Custom Connector

[Joseph]

Hi,

I am very new to Syncfusion Diagrams. I would like to know one thing that it is possible to create a custom connector (that has to act like other connectors) in symbol designer and use in the drawing application?
The connector I want to create is similar to Directed Link but there will one small filled cycle near arrow head and whenever length or size of the link is changed, cycle size has not been changed.


Thanks,

joseph

Hi Joseph,

Thank you for choosing Syncfusion products.

The requirement which you have mentioned is not possible in symbol designer. Because each symbol in symbol designer is considered as a Group. The normal behaviour of the Group is, while changing size of the parent node, the child node under the group also change.

The normal behavior of the Group is, while changing size of the parent node, the child node under the group also change. So we can achieve your requirement via code not in symbol designer.

Hi Gowri,

If so, could you please post some sample code? So that I can reference it and get idea what to do.

Hi Joseph,

We can achieve your requirement by changing the LineConnector.HeadDecorator.DecoratorShape or LineConnector.TailDecorator.DecoratorShape as below. There are more number of DecoratorShape's available for our need. Please make use of it.

Syncfusion.Windows.Forms.Diagram.LineConnector ln = new Syncfusion.Windows.Forms.Diagram.LineConnector(PointF.Empty, new PointF(10, 5));
ln.HeadDecorator.DecoratorShape = DecoratorShape.CircleReverseArrow;
rect.CentralPort.TryConnect(ln.HeadEndPoint);
rect1.CentralPort.TryConnect(ln.TailEndPoint);
diagram1.Model.AppendChild(ln);

The above code will create LineConnector with circle head. Circle wont affect when we change the line size.

Gowri

Hi Gowri,

Thanks for reply.
But I think DecoratorShape.CircleReverseArrow is combination of small circle and reverse arrow (arrow tail). What I want to create is small circle with forward arrow (arrow head).


Thanks,

Hi Joseph,

We cannot create the linetool which one you are expecting because not possible to create more than one symbol without grouping.
