在Windows上，如何安裝最低級別的全局鍵盤鉤子？

我正在使用Windows上的python自定義街機啓動器。我想選擇系統和遊戲，然後啓動模擬器 - 並且要求某個組合鍵殺死模擬器。我的所有關鍵掛鉤在隨機應用程序測試時都能正常工作，但是當我真正啓動模擬器（例如Nestopia）時，我的關鍵掛鉤無法啓動。我目前使用RegisterHotKey，它獲取事件，但不是熱鍵。任何人都有一個想法，如何安裝一些足夠低的功能，以便在Nestopia之前真正獲得該事件？這裏是我的代碼：在Windows上，如何安裝最低級別的全局鍵盤鉤子？

import ctypes 
import win32con 
from ctypes import wintypes 
from ctypes import byref 
user32 = ctypes.windll.user32 

class SimpleKeyboardHook: 

    def getNextId(self): 
    SimpleKeyboardHook._id += 1 
    return SimpleKeyboardHook._id 

    # modifiers is a bitmask with win32con.[MOD_SHIFT, MOD_ALT, MOD_CONTROL, MOD_WIN] 
    def waitFor(self, key, modifiers): 

    # coerce to 0 if necessary 
    modifiers = modifiers or 0 

    id = self.getNextId() 
    hk = user32.RegisterHotKey(None, id, modifiers, key) 
    print "register hotkey: ",hk 
    if not hk: 
     print "Unable to register hotkey for key ", key 
     return False 

    print "registered id", id 

    try: 
     msg = wintypes.MSG() 
     while user32.GetMessageA(byref(msg), None, 0, 0) != 0: 
     print "got message",msg.message,"which is not",win32con.WM_HOTKEY 
     if msg.message == win32con.WM_HOTKEY: 
      print "got hotkey" 
      if msg.wParam == id: 
      print "found proper hotkey" 
      return True 

     user32.TranslateMessage(byref(msg)) 
     user32.DispatchMessageA(byref(msg)) 
    finally: 
     user32.UnregisterHotKey(None, id) 

    return False 

SimpleKeyboardHook._id = 0
