Hello, I am trying to watch for changes occuring in my default java editor
and am having some trouble figuring out how to add a listener and what
type of listener to add. I have the following code which will give me the
handle to the current active
org.eclipse.jdt.internal.ui.javaeditor.CompilationUnitEditor . Where abouts
can I hook into an IEditorPart to be notified of text level changes?

IEditorPart e = TemplatePlugin.getActiveEditor();
IContentOutlinePage outlinePage = (IContentOutlinePage)
e.getAdapter(IContentOutlinePage.class);
if (outlinePage != null) {
// editor wishes to contribute outlinePage to content outline view
System.out.println("the current selection is:
"+outlinePage.getSelection());
}

Basically what I am after is notification when users are editing a file
that they have opened up in the default java editor. So I thought that if
I could get the "CompilationUnitEditor" that I should be able to somehow
watch or listen to it. But I cannot see any thing that will allow me to do
this.

Your help on this issue is much appreciated, I have tried asking this
question before and no one seems interested, a reply would be nice.

thanks in advance ........ Reagan

You need to get the IDocument associated with the editor and add your
liseteners to the document.

You can do:

("approved way")
IDocumentProvider provider = editor.getDocumentProvider();
IEditorInput input = editor.getEditorInput();
IDocument doc = provider.getDocument(input);

Once you have the document, you can add all sorts of listeners to it.
