[英]How to detect curses ALT + key combinations in python
New to python here and using the curses import. 这里是python的新手,并使用curses导入。 I want to detect key combinations like ALT + F and similar.
我想检测像ALT + F和类似的关键组合。 Currently, I am using
getch()
to receive a key and then printing it in a curses window. 目前,我使用
getch()
接收密钥,然后在curses窗口中打印它。 The value does not change for F or ALT + F . F或ALT + F的值不会改变。 How can I detect the ALT key combinations?
如何检测ALT键组合?
import curses
def Main(screen):
foo = 0
while foo == 0:
ch = screen.getch()
screen.addstr (5, 5, str(ch), curses.A_REVERSE)
screen.refresh()
if ch == ord('q'):
foo = 1
curses.wrapper(Main)
Try this: 尝试这个:
import curses
def Main(screen):
while True:
ch = screen.getch()
if ch == ord('q'):
break
elif ch == 27: # ALT was pressed
screen.nodelay(True)
ch2 = screen.getch() # get the key pressed after ALT
if ch2 == -1:
break
else:
screen.addstr(5, 5, 'ALT+'+str(ch2))
screen.refresh()
screen.nodelay(False)
curses.wrapper(Main)
