Using Python, I'm trying to write the cursor location to the lower right corner of my curses window using addstr() but I get an error. ScreenH-2 works fine but is printed on the 2nd line up from the bottom of the winddow. ScreenH-1 does not work at all. What am I doing wrong?
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
You need to substract 1 from the width as you did for the height. Otherwise the string will exceed the width of the screen.
screen.addstr(ScreenH - 1, ScreenW - 1 - cloclen, cloc, curses.color_pair(1))
