所以我找到了解决方案,感谢这篇文章http://jroller.com/santhosh/entry/keyboard_handling_in_tablecelleditor,以及关于此问题以及如何将其应用于其他组件的一些有用的讨论http://forums.java.net/jive/thread.jspa?messageID=482236????
不完全理解解决方案这整个区域似乎是一个雷区
我还添加了这个解决方案使用 java DefaultCellEditor 在 JTable 中获得正确的编辑行为这样,当您开始使用键盘编辑字段时,现有值就会被替换,但当您双击该字段时则不会。
我的一个困惑是,我没有收到预期的关键事件,而是空的,所以我必须对此做出解释。
我已经不再使用 setSurrenderKeylines(true) 因为这会导致其他编辑器(例如简单的 textfieldeditor)出现问题
