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 ExplorerManager, and set the activatedNodes property on the parent TopComponent which contains your tree view:
public class MyComponent extends TopComponent implements PropertyChangeListener {
private ExplorerManager explorerManager;
public MyComponent() {
explorerManager = new ExplorerManager();
explorerManager.addPropertyChangeListener(this);
}
public void propertyChange(PropertyChangeEvent evt) {
if (evt.getSource() == explorerManager &&
ExplorerManager.PROP_SELECTED_NODES.equals(evt.getPropertyName())) {
setActivatedNodes(explorerManager.getSelectedNodes());
}
}
}
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.
