在python curses中,如果我使用scr.subwin()绘制一个子窗口来获取带有getstr()函数的输入,如下所示
search_box = screen.subwin(3, 30, 20, 30)
search_box.clear()
search_box.box()
search_box.addstr(1, 1, "GoTo:")
search_box.refresh()
curses.echo()
new_x = int(search_box.getstr(1, 6, 20))
search_box.clear()
我决定不提供任何意见。如何逃离新的子窗口?

我已解决了我的问题,如下所示
search_box = screen.subwin(3, 30, 20, 30)
search_box.clear()
search_box.box()
in_str = "GoTo:"
val_str = ""
search_box.addstr(1, 1, in_str)
search_box.refresh()
curses.echo()
char = search_box.getch()
try:
int(chr(char))
val_str += chr(char)
except:
pass
while char != 27: # Escape Key Value
if char == 10: # Enter Key Value
new_x = int(val_str)
break
else:
search_box.clear()
search_box.box()
search_box.addstr(1, 1, in_str+val_str)
search_box.refresh()
char = search_box.getch()
try:
int(chr(char))
val_str += chr(char)
except:
if char == 127:
if len(val_str) > 0:
val_str = val_str[:-1]
