Hi Jim,

I added a modified description of my original post to the top of the
example: http://www.vtk.org/Wiki/VTK/Examples/Cxx/Broken/Graphs/SelectedVertices

FYI, when the link contains "Broken", the only way to get to the
example is from the "Broken" section
(http://www.vtk.org/Wiki/VTK/Examples/Cxx#Broken.2FMissing_Examples_.28Please_write.2Ffix_me.21.29)
so there should be no reasonable expectation by a viewer that it
should work :) haha. Please feel free to adopt some of these broken
examples as you have time!

What I am trying to do is simply get a list (or output) the IDs of the
vertices that the user selects. Exactly like this:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Picking/HighlightSelectedPoints
but with a graph.

Thanks,

David
