key - NCurses 和 ESC、ALT 键

Question

我的NCurses有问题...我需要处理所有按键，例如Esc、Alt+F 等问题是代码相似......即:

<小时/>

Esc - 27

<小时/>

Alt+A - 27 65

<小时/>

作为示例，Alt+[key] 组合有双代码，与 Esc 键类似 ...有什么想法如何处理吗？

这是一个Python示例:

key = self.screen.getch()
if key == ord('q'): # quit
    go = False
elif key == 27: # Esc or Alt
    # Don't wait for another key
    # If it was Alt then curses has already sent the other key
    # otherwise -1 is sent (Escape)
    self.screen.nodelay(True)
    n = self.screen.getch()
    if n == -1:
        # Escape was pressed
        go = False
    # Return to delay
    self.screen.nodelay(False)
