Hi!
I have implemented my own anchor to handle connections to the
diamond-like figure that appears in the attached picture. The anchor
class should return one of the diamond's vertices. When I debug my
editor, the anchor class does really behave as expected. However, the
connection is not finally anchored on the right point, but in one of the
bounds' points (see attached figure). I think this behaviour is caused
by the router.
Can someone tell me how I can force the connection to use the point
returned by the anchor class?
Thanks a lot in advance!
Nicol

Take a look at the logic example where circuits have fixed anchor points.

Thanks Patrik. I have been looking at the logic example, but I could not
find the solution to my problem. Maybe it is because I did not
understand completely well how the code in the logic example works. For
example, in the example the getXConnectionAnchor methods are implemented
in the Figure class, and not in the EditPart class as I do (this
disturbs me). I have seen they also make use of a provider class, but
don't know exactly how it works. Anyhow, apart from those differences, I
think in the logic example they use the point returned by the
FixedConnectionAnchor class. And this class behaves similarly to my
DiamondAnchor class.
My problem is still the same. The anchor point is correctly calculated,
but at the end it is not used. Indeed, when creating an arc and after
selecting the source node, if I place the mouse pointer over the target
node, a temporary arc anchored at one of the vertices is correctly
drawn. However, when I press the mouse button to definitely create the
connection, a different line is drawn, as in the previous mail's
picture. Also, when I move a little the created connection, it is then
anchored at the vertex.
Hope you can help me. Thanks.

Hi, maybe you can reference org.eclipse.draw2d.EllipseAnchor and check
out diff.
Regards,
QinXian.
