A tree whose nodes may be checked (e.g. the widget usually found in software installers, that allows to select which features to install/uninstall). If a node has some child of different checking status is greyed. You can use the same constructors of JTree to instantiate a new CheckboxTree Example from a TreeNode:

 DefaultMutableTreeNode root = new DefaultMutableTreeNode("root"); root.add(new DefaultMutableTreeNode("child A")); root.add(new DefaultMutableTreeNode("child B")); CheckboxTree CheckboxTree = new CheckboxTree(root);

Example from a TreeModel:

 DefaultTreeModel dtm = new DefaultTreeModel(root); CheckboxTree CheckboxTree = new CheckboxTree(root);

Default constructor (useful for gui builders):

 CheckboxTree CheckboxTree = new CheckboxTree();

Then you can set the checking propagation style:

 CheckboxTree.getCheckingModel().setCheckingMode(TreeCheckingModel.CheckingMode.SIMPLE); CheckboxTree.getCheckingModel().setCheckingMode(TreeCheckingModel.CheckingMode.PROPAGATE); CheckboxTree.getCheckingModel().setCheckingMode(TreeCheckingModel.CheckingMode.PROPAGATE_PRESERVING_CHECK); CheckboxTree.getCheckingModel().setCheckingMode(TreeCheckingModel.CheckingMode.PROPAGATE_PRESERVING_UNCHECK);

You can also set the model at a later time using:

 CheckboxTree.setModel(aTreeModel);

There are two methods that return the paths that are in the checking set:

 TreePath[] tp = CheckboxTree.getCheckingPaths(); TreePath[] tp = CheckboxTree.getCheckingRoots();

You can also add/remove a listener of a TreeCheckingEvent in this way:

 CheckboxTree.addTreeCheckingListener(new TreeCheckingListener() { public void valueChanged(TreeCheckingEvent e) { System.out.println("Checked paths changed: user clicked on " + (e.getLeadingPath().getLastPathComponent())); } });
