Examples of prefuse.data.Tree.addChild()

prefuse.data.Tree.addChild()
Add a child node to the given parent node. An edge between the two will also be created. @param parent the parent node id (node table row number) @return the added child node id

        t.getNodeTable().addColumns(LABEL_SCHEMA);
        
        Node r = t.addRoot();
        r.setString(LABEL, "0,0");
        
        Node left = t.addChild(r);
        left.setString(LABEL, "1,0");
        Node right = t.addChild(r);
        right.setString(LABEL, "1,1");
        
        deepHelper(t, left, b, d1-2, true);
