如何在javafx中将文本大小绑定到滑块？

Slider slider = new Slider();
Text text = new Text();

text.fontProperty().bind(Bindings.createObjectBinding(() ->
    Font.font(slider.getValue()), slider.valueProperty()));

slider.setMin(0);
slider.setMax(50);
slider.setValue(12);

import javafx.application.Application;
import javafx.beans.binding.Bindings;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Slider;
import javafx.scene.layout.VBox;
import javafx.scene.text.Font;
import javafx.scene.text.Text;
import javafx.stage.Stage;

public class TextSizeBindingExample extends Application {

    @Override
    public void start(Stage primaryStage) {
        Slider slider = new Slider();
        Text text = new Text();

        text.fontProperty().bind(Bindings.createObjectBinding(() ->
                Font.font(slider.getValue()), slider.valueProperty()));

        slider.setMin(0);
        slider.setMax(50);
        slider.setValue(12);

        VBox vbox = new VBox(10, slider, text);
        vbox.setPadding(new Insets(10));

        primaryStage.setScene(new Scene(vbox));
        primaryStage.setTitle("Text Size Binding Example");
        primaryStage.show();
    }

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