reacting to a resouce going out of synch [message #192780]

Hi,
I have a custom editor opened on a file. The file contains a reference
to a second file. I want the editor to update when the second file
changes on disk. What strategy can I follow?

I thought I could "listen" for resources going out of synch, but I don't
see such functionality.

I could have a thread polling isOutOfSynch(), but I should also make
sure that any action the user might perform on the editor will validate
that the resource is not out of synch. Note that the resource is not the
file the editor is opened on, but a second one referred by such file.

So the question is: how do I intercept any user action in an editor to
verify whether my resource is out of synch?

Thanks,
Roberto

You can register with the workspace for any resource changes, take a look at
IFile.getWorkspace().addResourceChangeListener()
