我正在写eclipse插件。我有 MultiPageEditor，其中有 5 页。在第一页有一个扩展 GraphicalEditor(geEx) 的编辑器，在第二页有 2(logicInputEditor, logicOutputEditor) GroovyEditor 的 org.codehaus.groovy.eclipse.editor.GroovyEditor)。geEx 正在处理一个文件（例如 first.qwe），而 logicEditors 正在处理另外两个文件（in.groovy、out.groovy）。在 geEx 中有一个代码：
@Override
public void commandStackChanged(EventObject event) {
firePropertyChange(IEditorPart.PROP_DIRTY);
super.commandStackChanged(event);
}
当我首先编辑文件时。qwe MultiPageEditor 知道某些内容已被修改并标记它并允许保存文件 - 一切都很好。
我将侦听器添加到 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 GroovyEditor 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，但控制台上也会打印异常。所以-它按我的意愿工作，但是每次用户在编辑器中键入某些内容时抛出和捕获异常很慢而且通常很糟糕。

问题是 - 我该如何解决这个问题？我应该如何向 MultiPageEditor 发送“消息”，GroovyEditor 之一是“脏”？
