Python curses how to change cursor position with curses.setsyx(y,x)?

Question

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 aq 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

Answer 1

您可以改用stdscr.getyx()和stdscr.move(y, x) 。

Answer 2

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.
