altgr不能与jnativehook一起使用？

Question

它仅用于测试目的。

我试图改变代码的一些部分，并阅读api文档。 开始时我添加了“typedC + = e.getKeyChar（）;”它看起来像登录altgr键，但后来不再了。

如何更改它让工作altgr键？

感谢

什么操作系统？在Linux上有2.0的一些已知问题，但它们将在2.1中得到修复。如果还有其他问题，您可能需要报告一个错误。请包括您确切的键盘布局，型号和语言。还提供了有关按下什么键，观察到的行为和预期行为的详细信息。我只知道如何使用美式键盘，所以我不确定所有的Alt-Gr语言/区域特定键，蒙版和锁都是如何工作的。
