Question

我正在尝试在JavaFX中的TextFlow中显示文本。它没有显示任何内容，我不确定为什么这不起作用。我在我的视图中添加了一个TextFlowid，并尝试在控制器中添加一些文本。

控制器：

public class LoggingTabController
{

   @FXML
    private TextFlow tflow;
  @FXML
    public void initialize()
    {

        Text text1 = new Text("asd");
        Text text2 = new Text("Some Text");
        tflow.getChildren().addAll(text1, text2);
  }
}

查看：

<GridPane maxHeight="1.7976931348623157E308" maxWidth="1.7976931348623157E308" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1">

         </children>
      </HBox>
      <ScrollPane prefHeight="600.0" prefWidth="449.0">
        <content>
          <AnchorPane minHeight="0.0" minWidth="0.0" prefHeight="567.0" prefWidth="511.0">
               <children>
          <TextFlow id="tFlow" fx:id="tFlow" layoutX="-1.0" layoutY="1.0" prefHeight="567.0" prefWidth="511.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0" />
               </children></AnchorPane>
        </content>
      </ScrollPane>
   </children>
</GridPane>

为什么它没有显示任何内容？
