我想在我的应用程序中添加长文本。当我单击 POKAŻ 按钮时，它会向我显示来自名为 Dream 的类的梦想字段（字符串）。在这里我有一个问题。我的梦的内容很长，没有完全展现出来。当我将它包装在 ScrollPane 中时，它只显示一行文本。

这是我的应用程序的打印屏幕。

在此处输入图像描述

我可能会在单击 POKAŻ 按钮后添加它会更改 .fxml 文件

        public void showMeMyDream(ActionEvent e) throws IOException
    {
 showSelectedDream();
contentID.getChildren().clear();  contentID.getChildren().add(FXMLLoader.load(getClass().getResource("/fxml/showDreamFXML.fxml")));

    }

这是showDreamFXML.fxml的代码

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.geometry.*?>
<?import javafx.scene.text.*?>
<?import javafx.scene.control.*?>
<?import java.lang.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.layout.VBox?>
