如何调试Eclipse中JComboBox的actionEvent的处理并避免锁定窗口系统？

Question

我编写了一个带有Swing GUI的Eclipse插件.为了调试插件,我生成了一个辅助Eclipse工作区.然后,我在actionPerformed从JComboBox中选择菜单项时由方法调用的方法上设置断点.

当我从JComboBox中选择一个项目时,我的GUI会冻结,显示整个JComboBox的菜单.表示Eclipse调试工作空间的KDE图标会在遇到断点时闪烁.不幸的是,在这一点上,我的KDE会话已被清除.我可以移动鼠标,但选择任何窗口或图标都没有效果(包括闪烁的Eclipse调试图标).我无法在KDE中做任何事情,所以我通过常规终端窗口来杀掉日食过程.这使我能够再次在KDE中做事.

我该怎么做才能避免KDE 4.5.5中的这种锁定并调试我的代码？以下是一些相关的Java和Eclipse属性:

Answer 1

如下所述:http://bugs.sun.com/view_bug.do？bad_id = 6714678,解决方法是通过向-Dsun.awt.disablegrab=trueVM参数添加:来禁用在X11平台上获取抓取.
