Hi All,
This is about handling deleted files in Eclipse workspace. My
requirement is, I have my own Resource navigator and need to show the
deleted files in RED color. That means, once we delete the file the
corresponding resource change event will be fired to the listeners and the
listeners will handle the resource change event. For delete event case, we
will not have the file physically and will get the state of the IFile from
the last saved state. If then as per my requirement, I have to show the
same IFile node in a resource navigator tree though the file is not
physically present. I tried to touch the ResourceChangeListener interface,
where we will get the ResouceDelta of the deleted IFile. But it's not
working out. Can any one help me out in this? Main point is , I should not
have my own java object to replace deleted IFile, instead I should be able
to play with the same IFile.
Thanks,
Chandra M

Chandra,
Things like IFile instances are handles and they don't necessarily need
to correspond to an existing resource. That's why there is an exists()
method. But of course the parent IFolder won't know about your desire
to show an IFile that doesn't exactly exist anymore so I don't know how
you are specializing the navigator to show what you desire. And of
course if you try to open an editor for a file that doesn't exists, the
editor won't like that either. You need to be more explicit about what
aspect of resource change listening isn't working out to get help with that.

Phantom resources may be of some use for what you're trying to do. Have a
look at IResource's javadoc. There is also pluggable filesystems, can
potentially be helpful as well.
Cheers,
