    @Override

        GridPane gp = new GridPane();
        gp.add(createNode("Stack"), 0, 0);
        gp.add(createNode("Over"),0,1);
        gp.add(createNode("Flow"), 0, 2);
        StackPane root = new StackPane();
        root.getChildren().add(gp);

        Scene scene = new Scene(root, 300, 250);

        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }

    public HBox createNode(String label) {
        HBox box = new HBox(20);
        final Label l = new Label(label);
        TextField field = new TextField();
        field.textProperty().addListener(new ChangeListener<String>() {
            @Override
            public void changed(ObservableValue<? extends String> ov, String t, String t1) {
                System.out.println( l.getText()+ " : " +t);
            }
        });
        box.getChildren().addAll(l,field);
        return box;

    }

}
