如何在Python中检测curses ALT +组合键

Question

这里是python的新手，并使用curses导入。我想检测像ALT + F和类似的组合键。目前，我使用getch()接收密钥，然后将其打印在curses窗口中。该值不会更改为F或ALT + F。如何检测ALT组合键？

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) 

Answer 1

试试这个：

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)
