Hi,

can anyone help me to customize a ManhattanConnection Router.
I have written a GEF Edtitor with some Edit Parts an Connections. I use the
ManhattanConnectionRouter. So far all works fine.
But as my EditParts have fixed positions and the user should only define
which connections he needs, I whant to refine the ManhattanRouting a little
bit ;-)
Just whant to add some smal edges for better look.

My code is now very simple. Where can I influence the routig path?

Thanks for help
Ralph

public class AssociationEditPart extends AbstractConnectionEditPart {
PolylineConnection polylineConnection;
protected IFigure createFigure() {
polylineConnection = new PolylineConnection();
polylineConnection.setTargetDecoration(new PolygonDecoration());
ManhattanConnectionRouter manhattanConnectionRouter= new
ManhattanConnectionRouter();
polylineConnection.setConnectionRouter( manhattanConnectionRouter);
return polylineConnection;
}

protected void createEditPolicies() {
installEditPolicy(EditPolicy.CONNECTION_ENDPOINTS_ROLE, new
ConnectionEndpointEditPolicy());

installEditPolicy(EditPolicy.CONNECTION_ROLE, new
ConnectionEditPolicy() {
protected Command getDeleteCommand(final GroupRequest request) {
return new AssociationDeleteCommand((Association)
getModel());
}
});
}

in the meantime I found out that is very simple to write a own
connectionRouter
Here a simple example for a ConnectionRouter with fixed Points:

import org.eclipse.draw2d.*;
import org.eclipse.draw2d.geometry.*;
public class MyConnectionRouter extends AbstractRouter {

public void route(Connection connection) {
PointList points = connection.getPoints();
points.removeAllPoints();

points.addPoint(new Point(100,100));
points.addPoint(new Point(120,100));
points.addPoint(new Point(120,120));

connection.setPoints(points);

}
}
