JavaFX 网格在调整其所属的行/列大小时不会调整大小

Question

我正在编写 JavaFX 程序（版本 17）。 我有一个主视图，它的基本节点是一个 GridPane。在运行时，我在第 1 列 - 第 0 行的主视图内添加了另一个 GridPane，但是当父网格变大时（当我在运行时修改窗口的大小时），这个子网格没有调整大小。这是主视图：

<GridPane fx:id="mainGrid" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="800.0" prefWidth="1300.0" stylesheets="@../atlantafx_css/nord-dark.css" xmlns="http://javafx.com/javafx/19" xmlns:fx="http://javafx.com/fxml/1" fx:controller="MainView.MainView">
  <columnConstraints>
    <ColumnConstraints hgrow="ALWAYS" maxWidth="100.0" minWidth="0.0" prefWidth="100.0" />
      <ColumnConstraints halignment="CENTER" hgrow="ALWAYS" minWidth="10.0" />
  </columnConstraints>
  <rowConstraints>
    <RowConstraints minHeight="10.0" prefHeight="30.0" valignment="CENTER" vgrow="ALWAYS" />
  </rowConstraints>
   <children>
      ...
   </children>
</GridPane>

和子网格：

<GridPane alignment="CENTER" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" stylesheets="@../atlantafx_css/nord-dark.css" xmlns="http://javafx.com/javafx/19" xmlns:fx="http://javafx.com/fxml/1" fx:controller="PCAView.PCAView">
  <columnConstraints>
      <ColumnConstraints halignment="CENTER" hgrow="ALWAYS" maxWidth="400.0" minWidth="400.0" />
    <ColumnConstraints halignment="CENTER" hgrow="ALWAYS" />
  </columnConstraints>
  <rowConstraints>
    <RowConstraints minHeight="10.0" prefHeight="269.0" vgrow="ALWAYS" />
    <RowConstraints minHeight="10.0" prefHeight="331.0" valignment="CENTER" vgrow="ALWAYS" />
  </rowConstraints>
   <children>
     ...
   </children>
</GridPane>

目的是将子网格添加到主网格的代码：

GridPane parentNode = ... // retrieving the view with FXMLLoader
mainGrid.add(parentNode, 1, 0);
mainGrid.layout();

我该怎么办？
