Java 调整网格窗格的大小'；s节点

我对以下代码有两个问题，我花了很长时间试图解决，但最终没有解决：

1-如下图所示，锚网不符合我使用SceneBuilder为其定义的高度属性，它应该完全适合gridpane的第2列并跨越3行，但是，它开始从gridpane顶部伸出：

第二个也是最重要的问题是，尽管我在FXML中显式定义了列和行约束，并分别启用了VGrow和HGrow，但当我最大化窗口时，GridPane根本不会缩放。但是，我想让它填满屏幕

为了防止

锚烷

溢出

网格窗格中的区域

，不要明确设置行的首选高度；让他们调整自己的大小以容纳内容（默认行为）

调整窗口大小时，

GridPane

没有调整大小的原因是它被包装在一个

窗格中（实际上不执行布局）。您可以省略包装器窗格，并将
GridPane
作为FXML的根吗？如果没有，请使用一种布局，使
GridPane
增长以适应整个内容（例如，使用
BorderPane
作为包装，并将
GridPane
放在中间：这里有许多其他选项）

SSCCE：



调整大小后：
您是否可以发布足够的代码来真实再现问题？在屏幕截图中，您的
GridPane
中似乎有一个
ListView
，它不在FXML文件中。如果你让你的问题变得独立和完整，人们也会更容易回答你的问题；没有人希望遍历FXML并添加所有必要的导入，您可以删除对控制器及其方法的引用。
