Description Jean-Michel Lemieux CLA 2003-07-24 14:56:41 EDT 
3.0 M2
I've come accross another issue with our refactoring of the Synchronize view
away from the DiffTreeViewer. We can no longer support the next/previous
workflows where you could navigate differences between different panes in the
compare editor input.
The importance of this is outlined in the following Bug 20106.

We would need a way of selecting the next change and then knowing when the
start/end has been reached to that we can step forwards/backwards in the
Synchronize View. I've experimented with CompareNavigator but it wasn't really
designed for that.

Comment 2 Andre Weinand CLA 2003-08-25 10:52:17 EDT 
Released new (experimental) API to Compare HEAD (first appearance in N20030826).

- added new interface org.eclipse.compare.ICompareNavigator with single method 
   boolean selectChange(boolean next). Returns true if at end (beginning).
- for now you can get this interface for an CompareEditorInput via
   getAdapter(ICompareNavigator).
- for an example please see org.eclipse.compare.NavigationAction

Let me know if you need more/different functionality
