How do I show my node’s properties in the Properties view?

I want to have the properties of my custom nodes displayed in the Properties view when they are selected in my tree view. How do I go about doing that?

Listen for changes in the selected nodes in the [http://bits.netbeans.org/dev/javadoc/org-openide-explorer/org/openide/explorer/ExplorerManager.html ExplorerManager], and set the activatedNodes property on the parent [[DevFaqWindowsTopComponent| TopComponent]] which contains your tree view:

public class MyComponent extends TopComponent implements PropertyChangeListener {
    private ExplorerManager explorerManager;
    public MyComponent() {
        explorerManager = new ExplorerManager();
    public void propertyChange(PropertyChangeEvent evt) {
        if (evt.getSource() == explorerManager &&
                ExplorerManager.PROP_SELECTED_NODES.equals(evt.getPropertyName())) {

Note that the example above is not a complete TopComponent implementation with a tree view and nodes. It is simply demonstrating how to have the selected node’s properties shown in the Properties view.
