Document

Creates a tree node with no parent, no children, but which allows children, and initializes it with the specified user object.

Usage

From source file:TreeIconDemo.java

public TreeIconDemo() {
    super(new GridLayout(1, 0));

    // Create the nodes.
    DefaultMutableTreeNode top = new DefaultMutableTreeNode("The Java Series");
    createNodes(top);//w w  w . j ava 2s .co  m

    // Create a tree that allows one selection at a time.
    tree = new JTree(top);
    tree.getSelectionModel().setSelectionMode(TreeSelectionModel.SINGLE_TREE_SELECTION);

    // Set the icon for leaf nodes.
    ImageIcon leafIcon = createImageIcon("images/middle.gif");
    if (leafIcon != null) {
        DefaultTreeCellRenderer renderer = new DefaultTreeCellRenderer();
        renderer.setLeafIcon(leafIcon);
        tree.setCellRenderer(renderer);
    } else {
        System.err.println("Leaf icon missing; using default.");
    }

    // Listen for when the selection changes.
    tree.addTreeSelectionListener(this);

    // Create the scroll pane and add the tree to it.
    JScrollPane treeView = new JScrollPane(tree);

    // Create the HTML viewing pane.
    htmlPane = new JEditorPane();
    htmlPane.setEditable(false);
    initHelp();
    JScrollPane htmlView = new JScrollPane(htmlPane);

    // Add the scroll panes to a split pane.
    JSplitPane splitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT);
    splitPane.setTopComponent(treeView);
    splitPane.setBottomComponent(htmlView);

    Dimension minimumSize = new Dimension(100, 50);
    htmlView.setMinimumSize(minimumSize);
    treeView.setMinimumSize(minimumSize);
    splitPane.setDividerLocation(100); // XXX: ignored in some releases
    // of Swing. bug 4101306
    // workaround for bug 4101306:
    // treeView.setPreferredSize(new Dimension(100, 100));

    splitPane.setPreferredSize(new Dimension(500, 300));

    // Add the split pane to this panel.
