Hi all,
I have a number of Figures that send Points to their anchors to control
the anchors' locations. The anchors move with the Figures, but when the
Figures are re-sized, the anchor positions don't expand and contract.
I've tried updating the location Points in the Figures' paintFigure()
method, but it hasn't been working. Any thoughts?
I apologize in advance if this has been asked elsewhere, but I hadn't
found it.
Matt

You should not do like that. You needn't code in figure if
your anchor extends AbstractConnectionAnchor. Because when
figure translated or moved, Figure#fireMoved() will be
called, thus listener added by AbstractConnectionAnchor
will notify listeners of connections to update. And as a
result, the connections will call the anchor's
getReferencePoint() and getLocation() again to get a newer
location.
