How do I add an action to the context menu of the members or hierarchy view?

Since 7.3 ([1], [2]) it is possible to extend the context menu of the newly redesigned members and hierarchy view.

Plugin your action at the following extension points


Then you get the "TreePathHandle" from the Node’s lookup.

A more or less complete example:

package de.markiewb.netbeans.sample.extendMembersAndHierarchyView;

import java.util.ArrayList;
import java.util.List;
import static javax.swing.Action.NAME;
import javax.swing.JMenuItem;
import javax.swing.JOptionPane;
import org.netbeans.api.java.source.TreePathHandle;
import org.openide.awt.*;
import org.openide.nodes.Node;
import org.openide.util.HelpCtx;
import org.openide.util.NbBundle;
import org.openide.util.actions.CookieAction;
import org.openide.util.actions.Presenter;

@ActionID(category = "Edit",
	id = "de.markiewb.netbeans.sample.extendMembersAndHierarchyView.SampleAction")
	displayName = "SampleAction")
    @ActionReference(path = "Navigator/Actions/Members/text/x-java", position = 1150),
    @ActionReference(path = "Navigator/Actions/Hierarchy/text/x-java", position = 1150),
    @ActionReference(path = "Menu/File", position = 0)
 * Shows the usage of the extensionpoints of the context menu in the members and
 * hierarchy views. This is new to NetBeans 7.3. See

public final class SampleAction extends CookieAction implements Presenter.Popup {
    public SampleAction() {
	putValue(NAME, "Hello TreePathHandle(s)");

    public String getName() {
	return "Hello TreePathHandle(s)";

    public JMenuItem getPopupPresenter() {
	return new JMenuItem(this);

    public HelpCtx getHelpCtx() {
	return null;

    protected boolean enable(Node[] activatedNodes) {
	//.. use tph from lookup in node
	for (Node node : activatedNodes) {
	    if (null != node.getLookup().lookup(TreePathHandle.class)) {
		return true;
	return false;

    protected int mode() {
	return CookieAction.MODE_ALL;

    protected Class[] cookieClasses() {
	return new Class[]{Node.class};

    protected void performAction(Node[] nodes) {

	List<TreePathHandle> treePathHandles = new ArrayList<TreePathHandle>();
	for (Node node : nodes) {

	//show all treePathHandles
	JOptionPane.showMessageDialog(null, "Hello\n" + treePathHandles);
