public class FileTreeModel

Object
FileTreeModel

A tree model representing the file system as a whole, notice that this class returns absolute file names which would result in an unreadable tree. To fix this you can create a Tree object and override functionality such as the childToDisplayLabel method like this:

Tree fileTree = new Tree(new FileTreeModel(true)) { protected String childToDisplayLabel(Object child) { if (((String) child).endsWith("/")) { return ((String) child).substring(((String) child).lastIndexOf('/', ((String) child).length() - 2)); } return ((String) child).substring(((String) child).lastIndexOf('/')); } };
