Add a button to the right of tabpane [duplicate]

Question

I have a tabpane with some tabs. I want to add a single button on the same line as the tabs (should be right aligned and opposite to the tabs).

I was thinking I can add the Button like: (but this doesnt work)

tabPane.getTabs().add(tab1,tab2,tab3,new Button("btn"))

Please tell me how to do this (see example of image of what i want below).

NOTE: THE BUTTON SHOULD ONLY BE VISIBLE WHEN TAB1 OF THE TABAREA IS ACTIVE. THE BUTTON SHOULD BE HIDDEN WHEN ON TAB2 AND TAB3. THANKS

Using javafx.scene.layout.AnchorPane you can group your tabpages and button into same layout

Refer code below,

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Tab;
import javafx.scene.control.TabPane;
import javafx.scene.layout.AnchorPane;
import javafx.stage.Stage;

public class JavaFXTest6 extends Application {

    @Override
    public void start(Stage primaryStage) {
        final AnchorPane root = new AnchorPane();
        final TabPane tabs = new TabPane();
        final Button addButton = new Button("Btn1");
        addButton.setPrefWidth(41);
        addButton.setPrefHeight(15);

        AnchorPane.setTopAnchor(tabs, 5.0);
        AnchorPane.setLeftAnchor(tabs, 5.0);
        AnchorPane.setRightAnchor(tabs, 5.0);
        AnchorPane.setTopAnchor(addButton, 10.0);
        AnchorPane.setRightAnchor(addButton, 10.0);
        tabs.setStyle("-fx-padding: 2 0 0 50;");

        Tab tab = new Tab("Tab 1");
        Tab tab1 = new Tab("Tab 2");
        Tab tab2 = new Tab("Tab 3");

        tabs.getTabs().add(tab);
        tabs.getTabs().add(tab1);
        tabs.getTabs().add(tab2);

        root.getChildren().addAll(tabs, addButton);

        final Scene scene = new Scene(root, 300, 200);
        primaryStage.setTitle("Tabs with button !");
        primaryStage.setScene(scene);
        primaryStage.show();

    }

    public static void main(String[] args) {
        launch(args);
    }
}
