Return of Marilyn Monroe
I'm rewriting the world famous Marilyn Monroe sample, using the various improvements/simplifications that have occurred since the time I first wrote it years ago—OutlineView instead of BeanTreeView, ChildFactory instead of Children.Keys, and the JDK 6 for-loop instead of the old iterators.
The result looks as follows:
If you want to take a look at it, especially if you want to learn about OutlineView, get it here:

Note that I haven't added the cut/copy/delete actions yet. So, right now the sample only shows how to create nodes and properties and how to display those in an OutlineView.
To me, the most interesting thing is how the property gets the current Movie object:
Property[] props = new Property[]{
new ReviewProperty(em.getExploredContext().getLookup().lookup(Movie.class))
};
outlineView1.setProperties(props);
That's possible because when the MovieNode is created, it adds the current Movie object into the Lookup, which is then available to the ExplorerManager:
public MovieNode(Movie item) {
super(Children.LEAF, Lookups.singleton(item));
this.movie = item;
setDisplayName(item.getTitle());
setIconBaseWithExtension("/org/demo/marilyn/resources/marilyn.gif");
}
Slightly more advanced version of the above, using the CheckableNode class:
What's interesting about the above is that I now have three modules: the "Marilyn" display window, the "Selected Movies" window, and the API consisting of the domain objects shared between the other two. Whenever a movie is selected, it is added to the InstanceContent (a dynamic travel bag of objects placed in the application's context). The "Selected Movies" window listens to the context for the introduction of movies into it. At that point, the method for returning the title is called on the movie object, which is then added to the text area in the "Selected Movies" window.

Thanks for the project ! How do you define a dependency on ConvertAsProperties? Is there an extra Jar file to include? (org.netbeans.api.settings.ConvertAsProperties)

You need to be using some recent dev build of NetBeans IDE 6.7, which is where I developed the sample and which includes that JAR. It relates to a new annotation for handling persistence of topcomponents.

@Geertjan: do you know a way to remove the "..." button from the review column?

How do you change the text of the first column header from "Node"?

Hi Geertjan, could you please post the code for the Video Store (Return of Marilyn Monroe). I managed to get the same behavior as shown in the example, but I don't like my code. Maybe I get some ideas from your code.
Thanks Markus
