directory-tree

The goal of this project is to provide an efficient and convenient implementation of Java Swing JTree model with a hierarchy of a local filesystem directories (e.g. for directory chooser component).

Note: Though the model itself does not provide any builtin support for asynchronous operations, it can be built and prepopulated (via DirTreeModel.getTreePath) on any thread and then passed to the EDT.

Example:

import org.swingk.io.dirtree.DirTreeModel;
import org.swingk.io.dirtree.DefaultNodeFactory;
import org.swingk.io.dirtree.DirTreeUtils;

import javax.swing.JTree;

var model = new DirTreeModel<>(DirTreeUtils.NAME_COMPARATOR, true, true, new DefaultNodeFactory());
JTree tree = new JTree();
DirTreeUtils.configureTree(tree, model);

A demo application is provided. See org.swingk.io.dirtree.demo.Demo.

This library is packaged as a Java 9 module org.swingk.io.dirtree (with a single dependency on a system module java.desktop).

This project has no external dependencies (except JUnit 5, for testing).

Requires Java 11 or later.
