【问题描述】:
我正在 Windows 上使用 python 开发自定义街机启动器。我想选择系统和游戏,然后启动模拟器 - 并需要某个组合键来杀死模拟器。在使用随机应用程序进行测试时,我的所有关键挂钩都可以工作,但是当我实际启动模拟器(例如 Nestopia)时,我的关键挂钩无法触发。我目前正在使用 RegisterHotKey,它获取事件但不获取热键。任何人都知道如何安装足够低的东西以在 Nestopia 之前实际获得活动?这是我的代码:
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
