Python脚本监视单击事件，但阻止它们，不允许单击事件通过

我已经编写了一个简单的程序，允许您记录点击事件并保存它们。然后，您可以再次加载保存，它将在您保存所有单击事件时再次激发这些事件。对于那些想知道的人来说，我一年前写这个程序是为了学习。当时它工作得很好。我今天想再次使用它，但它已经不能正常运行了

我启动程序，选择选项1，它调用selectAndSavePoints方法。它等待我按下s键开始，然后继续监视单击事件。问题是，它会阻止他们。我可以看到单击事件的位置写在控制台中，但当我在任务栏中单击我的资源管理器图标打开它时，它没有打开，因为单击事件被劫持，而不是被监视，并被允许传递到Windows操作系统

我尝试通过复制loadAndExecutePoints方法中的click方法并将其放置在全局coordsToClick变量声明上方的MonitorMouseClicks方法中来修复此问题。然后在onclick方法中调用click方法再次手动单击它。当我运行此程序时，它会注册第一次单击，我可以看到它再次被记录，然后程序应该为我手动单击它，但该进程随后会挂起。按alt+f4、ctrl+break或taskkilling则程序不起作用。我必须重新启动计算机才能使命令行窗口消失。我不知道这里发生了什么

pyHook模块可以在这里下载。我下载了pyHook‑1.5.1‑cp35‑cp35m‑win_amd64.whl文件，然后可以使用此命令安装该文件

pip install pyHook‑1.5.1‑cp35‑cp35m‑win_amd64.whl

顺便说一下，我正在使用python 3.5.4。

您需要将onKeyboardEvent（

monitorkeypress

）和onMouseEvent（

MonitorMouseClicks

）的返回值设置为

True

，这是一个正常调用，如果它是

False

，事件将被拦截

def MonitorKeyPresses(_hookManager):
    global coordsToClick
    def onpress(event):
        if event.Key == "P":
            del coordsToClick[-1]
        return True
...

def MonitorMouseClicks(_hookManager):
    global coordsToClick
    def onclick(event):
        coordsToClick.append(event.Position)
        print(event.Position)
        return True

（顺便说一句，您不需要重新启动计算机。右键未被阻止。您可以右键单击控制台并右键单击关闭。）

谢谢您的回答。这确实是问题所在。我按照您的建议将return0更改为returntrue，从而解决了这个问题。当我尝试手动单击时，我也意识到了问题所在，它变得非常滞后：我在一个单击事件的事件处理程序中执行了一次单击，因此这导致了一个无限循环，导致了滞后的感觉。非常感谢吴德雷克，我真的很感谢你的回答！
