I'd like to prevent a ViewPart from being closed by the user if a certain
condition is true. To that effect, I'd like to be notified if a view is about to
be closed and to veto that close. 

There are notification hooks in the framework which will tell me that a view had
been closed, or is about to close, but I can't veto them. Worse, any type of
activity to free resources must be currently done in that event handler, since
after all event handlers are run, the view *will* be freed or closed.

The editor framework does something like this already. If a resource has been
modified, a dialog pops up and if you choose to cancel the operation (the close)
, the editor will not close. 

I wanna do the same for views (ViewPart subclasses) and for Editors in a more
general way then the dirty -> save -> quit pattern.



It seems that this type of functionality is missing from the UI framework.
