Javafx：SplitPane 调整子项大小

Question

我最喜欢一个 .fxml 文件，我在其中添加了一些 TitledPane 但我无法在应用程序中调整它们的大小。这是代码：

<ScrollPane AnchorPane.topAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.bottomAnchor="0.0"
            AnchorPane.leftAnchor="0.0">
    <SplitPane orientation="VERTICAL" fx:id="splitPane">
        <TitledPane>
            <TextArea fx:id="taTop" wrapText="true" editable="false" prefHeight="100"/>
        </TitledPane>
        <TitledPane>
            <TableView fx:id="tableFrist" minHeight="120" maxHeight="120">
                <columns>
                    <TableColumn fx:id="column" prefWidth="200"/>
                </columns>
            </TableView>
        </TitledPane>
        <TitledPane>
            <TreeTableView fx:id="tableSecond">
                <columns>
                    <TreeTableColumn fx:id="columnTreeS" prefWidth="200"/>
                </columns>
            </TreeTableView>
        </TitledPane>
        <TitledPane>
            <TreeTableView fx:id="tableThird">
                <columns>
                    <TreeTableColumn fx:id="columnTreeT" prefWidth="200"/>
                </columns>
            </TreeTableView>
        </TitledPane>
        <TitledPane>
            <TextArea fx:id="taBot" wrapText="true" editable="false"/>
        </TitledPane>
    </SplitPane>
</ScrollPane>

我错过了什么，或者为什么我无法调整窗格？

Answer 1

将 ScrollPane 的 fitToHeight 和 fitToWidth 属性设置为 true:

https://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/ScrollPane.html#fitToHeightProperty

If true and if the contained node is a Resizable, then the node will be kept resized to match the height of the ScrollPane's viewport. If the contained node is not a Resizable, this value is ignored.

改变

<ScrollPane AnchorPane.topAnchor="0.0" 
            AnchorPane.rightAnchor="0.0" 
            AnchorPane.bottomAnchor="0.0"
            AnchorPane.leftAnchor="0.0">

到

<ScrollPane AnchorPane.topAnchor="0.0" 
            AnchorPane.rightAnchor="0.0" 
            AnchorPane.bottomAnchor="0.0"
            AnchorPane.leftAnchor="0.0" 
            fitToHeight="true" 
            fitToWidth="true">
