在Windows上，如何安装最低级别的全局键盘钩子？

我正在使用Windows上的python自定义街机启动器。我想选择系统和游戏，然后启动模拟器 - 并且要求某个组合键杀死模拟器。我的所有关键挂钩在随机应用程序测试时都能正常工作，但是当我真正启动模拟器（例如Nestopia）时，我的关键挂钩无法启动。我目前使用RegisterHotKey，它获取事件，但不是热键。任何人都有一个想法，如何安装一些足够低的功能，以便在Nestopia之前真正获得该事件？这里是我的代码：在Windows上，如何安装最低级别的全局键盘钩子？

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
