public class IlvDoubleSplineLinkImage
extends IlvDoubleLinkImage

IlvDoubleSplineLinkImage represents the connection between two nodes in a grapher; the link is displayed as a spline with two curves. For more information about specialized link objects, see IlvLinkImage.

The default values for an IlvDoubleSplineLinkImage instance are as follows:

• foreground: Color.black
• line width: 0f
• end cap: IlvStroke.CAP_SQUARE

Example

The following code example shows how to use an IlvDoubleSplineLinkImage in a simple Java application:

   IlvGraphic node1, node2;
   IlvGrapher grapher = new IlvGrapher();
   IlvDoubleSplineLinkImage link;
   
   //Create new ellipse node and add it to the grapher.
   node1 = new IlvEllipse(new IlvRect(30,10,50,50), true, false);
   grapher.addNode(node1,false);
   
   //Add a new rectangular node to the grapher.
   node2 = new IlvRectangle(new IlvRect(220,90,50,50), false, true);
   grapher.addNode(node2, 2, true);
   
   //Link the two nodes and add them to a grapher.
   link = new IlvDoubleSplineLinkImage(
              node1, 
              node2,
              IlvDoubleLinkImage.VerticalLink, 
              true);
   grapher.addLink(link,true);

About Graphic Objects

IlvDoubleSplineLinkImage is a custom graphic object, that is, a subclass of IlvGraphic. Graphic objects are controlled using an IlvManager instance and displayed using one or more IlvManagerView instances in a Java Swing application. For information about generic features for graphic objects, see IlvGraphic.

Constructor Detail

IlvDoubleSplineLinkImage

public IlvDoubleSplineLinkImage(IlvGraphic from,
                                IlvGraphic to,
                                boolean oriented)

Creates a new link image.

Parameters:

from - the origin object.

to - the destination object.

oriented - if oriented is true then an arrow is drawn at the destination point.

public IlvDoubleSplineLinkImage(IlvGraphic from,
                                IlvGraphic to,
                                int orientation,
                                boolean oriented)

Creates a new link image.

Parameters:

from - the origin object.

to - the destination object.

orientation - the valid values for this may be IlvDoubleLinkImage.VerticalLink or IlvDoubleLinkImage.HorizontalLink. It specifies the direction the link takes upon leaving the from node.

oriented - if oriented is true then an arrow is drawn at the destination point.
