Hi there,
This is just a observation which should probably be piggy-backed onto an current bugzilla. But I was not sure if it is directly related since most of the current ones deal with zoom features.

We noticed that a connection decorator (in this case a triangle representing a arrowhead on a connection) will rotate slightly depending on the relative position of the arrow to the feature. Hence the triangle skews slightly and the polyline connector is no longer orthogonal to the base of the triangle.

Thanks,
Joe

Hi Joe,
can you add a screenshot and the code snippet where you create connection and connection decorator?

BR,
Matthias

Hi Matthias,
Sorry it has taken me a bit to get back to this.

Here is the code snippet for creating the arrow head:
   private Polyline createArrow(GraphicsAlgorithmContainer gaContainer) {
       
        IGaService gaService = Graphiti.getGaService();
        Polygon polygon =
            gaService.createPolygon(gaContainer, new int[] { -15, 10, 1, 0, -15,
                -10 });
        polygon.setForeground(manageColor(IColorConstant.BLACK));
        polygon.setBackground(manageColor(IColorConstant.BLACK));
        polygon.setLineWidth(2);
        polygon.setFilled(true);
        return polygon;
    }


It is called from:

    public PictogramElement add(IAddContext context) {
        IAddConnectionContext addConContext = (IAddConnectionContext) context;
        IsSolvedBy addedIsSolvedBy = (IsSolvedBy) context.getNewObject();
        IPeCreateService peCreateService = Graphiti.getPeCreateService();
       
        Connection connection = peCreateService
            .createFreeFormConnection(getDiagram());
        connection.setStart(addConContext.getSourceAnchor());
        connection.setEnd(addConContext.getTargetAnchor());
        
        IGaService gaService = Graphiti.getGaService();
        Polyline polyline = gaService.createPolyline(connection);
        polyline.setLineWidth(2);
        polyline.setForeground(manageColor(IColorConstant.BLACK));
 
        link(connection, addedIsSolvedBy);

        ConnectionDecorator cd;
        cd = peCreateService
              .createConnectionDecorator(connection, false, 1.0, true);
        createArrow(cd);
        return connection;
    }

Here are the images you requested.
The straight instance:
index.php/fa/8075/0/

The crooked version. This was a user reported issue and I still cannot, completely, convince myself that it is not just my eyes playing tricks on me. But I don't drink at work...
index.php/fa/8076/0/


Thanks for all your help,
Joe

Hi, i have the same problem:

index.php/fa/13689/0/

This would be a task to be open in Bugzilla?

Sorry to revive the thread, but I was wondering if there had been any progress on this bug, or if it was still being worked on at all?

It is a problem that my editor has had for a long time, and we were wondering if it would be fixed soon.

Thanks.

Dwight,

sorry, but there is no progress on this due to limited capacity. Let's see
if we can get to this for the upcoming Luna release.
