The Visual Tool includes a TreeView with a graphic for each item. In recent SDKs, these graphics no longer appear. I have attempted to boil the problem down to this program:


import javafx.application.Application;
import javafx.builders.SceneBuilder;
import javafx.builders.StageBuilder;
import javafx.builders.VBoxBuilder;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.TreeItem;
import javafx.scene.control.TreeView;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

/**

public class DeleteMe extends Application {
    public static void main(String[] args) {
        launch(args);
    }

    @Override public void start(Stage stage) throws Exception {
        TreeItem<Label> root = new TreeItem<Label>(new Label("Root"));
        TreeView<Label> tree = new TreeView<Label>(root);
        Label label = new Label("Hello");
        TreeItem<Label> item = new TreeItem<Label>(label);
        String imageUrl = getClass().getClassLoader().getResource("javax/swing/plaf/basic/icons/JavaCup16.png").toString();
        Image image = new Image(imageUrl);
        ImageView imageView = new ImageView(image);
        item.setGraphic(imageView);
        root.getChildren().add(item);
        VBox box = VBoxBuilder.create().children(tree).build();
        Scene scene = SceneBuilder.create().height(200).width(200).root(box).build();
        StageBuilder.create().scene(scene).visible(true).applyTo(stage);
    }
}

I am not completely sure the program is correct but I think it is. There should be a coffee-cup icon beside the Hello label when you open the root node.
