If your problem is scrolling, use the toolbar buttons to navigate between changes.

Didn't completely understood what you mean by toolbar buttons...if the source content width is more than 70 (I am using a 21" monitor) I still have to scroll using the mouse...e.g. in BeycondCompare I can change the view to horizontal/vertical I am looking something like that.

Looking at the code of org.eclipse.comparator.internal.CompareEditor (which is the name of the class of the editor illustrated in your question), I do not see any indication of a different "orientation" (horizontal layout vs. vertical layout)

So, no. I do not think the current implementation allows you to compare files with a different layout.

One way to overcome your problem is to Maximize editor window during file compare, and then Restore it after compares are done. I wish Eclipse did it by default.

As to the question of orientation. I think it's more readable when you compare revisions side-by-side. That's probably why Eclipse authors did not give us an option of horizontal layout. What they could have given us were a line diff at the current cursor position.

I guess Robert was referring to Select Next/Previous Change/Difference buttons (see section Toolbar in Eclipse Help).

I'm afraid VonC is right that the current implementation doesn't support changing the layout, but there is a bug open for it so you can either provide a patch or ping guys from Eclipse Workspace Team (including me :) and ask them to fix it for you ;)
