javafx gridpane 布局与换行文本

Question

我正在使用 JavaFX 8。尝试使用 GridPage 来显示一组属性和值。有些值可能太长，无法放在一行中。我想包装这些值，但似乎无法弄清楚如何使网格 Pane 垂直扩展以容纳包装的文本。我基本上想要像您在 HTML 表中看到的行为。不确定我应该使用 JavaFX 中是否有不同的布局。

Property A    Value A
Property B    Value B
Property C    The Values for property C is so long
              that it wraps
Property D    Value D

感谢任何帮助

使用 SceneBuilder 构建:

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

<?import javafx.geometry.*?>
<?import javafx.scene.control.*?>
<?import java.lang.*?>
<?import javafx.scene.layout.*?>

<VBox prefWidth="220.0" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1">
   <children>
      <GridPane hgap="20.0" vgap="10.0">
        <columnConstraints>
          <ColumnConstraints hgrow="SOMETIMES" maxWidth="-Infinity" minWidth="-Infinity" />
          <ColumnConstraints hgrow="SOMETIMES" maxWidth="1.7976931348623157E308" minWidth="20.0" />
        </columnConstraints>
        <rowConstraints>
          <RowConstraints minHeight="-Infinity" valignment="TOP" vgrow="SOMETIMES" />
          <RowConstraints minHeight="-Infinity" valignment="TOP" vgrow="SOMETIMES" />
          <RowConstraints minHeight="-Infinity" valignment="TOP" vgrow="SOMETIMES" />
        </rowConstraints>
         <children>
            <Label text="Property A" />
            <Label text="Property B" GridPane.rowIndex="1" />
            <Label text="Property C" GridPane.rowIndex="2" />
            <Label text="Value A" GridPane.columnIndex="1" />
            <Label text="The value for property B is so long that it wraps" wrapText="true" GridPane.columnIndex="1" GridPane.rowIndex="1" />
            <Label text="Value C" GridPane.columnIndex="1" GridPane.rowIndex="2" />
         </children>
         <padding>
            <Insets bottom="10.0" left="10.0" right="10.0" top="10.0" />
         </padding>
      </GridPane>
   </children>
</VBox>
