FIxedConnectionAnchor

How to stop Connection from moving when Nodes are moved?

for this to take place we need to understand the concept of fixedconnectionAnchor. Try to extend the class AbstractConnectionAnchor and override the mehods getLocation() and the getOwner() method to suit to your needs.

Then go to the editpart you wish the connection to stick to and just write the following code -

public ConnectionAnchor getTargetConnectionAnchor(ConnectionEditPart connEditPart) {
  if (fixedAnchor == null) {
    fixedAnchor = new FixedConnectionAnchor(getNodeFigure());
    getNodeFigure().addAncestorListener(fixedAnchor);
  }
 return fixedAnchor;
} 

public ConnectionAnchor getTargetConnectionAnchor(Request request) {
  if (fixedAnchor == null) {
      fixedAnchor = new FixedConnectionAnchor(getNodeFigure());
      getNodeFigure().addAncestorListener(fixedAnchor);
     }
 return fixedAnchor;
}
