Customize line connector's decorator in Diagram

To add custom decorator shape for the connectors, Load() method of Decorator class is used. Load() method is used to load new custom graphics path.

C#

OrthogonalConnector link = new OrthogonalConnector(rec1.PinPoint, rec2.PinPoint,
MeasureUnits.Pixel);
link.HeadDecorator.DecoratorShape = DecoratorShape.Filled45Arrow;
link.TailDecorator.Load(this.CreateCustomDecorator());
this.diagram1.Model.AppendChild(link);
private GraphicsPath CreateCustomDecorator()
{
GraphicsPath gpPath = new GraphicsPath();
gpPath.AddEllipse(0, 0, 10, 20);
return gpPath;
}
 

 

VB

Dim link As OrthogonalConnector = New OrthogonalConnector(rec1.PinPoint, rec2.PinPoint,
MeasureUnits.Pixel)
link.HeadDecorator.DecoratorShape = DecoratorShape.Filled45Arrow
link.TailDecorator.Load(Me.CreateCustomDecorator())
Me.diagram1.Model.AppendChild(link)
Private Function CreateCustomDecorator() As GraphicsPath
Dim gpPath As GraphicsPath = New GraphicsPath()
gpPath.AddEllipse(0, 0, 10, 20)
Return gpPath
End Function
