Hi ,
I am using the BendPointConnectionRouter to connect to two EditPart
Figures. The following is the code snippet
connection.setEndpoints(start, end);
BendpointConnectionRouter connectionRouter = new
BendpointConnectionRouter();
List<Bendpoint> list = new ArrayList<Bendpoint>();
list.add(new AbsoluteBendpoint(start.x, end.y));
connectionRouter.setConstraint(connection, list);
connection.setConnectionRouter(connectionRouter);
connection.setRoutingConstraint(list);
connectionRouter.route(connection);
But this doesnt work for me. I just get a straight line between the two
figures. Am i doing the right thing here !
Thanks in advance,
Kathir.

Hi Kathir
Where are you putting this code snippet? I assume you are putting this =
code in createFigure() in your ConnectionEditPart?
Try:
protected IFigure createFigure() {
PolylineConnection connection =3D new PolylineConnection();
BendpointConnectionRouter connectionRouter =3D new =
BendpointConnectionRouter();
connection.setConnectionRouter(connectionRouter);
return connection;
}
protected void refreshVisuals() {
super.refreshVisuals();
PolylineConnection connection =3D (PolylineConnection) =
getFigure();
ConnectionRouter connectionRouter =3D =
connection.getConnectionRouter();
List list =3D new ArrayList();
list.add(new AbsoluteBendpoint(connection.getSourceAnchor()
.getReferencePoint().x, connection.getTargetAnchor()
.getReferencePoint().y));
connectionRouter.setConstraint(connection, list);
connection.setRoutingConstraint(list);
}
Cheers...

Hi Anthony !
Thanks !
No luck on the bendpoint connection !
Actually i do all steps you mentioned inside my refreshVisuals(). I
create the connection inside my editpart.
I set the end points of the connection inside the refresh visuals every
time. and based on the endpoints my bendpoints will change.
I dont use ConnectionAnchor. Is this a must for a PolylineConnection?
I am not sure what is going wrong !
BR,
Kathir.

ok, now it works.
I created the connection using the XYAnchor instead of using the
setEndPoints() method.
