Anchor Points [message #174839]

How can I control where, around the bounds of a rounded rectangle (or
other shape), connection points are placed?

My goal is to avoid having overlapping connection lines in and out from
nodes.

Thanks in advance,
Johan

Nobody ever had this problem with rectilinear PolyConnectionEx lines?

Hi you should in the EditPart that is supposed to be connected to
another EditPart add two functions

public ConnectionAnchor getSourceConnectionAnchor(ConnectionEditPart
arg0) the same for getTargetConnectionAnchor

There you should return a ConnectionAnchor that could be for example
ChopboxAnchor this algorithm makes connection points around the node in
the middle of each side.
Best Regards Surayya
