Tree Customizations

To change the look of our tree, we change the DefaultTreeCellRenderer:

DefaultTreeCellRenderer renderer =

new DefaultTreeCellRenderer();

renderer.setLeafIcon(new ImageIcon

("Document.gif"));

tree.setCellRenderer(renderer);

UIManager.put("Tree.leafIcon",

new ImageIcon(”foo.gif"));

UIManager.put("Tree.openIcon",

new ImageIcon(”bar.gif"));

UIManager.put("Tree.closedIcon",

new ImageIcon(”baz.gif"));

UIManager.put("Tree.expandedIcon",

new ImageIcon(”frob.gif"));

UIManager.put("Tree.collapsedIcon",

new ImageIcon(”qux.gif"));

We can also directly change the Tree through the UIManager:
