Question

我正在尝试在边框内布置表格。当我这样做时，缩小窗口会截断表格并且不显示滚动条。

这是布局：

<BorderPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="600.0" prefWidth="1000.0" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1" fx:controller="javafxapplication1.SimpleUIController">
<center>
<AnchorPane>
      <TableView fx:id="table" prefHeight="500.0" prefWidth="1000.0" AnchorPane.bottomAnchor="10.0" AnchorPane.leftAnchor="10.0" AnchorPane.rightAnchor="50.0" AnchorPane.topAnchor="10.0" BorderPane.alignment="CENTER">
        <columns>
          <TableColumn fx:id="colName" prefWidth="500.0" text="Name" />
          <TableColumn fx:id="colPrice" prefWidth="400.0" text="Price" />
        </columns>
      </TableView>
</AnchorPane>
</center>
</BorderPane>

这就是窗口比桌子小的样子：

如果我像这样删除边框窗格：

<AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="600.0" prefWidth="1000.0" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1" fx:controller="javafxapplication1.SimpleUIController">
      <TableView fx:id="table" prefHeight="500.0" prefWidth="1000.0" AnchorPane.bottomAnchor="10.0" AnchorPane.leftAnchor="10.0" AnchorPane.rightAnchor="50.0" AnchorPane.topAnchor="10.0">
        <columns>
          <TableColumn fx:id="colName" prefWidth="500.0" text="Name" />
          <TableColumn fx:id="colPrice" prefWidth="400.0" text="Price" />
        </columns>
      </TableView>
</AnchorPane>

然后我根据需要获得滚动条：

使用边框时如何获取滚动条？

尝试将ScrollPane设置为父节点，如下所示：

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

<?import javafx.scene.control.ScrollPane?>
<?import javafx.scene.control.TableColumn?>
<?import javafx.scene.control.TableView?>
<?import javafx.scene.layout.BorderPane?>
<?import javafx.scene.layout.HBox?>
<?import javafx.scene.layout.VBox?>


<HBox

    maxWidth="1.7976931348623157E308"

    xmlns:fx="http://javafx.com/fxml/1">
    <children>

            HBox.hgrow="ALWAYS">
            <children>
                <ScrollPane

                                            prefWidth="400.0"
                                            text="C1" />
                                        <TableColumn

                                            prefWidth="500.0"
                                            text="C2" />
                                    </columns>

                                        <TableView fx:constant="CONSTRAINED_RESIZE_POLICY" />

                </ScrollPane>
            </children>
        </VBox>
    </children>
</HBox>

在BorderPane中使用JFX No Scrollbar
