setDestination function do not attach to anchor point

My question would be why setDestination function does not attach to anchor point?


Code (Javascript)
Select All
   var gatewayAnchorPoints = [new AnchorPoint(50, 0),
        new AnchorPoint(100, 50),
        new AnchorPoint(50, 100),
        new AnchorPoint(0, 50)];

    gateway.setAnchorPattern(gatewayAnchorPoints);

diagram.addItem(gateway);

destinationNode.incomingLinks[1].setDestination(gateway, gateway.getAnchorFromIndex(1));


diagram.routeAllLinks();


This kindof place link at correct anchor point, but does not attach to it. Maybe you would know why?

In documentaiton i can find "ReassignAnchorPoints" method, but can't find it in source...is this something that ought to be?

If links are reacreated it works just fine. Is there a method, to reatach link to node anchor point?

That second argument seems to be for internal use (you have the code I guess). If you are using it, you'll need to also call link.destinationConnection.addLinkToNode();

Otherwise if you need to set explicit anchor point, try this -

link.setDestination(gateway);
link.setDestinationAnchor(1);

Slavcho

Yeah you are right, but it seems here is some math problem....i got the desired behaviour modifying source...but can't find yet why it does attach near anchor point, but not on anchoir.


fix was, adding that method you mentioned, calling Shapes updateFromEndPoint, and invalidate();

but if they are attached to the same anchor point, they appear attached near that point (~5px apart)

routeAllLinks pulls apart link segments when they would overlap, maybe that's what adds the distance between end points. Try setting MindFusion.Diagramming.Router.prototype.pullLinksApart = function (links) {} to see if it helps.
