It's useful * for applications where the cursor is not used, since it reduces * the need for cursor motions. If possible, the cursor is made * invisible when this option is enabled. * * wsetscrreg() sets a scrolling region in a window; "top" and * "bot" are the line numbers for the top and bottom margins. If * this option and scrollok() are enabled, any attempt to move off * the bottom margin will cause all lines in the scrolling region * to scroll up one line. setscrreg() is the stdscr version. * * idlok() and idcok() do nothing in PDCurses, but are provided for * compatibility with other curses implementations. * * raw_output() enables the output of raw characters using the * standard *add* and *ins* curses functions (that is, it disables * translation of control characters). * * Return Value: * All functions return OK on success and ERR on error. * * Portability X/Open BSD SYS V * clearok Y Y Y * idlok Y Y Y * idcok Y - 4.0 * immedok Y - 4.0 * leaveok Y Y Y * setscrreg Y Y Y * wsetscrreg Y Y Y * scrollok Y Y Y * raw_output - - - */ /**************************************************************************** * Included Files ****************************************************************************/ #include "curspriv.h" /**************************************************************************** * Public Functions ****************************************************************************/ int clearok(WINDOW *win, bool bf) { PDC_LOG(("clearok() - called\n")); if (!win) { return ERR; } win->_clear = bf; return OK; } int idlok(WINDOW *win, bool bf) { PDC_LOG(("idlok() - called\n")); return OK; } void idcok(WINDOW *win, bool bf) { PDC_LOG(("idcok() - called\n")); } void immedok(WINDOW *win, bool bf) { PDC_LOG(("immedok() - called\n")); if (win) { win->_immed = bf; } } int leaveok(WINDOW *win, bool bf) { PDC_LOG(("leaveok() - called\n")); if (!win) { return ERR; } win->_leaveit = bf; curs_set(!bf); return OK; } int setscrreg(int top, int bottom) { PDC_LOG(("setscrreg() - called: top %d bottom %d\n", top, bottom)); return wsetscrreg(stdscr, top, bottom); } int wsetscrreg(WINDOW *win, int top, int bottom) { PDC_LOG(("wsetscrreg() - called: top %d bottom %d\n", top, bottom)); if (win && 0 <= top && top <= win->_cury && win->_cury <= bottom && bottom < win->_maxy) { win->_tmarg = top; win->_bmarg = bottom; return OK; } else { return ERR; } } int scrollok(WINDOW *win, bool bf) { PDC_LOG(("scrollok() - called\n")); if (!win) { return ERR; } win->_scroll = bf; return OK; } int raw_output(bool bf) { PDC_LOG(("raw_output() - called\n")); SP->raw_out = bf; return OK; }
