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.

Synopsis:
|
|
int touchwin(WINDOW *win);
|
|
int touchline(WINDOW *win, int start, int count);
|
|
int untouchwin(WINDOW *win);
|
|
int wtouchln(WINDOW *win, int y, int n, int changed);
|
|
bool is_linetouched(WINDOW *win, int line);
|
|
bool is_wintouched(WINDOW *win);
|
|
|
|
Description:
|
|
touchwin() and touchline() throw away all information about
|
|
which parts of the window have been touched, pretending that the
|
|
entire window has been drawn on. This is sometimes necessary
|
|
when using overlapping windows, since a change to one window
|
|
will affect the other window, but the records of which lines
|
|
have been changed in the other window will not reflect the
|
|
change.
|
|
|
|
untouchwin() marks all lines in the window as unchanged since
|
|
the last call to wrefresh().
|
|
|
|
wtouchln() makes n lines in the window, starting at line y, look
|
|
as if they have (changed == 1) or have not (changed == 0) been
|
|
changed since the last call to wrefresh().
|
|
|
|
is_linetouched() returns TRUE if the specified line in the
|
|
specified window has been changed since the last call to
|
|
wrefresh().
|
|
|
|
is_wintouched() returns TRUE if the specified window
|
|
has been changed since the last call to wrefresh().
|
|
|
|
Return Value:
|
|
All functions return OK on success and ERR on error except
|
|
is_wintouched() and is_linetouched().
