altgr不能与jnativehook一起工作？

Question

这只是为了测试目的。

我试着修改了代码的某些部分，同时也阅读了api-docs。在begin中，我添加了"typedC += e.getKeyChar();“，它看起来像是记录altgr-键，但后来就不再是了。

如何改变它让工作altgr-键？

谢谢

什么操作系统？Linux上的2.0有一些已知的问题，但这些问题将在2.1中修复。如果有任何其他问题，您可能需要报告一个错误。请包括您的确切键盘布局，型号和语言。还提供了有关按下的键、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国键盘，所以我不确定所有Alt-Gr语言/区域特定的键、口罩和锁是如何工作的。
