如何在JavaFX中扩展TextField的高度

import javafx.scene.control.TextField;

public class ExtendedTextField extends TextField {

    public ExtendedTextField() {
        super();
    }

    @Override
    protected double computePrefHeight(double width) {
        return super.computePrefHeight(width) * 2; // 设置高度为原始高度的两倍
    }
}

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {
        ExtendedTextField extendedTextField = new ExtendedTextField();

        VBox root = new VBox();
        root.getChildren().add(extendedTextField);

        Scene scene = new Scene(root, 200, 200);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

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