NetBeans IDE 7.3: How to extend the context menu of the members and hierarchy view?

Today i will show you how to extend the context menu of the newly redesigned members and hierarchy view in NetBeans IDE 7.3.

Plugin your action at the following extension points


and get the TreePathHandle from the Node’s lookup. Easy isn’t it? Please note that these extension points are new in NB IDE 7.3 – see the issues [1] and [2].

This allows the integration of current/future actions which react on
TreePathHandle like

  • toggle method breakpoint (when a method is selected)
  • toggle class breakpoint (when a class is selected)
  • run/debug main method (when a class with a main method is selected)
  • run/debug test (when a class with testmethods is selected or when a testmethod is selected)
  • add as profiling root (when a method is selected)
  • integration of my own “Copy FQN” plugin (i will blog about it next time)

But now a more concrete 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.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")
@ActionRegistration(displayName = "SampleAction")
    @ActionReference(path = "Navigator/Actions/Members/text/x-java", position = 1150),
    @ActionReference(path = "Navigator/Actions/Hierarchy/text/x-java", position = 1150)
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);

The result:
