JavaFx 2.x : Stage within a TabPane - javafx-2

Question

I need to display one or more stage(s) within a TabPane by clicking on a button, such as the picture below
My target is to have a situation similar to JInternalFrame in Swing: how to accomplish this?
I am not able to add stage as children to the tab pane.
If this is not possible, what could be other solutions? I would like to have SplitPanes on the stage.
Thanks
PS I am using Win7, NetBeans 7.4 Beta (Build 201307092200), SceneBuilder 1.1
Edit: here is how it looks after some VFXWindows css changes
There's one thing worth notice: I have had to add a node ( in my case an HBox with prefSize(0,0), otherwise I can't move o resize the first window plotted, only the first one.
As last, I can't find a way to set windows full screen (maximize).

Here I put an example of windows from jfxtras inside of Tabs, I just modify the example.
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.Tab;
import javafx.scene.control.TabPane;
import javafx.stage.Stage;
import jfxtras.labs.scene.control.window.CloseIcon;
import jfxtras.labs.scene.control.window.MinimizeIcon;
import jfxtras.labs.scene.control.window.Window;
public class WindowInTab extends Application {
private static int counter = 1;
private void init(Stage primaryStage) {
TabPane tabPane = new TabPane();
Tab tab = generateTab("Windows...");
Tab anotherTab = generateTab("More Windows");
tabPane.getTabs().addAll(tab, anotherTab);
primaryStage.setResizable(true);
primaryStage.setScene(new Scene(tabPane, 600, 500));
}
private Tab generateTab(String tabName) {
Tab tab = new Tab(tabName);
final Group root = new Group();
tab.setContent(root);
Button button = new Button("Add more windows");
root.getChildren().addAll(button);
button.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent arg0) {
// create a window with title "My Window"
Window w = new Window("My Window#"+counter);
// set the window position to 10,10 (coordinates inside canvas)
w.setLayoutX(10);
w.setLayoutY(10);
// define the initial window size
w.setPrefSize(300, 200);
// either to the left
w.getLeftIcons().add(new CloseIcon(w));
// .. or to the right
w.getRightIcons().add(new MinimizeIcon(w));
// add some content
w.getContentPane().getChildren().add(new Label("Content... \nof the window#"+counter++));
// add the window to the canvas
root.getChildren().add(w);
}
});
return tab;
}
public double getSampleWidth() {return 600;}
public double getSampleHeight() {return 500;}
#Override
public void start(Stage primaryStage) throws Exception {
init(primaryStage);
primaryStage.show();
}
public static void main(String[] args) {launch(args);}
}
I don't know if this was exactly what you were looking for. Hope it helps!
