Javafx scrollbars position - javafx

Question

I have a TextArea inside of a ScrollPane. I have set the TextArea nodeOrientation="RIGHT_TO_LEFT". When I do this the scrollbars go on the left side of the window instead of the right side, which I assume is default. How do I force the scrollbars to the right side of the window?
I have tried setting the nodeOrientation of my AnchorPane and ScrollPane to left to right but that did not help
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.ScrollPane?>
<?import javafx.scene.control.TextArea?>
<?import javafx.scene.layout.AnchorPane?>
<AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="200.0" prefWidth="400.0" xmlns="http://javafx.com/javafx/11.0.1" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.mycompany.mycalc.MyCalcHistoryController">
<children>
<ScrollPane fx:id="scrollPane" fitToHeight="true" fitToWidth="true" prefHeight="242.0" prefWidth="400.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
<content>
<TextArea fx:id="txtHistory" editable="false" nodeOrientation="RIGHT_TO_LEFT" />
</content>
</ScrollPane>
</children>
</AnchorPane>

I used BorderPane instead of AnchorPane and did not use a fxml file. Here is my code and after the code is a screen capture. As you can see, setting the node orientation for the TextArea only does not alter the location of the scroll bar on the ScrollPane.
import javafx.application.Application;
import javafx.geometry.NodeOrientation;
import javafx.scene.Scene;
import javafx.scene.control.ScrollPane;
import javafx.scene.control.TextArea;
import javafx.scene.control.ScrollPane.ScrollBarPolicy;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class FxTest00 extends Application {
#Override
public void start(Stage stage) throws Exception {
TextArea txtAr = new TextArea("myxomatosis");
txtAr.setNodeOrientation(NodeOrientation.RIGHT_TO_LEFT);
ScrollPane scrollPane = new ScrollPane(txtAr);
scrollPane.setVbarPolicy(ScrollBarPolicy.ALWAYS);
BorderPane root = new BorderPane();
root.setCenter(scrollPane);
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
EDIT (after Ray_White's initial comment to my answer)
The scrollbar you are referring to (in your comment) is part of TextArea and not related to the ScrollPane parent. In the below code, the TextArea is added directly to the BorderPane, i.e. the below code contains no ScrollPane.
The way I found to remove the TextArea vertical scrollbar is via the TextArea style. I created a CSS file named scrolbar.css. Here is its contents:
.text-area .scroll-pane {
-fx-vbar-policy: never;
}
And here is the modified code, including your suggestion to add text to the TextArea to force scrolling.
import javafx.application.Application;
import javafx.geometry.NodeOrientation;
import javafx.scene.Scene;
import javafx.scene.control.TextArea;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class FxTest00 extends Application {
#Override
public void start(Stage stage) throws Exception {
TextArea txtAr = new TextArea("myxomatosis");
txtAr.appendText("\n");
txtAr.appendText("One");
txtAr.appendText("\n");
txtAr.appendText("Two");
txtAr.appendText("\n");
txtAr.appendText("Three");
txtAr.appendText("\n");
txtAr.appendText("Four");
txtAr.appendText("\n");
txtAr.appendText("Five");
txtAr.appendText("\n");
txtAr.appendText("Six");
txtAr.appendText("\n");
txtAr.appendText("Seven");
txtAr.appendText("\n");
txtAr.appendText("Eight");
txtAr.appendText("\n");
txtAr.appendText("Nine");
txtAr.appendText("\n");
txtAr.appendText("Ten");
txtAr.appendText("\n");
txtAr.appendText("Eleven");
txtAr.setNodeOrientation(NodeOrientation.RIGHT_TO_LEFT);
BorderPane root = new BorderPane();
root.setCenter(txtAr);
Scene scene = new Scene(root);
scene.getStylesheets().add(getClass().getResource("scrolbar.css").toString());
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
And here is the screen capture of the modified GUI. As you can see, no scrollbar.
