Hi folks,

I want to develop a plugin based on the nice quick diff
functionality in eclipse. But quick diff is like a heap of
many classes and interfaces where i find it hard to
understand their coherence.

-how can you "access" the content displayed by quickdiff in
the sidebar?(i want to save this "codepieces" in a file)

-is it possible to change the UI elements of the quickdiff
"popup"? and is it possible to add some UI elements like
buttons or something like that.

-generally i would be very glad if you could show me some
code examples concerning a "reuse" of quickdiff for a
plugin or an own programm.

i've already digged my way through some compare classes but
it didn't work out...

thanks in advance!

Not directly. As a starting point, you should look at ChangeRulerColumn
in the org.eclipse.jface.text plug-in to see how it gets the ILineDiffer
instance for its editor. You can then get diff information
(ILineDiffInfo) from the ILineDiffer.

If you have your own editor, this is possible. You can create your own
LineChangeHover implementation, where you can also override
getHoverControlCreator.

Return your custom LineChangeHover from your overridden
AbstractDecoratedTextViewer.createChangeHover method.

See the above classes.
