鼠标跟踪守护程序 [英] Mouse tracking daemon

问题描述

我需要写一些东西使用Cocoa来表示原始鼠标移动数据。最好，应用程序只是一个运行的一个守护进程，将数据传递给另一个应用程序可以访问事件的套接字服务器。

I need to write something using Cocoa to surface raw mouse movement data. Optimally, the app would just be a little daemon that would run, passing the data to a socket server which another application could tap into to gain access to the events.

任何人都指出我在方法和工具方面的正确方向？我现在不知道从哪里开始。

Can anyone point me in the right direction with regard to approach and tools? I am not even sure where to begin with this right now.

推荐答案

另一个简单的方法是添加全局事件监视器（仅限10.6）：

The other simple way to do this is to add a global event monitor (10.6 only, however):

id eventHandler = [NSEvent addGlobalMonitorForEventsMatchingMask:NSMouseMovedMask handler:^(NSEvent * mouseEvent) {
  NSLog(@"Mouse moved: %@", NSStringFromPoint([mouseEvent locationInWindow]));
}];

然后当您完成跟踪时，您会：

Then when you're done tracking, you do:

[NSEvent removeMonitor:eventHandler];
