I've spent a few days playing with the sample ShapeDiagrams (code by
Elias, article by Bo http://www.eclipse.org/articles/Article-GEF-diagram-editor/s hape.html)
and for the most part I'm very happy with what I can do. However when
it comes to making connections I have a lot of trouble getting
selecting the source and target. What do I need to implement to play
with this behaviour? I would be delighted with any hint. It appears
that TalendOpenStudio has the sort of behaviour I'm looking for so
even a hint as too which classes to study should be enough.
