我正在制作一些可以模拟和读取原生输入事件的鼠标/键盘/像素类。这些是作为java.awt.Robot和JNativeHook的包装器实现的。它们旨在用作Mac上AutoHotKey或AutoIt的替代品。我在Windows 7 64位计算机上进行测试。
我的问题是，我无法弄清楚为什么JNativeHook的键盘监听器无法正常工作。我还没有去测试鼠标听众的工作情况。它可能与Swing和JNativeHook的多线程问题有关，但我没有排除库或构建版本的问题。
我的大部分代码都是直接来自示例页面。 JNativeHook使用鼠标/键盘的调试信息为Logger和控制台发送垃圾邮件，但它不会调用监听器。我使用下载页面中的最新jar以及Eclipse和最新的jdk / jre，除非安装出现了可怕的错误。
测试类
程序显示一个按钮和一个彩色面板。按下按钮，然后键入＆＃34; 1＆＃34;应该将面板的颜色更改为与鼠标光标下的像素相同。

答案 0 :(得分：0)
我将jar版本从RC3切换到Beta2，它适用于Windows。 Beta2并没有在Mac上运行，但我认为RC 2或3可以。
