Hi all,
I have an rcp application that use the ide open editor to edit external file
....
if I have dirty editor I will get the right message asking to save before
the application closes ...
what I don't wont is to find the editor opened again when the application is
restarted ...
where do I need to add the listener to check if there are still opened
editors before everything gets closed...
I have tried in the stop (Activator - abstractui plugin) with no result ...
probably I should play somewhere in the Application ... but I guess it will
be to late there to get some available page and from there list the editors
and close it ...
so what I would love is to be able to close the application and reopened it
again with NO EDITOR opened ...
thanks
Kar

In your WorkbenchAdvisor::initialize method, call
configurer.setSaveAndRestore(false). This will disable the workbench
saving the state when existing.

You can try to open all the editor as Wim said in his message.
Or you can access the memento directly
IPath path = WorkbenchPlugin.getDefault().getDataLocation();
path = path.append("workbench.xml");
File stateFile = path.toFile();
FileInputStream input = new FileInputStream(stateFile);
BufferedReader reader = new BufferedReader(
new InputStreamReader(input, "utf-8")); //$NON-NLS-1$
IMemento memento = XMLMemento.createReadRoot(reader);
and delete all editor references under tag IWorkbenchConstants.TAG_EDITOR

After the memento have been saved, you can access the memento file and
delete the whole editor node. You don't need do it at the closing stage
if you can't find the right place, but do it in pre-startup or wherever
fit to your requirements. The deleting just need be done before the
workbench tried to restore the editors.
But remember as what Paul said, assessing the memento file is kinds of
hacking way.

I did check yesterday a bit better and the saveState is actually empty when
I start closing the editors ... probably the editor registry doesn't get
correctly updated when the shutdown process as already started ... and
that's why even if I close them they will be reopened afterwards.
so I guess I will clean up the memento on the startup phase avoiding even to
close the editors as they will be closed anyway during the editor dispose.
I know that this will probably change with new releases but for now I guess
this is the only solution I have got left.
thanks u all guys
