Question

我希望创建一个在PyHook中帮助记录鼠标点击位置的应用程序。在高水平，我想

将鼠标单击绑定到方法或功能
当用户点击鼠标时，取消勾选鼠标
在我的程序中做一些事情，稍后重新绑定鼠标（hookMouse）并等待再次点击

使用pumpMessages块不是一种选择。如果我知道如何向pumpMessages发送退出消息，这可能是另一种选择。我试图使用pythoncom.PumpWaitingMessages（），这似乎是一个完美的ft，但每次单击鼠标时都会导致异常。我一直无法调试原因。

def onclick(event):
    global hm
    try:
        print (str(event.Position))
        hm.UnhookMouse()
    except:
        pass


# create a hook manager
hm = pyHook.HookManager()


# watch for all mouse events
hm.SubscribeMouseLeftDown(onclick) 
# set the hook
hm.HookMouse()

# wait forever
pythoncom.PumpWaitingMessages()

错误，正如所见：

Python 3.4.0 (v3.4.0:04f714765c13, Mar 16 2014, 19:25:23) [MSC v.1600 64 bit (AMD64)] on win32

    raise Empty
queue.Empty

During handling of the above exception, another exception occurred:

pyHook - PumpWaitingMessages抛出execption而PumpMessages没有
