在使用Python时,我试图使用addstr()将光标位置写入curses窗口的右下角,但得到了一个错误。ScreenH-2
工作正常,但打印在从风道底部向上的第二行。ScreenH-1
根本不起作用。我做错什么了?在
import curses
ScreenH = 0
ScreenW = 0
CursorX = 1
CursorY = 1
def repaint(screen):
global ScreenH
global ScreenW
global CursorX
global CursorY
ScreenH, ScreenW = screen.getmaxyx()
cloc = ' ' + str(CursorX) + ':' + str(CursorY) + ' '
cloclen = len (cloc)
screen.addstr (ScreenH - 1, ScreenW - cloclen, cloc, curses.color_pair(1));
def Main(screen):
curses.init_pair (1, curses.COLOR_WHITE, curses.COLOR_BLUE)
repaint (screen)
while True:
ch = screen.getch()
if ch == ord('q'):
break
repaint (screen)
curses.wrapper(Main)
File "test.py", line 17, in repaint
screen.addstr (ScreenH - 1, ScreenW - cloclen, cloc, curses.color_pair(1));
_curses.error: addstr() returned ERR
您需要像对高度所做的那样从宽度中减去1。否则字符串将超过屏幕的宽度。在
您还可以使用
insstr
代替addstr
:这将阻止滚动,从而允许您打印到最后一行的最后一个字符
