Spring Hibernate Simple JavaFX TreeView example

JavaFX provide TreeView control, a view on to a tree root (of type TreeItem). By using a TreeView, it is possible to drill down into the children of a TreeItem, recursively until a TreeItem has no children (that is, it is a leaf node in the tree).

package javafxtest;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TreeItem;
import javafx.scene.control.TreeView;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

/**

 */
public class JavaFXtestUI extends Application {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        launch(args);
    }
    
    @Override
    public void start(Stage primaryStage) {
        
        TreeItem<String> treeItemRoot = new TreeItem<> ("Root");
        
        TreeItem<String> nodeItemA = new TreeItem<>("Item A");
        TreeItem<String> nodeItemB = new TreeItem<>("Item B");
        TreeItem<String> nodeItemC = new TreeItem<>("Item C");
        treeItemRoot.getChildren().addAll(nodeItemA, nodeItemB, nodeItemC);
        
        TreeItem<String> nodeItemA1 = new TreeItem<>("Item A1");
        TreeItem<String> nodeItemA2 = new TreeItem<>("Item A2");
        TreeItem<String> nodeItemA3 = new TreeItem<>("Item A3");
        nodeItemA.getChildren().addAll(nodeItemA1, nodeItemA2, nodeItemA3);
        
        TreeView<String> treeView = new TreeView<>(treeItemRoot);
        StackPane root = new StackPane();
        root.getChildren().add(treeView);
        
        Scene scene = new Scene(root, 300, 250);
        
        primaryStage.setTitle("java-buddy.blogspot.com");
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}
