Hi,
I am using the eclipse' TextEditor and I wish to handle the case wherein the
editor's Document content is replaced by a call to 'set' as follows:
getDocumentProvider().getDocument(input).set(text);
This call sets the editor state to dirty. However, I wish to handle this
case specifically and set some flag that would help my logic condition.
I wish to ask the group whether it is possible to catch the content replace
of the editor's Document?
Thanks in advance and appreciate your help.
Regards,
Prashanto

Hi Guys,
Good news - I cracked it. What I did was I made my editor which extends
TextEditor listen to document changes as follows:
getDocumentProvider().getDocument(getEditorInput()).addPreno tifiedDocumentListener(this);
The method addDocumentListener was not of much help as it does not allow us
to register a second listener
Then I implemented my logic in the method 'documentChanged(DocumentEvent
event) '.
This did the trick.
Thanks anyways,
Prashanto

Why not? You should be able to register as many listeners as you like
using IDocument.addDocumentListener(...).
Note that addPrenotifiedDocumentListener(...) is not for public use (see
its Javadoc).

Thanks for pointing it out. I had misunderstood its functionality and
confused it with another API that I had read. Its very nice of you to point
it out even when I had a working solution.
Thanks for correcting me.
