Could you please provide me any helpful information?

Thanks in advance.

Hi Jakub.
I just do not get it. What are you giving this info for? It is to do
with resources whilst Henry might not even being touching the resources.
What if he edits a file outside of any workspace or anything else?

You're right Peter. I want to display notification if the file has been
changed from outside. Just as it works in Eclipse (I mean "File has been
changed on the file system. Do you want to load the changes?")

Well, actually, I would like to know an answer to that question myself. :-)

Look at AbstractTextEditor.sanityCheckState(IEditorInput input) (or
safelySanityCheckState()).
You can call this method from the PartListener.partActivated() method.

This already happens for free if you switch back from outside but you
need to have document provider that can detect the change. Take a look
at TextFileDocumentProvider.

This happens for free if we inherit the AbstractTextEditor. If we have a
multi-page editor and create the source page, we have to add this method
to the PartListener (see XMLMultiPageEditorPart$ActivationListener in
the webtools project).
