[英]get updated screen size in python curses
I'm using the curses library in python and the only way I know to get the dimensions of the screen is with curses.LINES
and curses.COLS
. 我在python中使用curses库,并且我知道获取屏幕尺寸的唯一方法是使用
curses.LINES
和curses.COLS
。 However, those values never get updated, even when a "KEY_RESIZE"
key is read, like in the following example: 但是,即使读取了
"KEY_RESIZE"
键,这些值也永远不会更新,如以下示例所示:
import curses
f = open("out.log", "w")
def log(msg):
f.write(msg)
f.flush()
stdscr = curses.initscr()
curses.noecho()
curses.cbreak()
stdscr.keypad(True)
while True:
stdscr.clear()
stdscr.refresh()
key = stdscr.getkey()
log(key)
if key == "KEY_RESIZE":
log("{} {}".format(curses.LINES, curses.COLS))
if key == "q":
break
stdscr.keypad(False)
curses.nocbreak()
curses.echo()
curses.endwin()
f.close()
In my output file out.log
, I can see that when I resize the curses window, it correctly writes KEY_RESIZE
y, but the value of curses.LINES
and curses.COLS
doesn't get updated. 在我的输出文件
out.log
,可以看到当我调整curses窗口的大小时,它正确地写入了KEY_RESIZE
y,但是curses.LINES
和curses.COLS
的值没有得到更新。 What I am missing? 我缺少什么?
使用rows, cols = stdscr.getmaxyx()
代替curses.LINES
和curses.COLS
