Question

Is it possible to define the TabBar to place the tabs at bottom instead of top?

Answer 1

Don’t define the TabBar! Use a proper layout pane e.g. javafx.scene.layout.BorderPane.
Find attached examples for JavaFX 2.0 API and FXML:

JAVAFX 2.0 API

package tabtest;

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

public class TabTest extends Application {

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

    @Override
    public void start(Stage primaryStage) {
        BorderPane root = new BorderPane();
        Scene scene = new Scene(root, 300, 250);

        TabPane tabPane = new TabPane();
        Tab tab1 = new Tab("Tab 1");
        tabPane.getTabs().add(tab1);

        root.setBottom(tabPane);

        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

FXML

package fxmltest;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class FxmlTest extends Application {

    public static void main(String[] args) {
        Application.launch(FxmlTest.class, args);
    }

    @Override
    public void start(Stage stage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("Sample.fxml"));

        Scene scene = new Scene(root, 300, 250);
        stage.setScene(scene);
        stage.show();
    }
}

Sample.fxml:

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

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

<BorderPane>
    <bottom>
        <TabPane>
            <tabs>
                <Tab text="Tab 1" />
            </tabs>
        </TabPane>
    </bottom>
</BorderPane>
