Hi Stoyan,


The arrows have a setter called setSnapToBorder.

I turn this on when creating my arrow, but the snapping action is not present when the arrow is being created, only after it is created.

Can this behavior be enforced when the arrow is getting created itself? This will give a proper visual indication of what the arrow's path is going to be after creation.

I have the autoroute enabled on the flowchart.

Thanks,
Praveen

Hi Stoyan,

I tried this and it seems to give me some problem. So, I have included a trimmed down version of the code where the problem is present:

flowchart = new FlowChart();
this.getContentPane().add(flowchart);

flowchart.setArrowStyle(ArrowStyle.Cascading);
flowchart.setRouteArrows(true);
flowchart.setSnapToAnchor(SnapToAnchor.OnCreateOrModify);
flowchart.getRoutingOptions().setTriggerRerouting(RerouteArrows.WhileCreating);

So, I have the above lines in the code, and on running it, I get this exception:

On dragging from inside a box, the arrow end automatically attaches to the same box and dragging the mouse out of the box throws the above exception.

Thanks,
