是否禁用红色“X”按钮关闭整个JavaFX程序?w/ Java8？

import javafx.application.Application;
import javafx.stage.Stage;
import javafx.stage.WindowEvent;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {
        primaryStage.setOnCloseRequest((WindowEvent event) -> {
            event.consume(); // 取消关闭请求
        });

        // 其他初始化和界面构建代码...

        primaryStage.show();
    }

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