Implementing A custom content compare/merge viewer [message #326652]

hi,

I want to make a compare / merge editor in my plugin which resembles the
"Compare With" functionality provided by eclipse. The difference is that my
editor will take 2 objects as input rather than 2 files and the compare
windows will contain Labels ,TextBoxes and buttons rather than just text.

How can I achieve the same effect ? I would also like to know how eclipse
has implemented "Compare With" editor.

Thank You.

Deepti,
Implementing what you want is not all that different from the files case
except that your compare inputs would not implement
IStreamContentAccessor. You will also want your ITypedElements to return
a custom type. You would then associate your contentMergeViewer with
your type and the compare framework would then know what merge viewer to
use when it encountered an input of your type.

P.S. You may fined the slides from this talk helpful

It talks mostly about comparing files but, as I said above, the non-file
case is similar.
