public class IlvCompositeLink extends IlvPolylineLinkImage implements IlvGraphicBag, IlvComposite
IlvCompositeLink
represents a link between two nodes that can
be decorated with IlvGraphic
instances.
This class uses an IlvLinkImage
instance variable for link
rendering. For more information about specialized link graphic objects, see
IlvLinkImage.
If the IlvCompositeLink
has a rendering link
(see getLink()
), all rendering values such as color, line width,
end cap and line join are controlled by the rendering link.
The following code example shows how to use an
IlvCompositeLink
in a simple Java application:
IlvGrapher grapher = new IlvGrapher(); IlvRectangle origin = new IlvReliefRectangle(new IlvRect(10, 10, 40, 40)); origin.setBackground(Color.lightGray); IlvRectangle dest = new IlvReliefRectangle(new IlvRect(250, 120, 40, 40)); dest.setBackground(Color.lightGray); grapher.addNode(origin, false); grapher.addNode(dest, false); // Creates the link responsible for the rendering IlvLinkImage link = new IlvDoubleLinkImage(origin, dest, false); IlvCompositeLink clink = new IlvCompositeLink(origin, dest, false); clink.setLink(link); clink.setLineWidth(5); clink.setForeground(Color.decode("#40BFBD")); grapher.addLink(clink, true); // Creates a plinth rectangle with a label IlvCompositeGraphic plinth = new IlvCompositeGraphic(); plinth.setLayout(new IlvCenteredLayout(new Insets(4, 10, 4, 10))); IlvRectangle rect = new IlvReliefRectangle(new IlvRect(0, 0, 40, 40)); rect.setBackground(Color.red); plinth.setChildren(0, rect); IlvZoomableLabel name = new IlvZoomableLabel(new IlvPoint(), "Paris", false); plinth.setChildren(1, name); //Adds the plinth to the link clink.setChildren(0, plinth); clink.setConstraints(0, new IlvAttachmentConstraint( IlvAttachmentLocation.CenterPostOrderFirst, IlvLinkAttachmentLocation.MiddleLink)); //Creates a stack of small rectangles IlvCompositeGraphic stacker = new IlvCompositeGraphic(); stacker.setLayout(new IlvStackerLayout()); // Creates a tiny blue rectangle IlvRectangle r1 = new IlvRectangle(new IlvRect(0, 0, 10, 10)); r1.setBackground(Color.blue); r1.setForeground(Color.blue); r1.setFillOn(true); stacker.setChildren(0, r1); // Creates a tiny red rectangle IlvRectangle r2 = new IlvRectangle(new IlvRect(0, 0, 10, 10)); r2.setBackground(Color.red); r2.setForeground(Color.red); r2.setFillOn(true); stacker.setChildren(1, r2); // Creates a tiny green rectangle IlvRectangle r3 = new IlvRectangle(new IlvRect(0, 0, 10, 10)); r3.setBackground(Color.green); r3.setForeground(Color.green); r3.setFillOn(true); stacker.setChildren(2, r3); // Adds the stack of rectangles clink.setChildren(1, stacker); // IlvLinkAttachmentLocation.NearFromLink --> hotSpot, // IlvLinkAttachmentLocation.FromLink --> anchor clink.setConstraints(1, new IlvAttachmentConstraint( IlvLinkAttachmentLocation.NearFromLink, IlvLinkAttachmentLocation.FromLink));

IlvCompositeLink
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.

:
the base text direction is inherited from the

:
the base test direction is determined from the text
that is displayed according to the standard Bidi
algorithm, if the text contains at least one character
with a strong left-to-right or right-to-left direction.
If the text doesn't contain any character with a strong
direction, the real text direction is determined from
