Eclipse插件开发 - 使用许多文件，将MultiPageEditor标记为脏抛出异常

标签： java exception eclipse-plugin

我正在编写eclipse插件。我有MultiPageEditor，其中我有5页。在第一页上有一个扩展GraphicalEditor（geEx）的编辑器，第二个有2个（logicInputEditor，logicOutputEditor）GroovyEditor的org.codehaus.groovy.eclipse.editor.GroovyEditor）。 geEx正在处理一个文件（例如first.qwe）和  logicEditors正在处理其他2个文件（in.groovy，out.groovy）。在  geEx有一个代码：




     @Override
                public void commandStackChanged(EventObject event) {
                        firePropertyChange(IEditorPart.PROP_DIRTY);
                        super.commandStackChanged(event);
                }

当我首先编辑文件时.q我们MultiPageEditor知道有什么东西  被修改并标记它并允许保存文件 - 一切都是  细

我将监听器添加到GrooveEditors：




     logicInputEditor.addPropertyListener(new IPropertyListener() {
                                @Override
                                 public void propertyChanged(Object source, int propId) {
                                         if (propId == IEditorPart.PROP_DIRTY){
                                                 firePropertyChange(IEditorPart.PROP_DIRTY);
                                         }
                                 }
                         });

我无法覆盖commandStackChanged函数，因为GrooveEditor没有实现CommandStackListener。

每次我在GroovyEditors中编辑某些内容时，MultiPageEditor都会将其状态更改为脏 - 这就是我想要的，但也会在控制台上打印异常。所以 - 它正如我想要的那样工作，但每次用户在编辑器中输入某些内容时，抛出和捕获异常都很慢并且通常很糟糕。

问题是 - 我如何解决这个问题？我应该如何向MultiPageEditor发送'message'，其中一个GroovyEditors是“脏”的？

1 个答案:

答案 0 :(得分：2)

终于解决了 - 问题不在我的代码中，而是在GroovyEditor中 - 如果项目性质是Java项目性质（可能Groovy项目本质也会起作用）一切都很好，否则GroovyEditor抛出异常。我已经向Groove Editor问题跟踪器报告了错误，它已经解决了，所以在下一个版本中一切都应该没问题。现在唯一的解决方案是将java项目性质添加到项目的性质中。
