如何使 AnchorPane 随窗口调整大小？

Question

我正在使用 Scene Builder 来设计布局。 父节点是一个 AnchorPane，它包含一个应该随它调整大小的 GridPane。 然而，AnchorPane 停止使用 GridPane 调整大小（我认为）。 如何在用鼠标拖动窗口放大时调整其大小？

文件格式：

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Menu?>
<?import javafx.scene.control.MenuBar?>
<?import javafx.scene.control.MenuItem?>
<?import javafx.scene.control.ScrollPane?>
<?import javafx.scene.image.ImageView?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.ColumnConstraints?>
<?import javafx.scene.layout.GridPane?>
<?import javafx.scene.layout.RowConstraints?>
