I am learning how to use curses and I am trying to create a simple program to start off. I am expecting this program to have a q printed in the top left corner always, then it prints the most recently pressed character in 1,1. But I'm not sure how to set the position of the cursor, which should be changed by using the curses.setsyx(y,x) function but it isn't working. Here is my program:
import curses
import sys,os
def screen_init(stdscr):
stdscr.clear()
stdscr.refresh()
stdscr.scrollok(1)
height, width = stdscr.getmaxyx()
curses.start_color()
curses.init_pair(1, curses.COLOR_CYAN, curses.COLOR_BLACK)
while True:
stdscr.addstr(0, 0, "q", curses.color_pair(1))
key = stdscr.getch()
stdscr.addstr(1, 1, chr(int(key)), curses.color_pair(1))
if key == ord('q'):
break
elif key == ord('p'):
curses.setsyx(3, 3)
curs_y, curs_x = curses.getsyx()
curses.doupdate()
stdscr.addstr(1, 1, "clicked! " + str(curs_x) + " " +
str(curs_y), curses.color_pair(1))
stdscr.refresh()
curses.endwin()
def main():
curses.wrapper(screen_init)
if (__name__ == "__main__"):
main();
Any ideas on why it isn't doing anything? When I use getsyx() it gets 3, 3 but the cursor's true position doesn't change
you can use stdscr.getyx()
and stdscr.move(y, x)
instead.
setsyx
and getsyx
affect a special workspace-screen named newscr
, which is used to construct changes sent to stdscr
when you call refresh
.
stdscr
has its own position, which is not affected by those calls.
