, nlines) - 1; + save_smaxcol = min(COLS, ncols) - 1; + + return win; +} + +WINDOW *subpad(WINDOW *orig, int nlines, int ncols, int begy, int begx) +{ + WINDOW *win; + int i; + int j = begy; + int k = begx; + + PDC_LOG(("subpad() - called: lines=%d cols=%d begy=%d begx=%d\n", + nlines, ncols, begy, begx)); + + if (!orig || !(orig->_flags & _PAD)) + return (WINDOW *)NULL; + + /* make sure window fits inside the original one */ + + if ((begy < orig->_begy) || (begx < orig->_begx) || + (begy + nlines) > (orig->_begy + orig->_maxy) || + (begx + ncols) > (orig->_begx + orig->_maxx)) + return (WINDOW *)NULL; + + if (!nlines) + nlines = orig->_maxy - 1 - j; + + if (!ncols) + ncols = orig->_maxx - 1 - k; + + if ( !(win = PDC_makenew(nlines, ncols, begy, begx)) ) + return (WINDOW *)NULL; + + /* initialize window variables */ + + win->_attrs = orig->_attrs; + win->_leaveit = orig->_leaveit; + win->_scroll = orig->_scroll; + win->_nodelay = orig->_nodelay; + win->_use_keypad = orig->_use_keypad; + win->_parent = orig; + + for (i = 0; i < nlines; i++) + win->_y[i] = (orig->_y[j++]) + k; + + win->_flags = _SUBPAD; + + /* save default values in case pechochar() is the first call + to prefresh(). */ + + save_pminrow = 0; + save_pmincol = 0; + save_sminrow = 0; + save_smincol = 0; + save_smaxrow = min(LINES, nlines) - 1; + save_smaxcol = min(COLS, ncols) - 1; + + return win; +} + +int prefresh(WINDOW *win, int py, int px, int sy1, int sx1, int sy2, int sx2) +{ + PDC_LOG(("prefresh() - called\n")); + + if (pnoutrefresh(win, py, px, sy1, sx1, sy2, sx2) == ERR) + return ERR; + + doupdate(); + return OK; +} + +int pnoutrefresh(WINDOW *w, int py, int px, int sy1, int sx1, int sy2, int sx2) +{ + int num_cols; + int sline = sy1; + int pline = py; + + PDC_LOG(("pnoutrefresh() - called\n")); + + if (!w || !(w->_flags & (_PAD|_SUBPAD)) || (sy2 >= LINES) || (sy2 >= COLS)) + return ERR; + + if (py < 0) + py = 0; + if (px < 0) + px = 0; + if (sy1 < 0) + sy1 = 0; + if (sx1 < 0) + sx1 = 0; + + if (sy2 < sy1 || sx2 < sx1) + return ERR; + + num_cols = min((sx2 - sx1 + 1), (w->_maxx - px)); + + while (sline <= sy2) + { + if (pline < w->_maxy) + { + memcpy(curscr->_y[sline] + sx1, w->_y[pline] + px, + num_cols * sizeof(chtype)); + + if ((curscr->_firstch[sline] == _NO_CHANGE) + || (curscr->_firstch[sline] > sx1)) + curscr->_firstch[sline] = sx1; + + if (sx2 > curscr->_lastch[sline]) + curscr->_lastch[sline] = sx2; + + w->_firstch[pline] = _NO_CHANGE; /* updated now */ + w->_lastch[pline] = _NO_CHANGE; /* updated now */ + } + + sline++; + pline++; + } + + if (w->_clear) + { + w->_clear = FALSE; + curscr->_clear = TRUE; + } + + /* position the cursor to the pad's current position if possible -- + is the pad current position going to end up displayed?
