我想在调整窗口大小以查看所有矩形时自动显示滚动条

调整大小之前：
在调整大小之前

调整大小后：
调整大小后

在底部，矩形消失了，但它们仍然存在。那么有没有办法将 Flowpane 与 Scrollpane 结合起来？

我正在使用 SceneBuilder，这是 fxml 代码：

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.layout.FlowPane?>
<?import javafx.scene.shape.Rectangle?>


<FlowPane alignment="TOP_CENTER" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1">
   <children>
      <Rectangle arcHeight="5.0" arcWidth="5.0" fill="DODGERBLUE" height="200.0" stroke="BLACK" strokeType="INSIDE" width="200.0" />
      <Rectangle arcHeight="5.0" arcWidth="5.0" fill="DODGERBLUE" height="200.0" stroke="BLACK" strokeType="INSIDE" width="200.0" />
      <Rectangle arcHeight="5.0" arcWidth="5.0" fill="DODGERBLUE" height="200.0" stroke="BLACK" strokeType="INSIDE" width="200.0" />
      <Rectangle arcHeight="5.0" arcWidth="5.0" fill="DODGERBLUE" height="200.0" stroke="BLACK" strokeType="INSIDE" width="200.0" />
      <Rectangle arcHeight="5.0" arcWidth="5.0" fill="DODGERBLUE" height="200.0" stroke="BLACK" strokeType="INSIDE" width="200.0" />
      <Rectangle arcHeight="5.0" arcWidth="5.0" fill="DODGERBLUE" height="200.0" stroke="BLACK" strokeType="INSIDE" width="200.0" />
   </children>
</FlowPane>

是的，有：只需使用FlowPaneas contentScrollPane和 usefitToWidth来ScrollPane根据可用宽度设置内容的宽度...

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.control.ScrollPane?>
<?import javafx.scene.layout.FlowPane?>
<?import javafx.scene.shape.Rectangle?>

<!-- make ScrollPane resize the content width -->
<ScrollPane fitToWidth="true" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8.0.60" xmlns:fx="http://javafx.com/fxml/1">
   <content>
      <!-- do not put bounds on the FlowPane size -->
      <FlowPane alignment="TOP_CENTER" maxHeight="-Infinity" maxWidth="Infinity" minHeight="-Infinity" prefWidth="600.0">
         <children>
            <Rectangle arcHeight="5.0" arcWidth="5.0" fill="DODGERBLUE" height="200.0" stroke="BLACK" strokeType="INSIDE" width="200.0" />
            <Rectangle arcHeight="5.0" arcWidth="5.0" fill="DODGERBLUE" height="200.0" stroke="BLACK" strokeType="INSIDE" width="200.0" />
            <Rectangle arcHeight="5.0" arcWidth="5.0" fill="DODGERBLUE" height="200.0" stroke="BLACK" strokeType="INSIDE" width="200.0" />
            <Rectangle arcHeight="5.0" arcWidth="5.0" fill="DODGERBLUE" height="200.0" stroke="BLACK" strokeType="INSIDE" width="200.0" />
            <Rectangle arcHeight="5.0" arcWidth="5.0" fill="DODGERBLUE" height="200.0" stroke="BLACK" strokeType="INSIDE" width="200.0" />
            <Rectangle arcHeight="5.0" arcWidth="5.0" fill="DODGERBLUE" height="200.0" stroke="BLACK" strokeType="INSIDE" width="200.0" />
         </children>
      </FlowPane>
   </content>
</ScrollPane>
