Class AbegoTreeLayoutForNetbeans<N,E>

java.lang.Object

org.netbeans.api.visual.graph.layout.GraphLayout<N,E>

org.abego.treelayout.netbeans.AbegoTreeLayoutForNetbeans<N,E>

Type Parameters:

N - the node type

E - the edge type

public class AbegoTreeLayoutForNetbeans<N,E>
extends org.netbeans.api.visual.graph.layout.GraphLayout<N,E>

This GraphLayout implementation uses the abego TreeLayout library to create a more compact tree layout than provided by the standard GraphLayout code.

Usage

Assume you already have added the tree elements (nodes and edges) to a GraphScene scene and the root node is stored in root. Then you may use code similar to the following to layout the tree and display it in a dialog:

 // layout the tree
 AbegoTreeLayoutForNetbeans graphLayout = new AbegoTreeLayoutForNetbeans(root,
                100, 100, 50, 50, true);
 SceneLayout sceneLayout = LayoutFactory.createSceneGraphLayout(scene,
                graphLayout);
 sceneLayout.invokeLayoutImmediately();
 
 // display the tree in a dialog
 JScrollPane panel = new JScrollPane(scene.createView());
 JDialog dialog = new JDialog();
 dialog.setModal(true);
 dialog.setTitle(title);
 dialog.add(panel, BorderLayout.CENTER);
 dialog.setSize(800, 600);
 dialog.setVisible(true);
 dialog.dispose();
