如何将JavaFX中的矩形或GridPane列表缩放到窗口宽度？

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.GridPane;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;

public class Main extends Application {

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

    @Override
    public void start(Stage primaryStage) {
        // 创建矩形
        Rectangle rectangle = new Rectangle(0, 0, 200, 100);
        rectangle.setFill(Color.BLUE);

        // 创建GridPane
        GridPane gridPane = new GridPane();
        gridPane.setPrefWidth(200); // 设置初始宽度
        gridPane.setStyle("-fx-background-color: lightgray;");

        // 添加矩形和GridPane到主要布局容器
        AnchorPane root = new AnchorPane(gridPane, rectangle);

        // 设置主要布局容器的宽度与窗口宽度一致
        root.setPrefWidth(primaryStage.getWidth());
        root.widthProperty().addListener((obs, oldVal, newVal) -> {
            gridPane.setPrefWidth((double) newVal);
        });

        // 创建场景并设置为舞台场景
        Scene scene = new Scene(root);
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}
