我无法从Eclipse配置中删除Subclipse.
由于m2eclipse项目放弃了对Subclipse的支持,我决定切换到Subversive.
所以我卸载了Subclipse,然后使用About Eclipse - > Installation Details - > Uninstall方法安装Subversive.现在,当我进入任何与Team相关的选项/任务/首选项时,有两个可用的SVN选项(一个用于Subversive,一个用于Subclipse)使生活变得混乱.
抓住.metadata字符串的工作区文件夹后,subclipse我可以看到配置仍然充斥着对Subclipse的引用:

上面的所有项目现在都与SVN断开连接.显然有些参考文献如usagedata并不重要,但我更担心的是XML文件.手动浏览并删除与Subclipse相关的所有标签/属性是否安全？我觉得这种做法可能是不明智的.
有没有人知道如何在不丢失工作空间的情况下消除Subclipse的所有痕迹？关于我可能做错了什么的任何提示？在切换到Subversive之前,我是否应该手动断开所有SVN项目？
我正在尝试基于a创建自定义UI JWindow,以便选择要共享的屏幕区域.我已经扩展JWindow并添加了代码以使其可调整大小并使用"切出"窗口的中心AWTUtilities.setWindowShape().
当运行代码时,我正在经历闪烁,因为窗口在负x和y方向上调整大小,即向上和向左.似乎正在发生的是在更新组件之前调整窗口大小并绘制窗口.下面是代码的简化版本.运行时,顶部面板可用于向上和向左调整窗口大小.窗口的背景设置为绿色,以清楚显示我不想显示的像素的位置.
编辑:改进代码以使用a正确地塑造窗口,ComponentListener并在底部添加虚拟组件以进一步说明闪烁(也更新了屏幕截图).

SpecialAnalysis currentAnalysis = new SpecialAnalysis(params_here);
我正在尝试实现一个"取消"按钮,它将对象的isCancelled布尔值设置为true.实现这个的正确Java方法是什么？
while (currentAnalysis == null) {
}
currentAnalysis.cancel();
该方法冻结了程序,因为它似乎进入了计算效率低下的循环.这是我可以使用的情况Object.wait()吗？
我目前的糟糕/半成功的解决方案是:
while (currentAnalysis == null) {
Thread.sleep(500);
}
currentAnalysis.cancel();
谢谢!
JXTA 项目还活跃吗？我正在寻找一个好的开源点对点解决方案，找到了 JXTA 文章，但是“jxta.org”不起作用，它还活着吗？或者把它移到其他地方了？
