Question

我正在尝试编写双击CTRL后执行某些内容的脚本。首次双击后效果很好，但后来我得到了这个错误。此外，如果我在定时器执行函数triger之后一次按CTRL，我将得到相同的错误。

import pythoncom, pyHook, threading

press = False

def triger():
    global press
    press=False

def something():
    print 'hello'

def OnKeyboardEvent(event):
    global press
    if event.Key=='Lcontrol':
        if press:
            something()
            press = False
        else:
            press=True
            threading.Timer(1,triger).start()


hm = pyHook.HookManager()
hm.KeyDown = OnKeyboardEvent
hm.HookKeyboard()
pythoncom.PumpMessages()

错误：

hello

根据documentation，必须在KeyboardEvent函数结束时“返回True”。这是它的样子。

def OnKeyboardEvent(event):
    global press
    if event.Key=='Lcontrol':
        if press:
            something()
            press = False
        else:
            press=True
            threading.Timer(1,triger).start()
            print 'waiting'
    return True

threading.Timer TypeError：需要一个整数
