Hallo,

what you will have to do is to provide respective ConnectionAnchor implementations for your source and target figures, which your source and target EditParts will have to provide via the methods of the NodeEditPart interface (which they have to implement as being valid source/target for connections). There is no predefined connection anchor that provides your desired behavior, but you may easily create one by subclassing AbstractConnectionAnchor. It already provides a listener mechanism, which will update the locations upon changes to the reference figure.

Cheers,
Alexander
