getOriginAnchor() problem

Hi,

I use getOriginAnchor() to determine where a link is connected to it's origin node.

After applying a layout algorythm (e.g. Flowchart) the link's origin changes but getOriginAnchor() returns the same index as before.

Is this correct?

Thanks,

Chris

Set Layout.Anchoring to Reassign if the layout code should align links to anchor points. The Ignore option ignores the anchor point positions but does not remove their association with the links.

I hope that helps,
Stoyan

Hi Stoyo,

thanks again for your quick response.

Unfortunately it appears to ignore whichever anchoring value I set.

Is there any other setting which may be affecting this?

Thanks,

Chris

Hi,

Are you calling routeAllLinks() after arrange()? The routing function considers the RoutingOptions.Anchoring value.

Hi Stoyo,

here is my code:

[code]
FlowchartLayout fl = new FlowchartLayout();

fl.setIgnoreRepeatingLinks(false);
fl.setOrientation(Orientation.Auto);

fl.setAnchoring(Anchoring.Reassign);

fl.arrange(diagram);

diagram.routeAllLinks();
[/code]

Thanks,

Chris

Hi Chris,

Set it on the RoutingOptions object too and routeAll will align the links to anchor points:

diagram.getRoutingOptions().setAnchoring(Anchoring.Reassign);
diagram.routeAllLinks();

I hope that helps,
Stoyan
