java系统级的键盘和鼠标状态 [英] java system-wide keyboard and mouse state

问题描述

有没有办法在系统范围内收听鼠标和键盘事件，而不将其从系统队列中取出？

Is there a way to listen to the mouse and keyboard events system-wide without taking these out of system queue?

例如。有没有办法设置一个恶魔，让我们说，哪个会听和报告每个键盘和鼠标事件？

E.g. is there a way to set a demon, let's say, which would listen and report each and every keyboard and mouse event?

推荐答案

不可能使用纯Java。但是您可以使用JNI（Java Native Interface），它正在使用C ++编写的代码和本机编译。所以，这样你可以用C ++编写全局KeyListener，并让Java使用它。

It's not possible using pure Java. But you can use JNI (Java Native Interface), which is working on code written in C++ and natively compiled. So, this way you can write the Global KeyListener in C++ and let make Java use of it.

有一个为Linux，OS X和Windows实现的活动项目： http://code.google.com/p/jnativehook/
