How to create dialog in JavaFX

Question

I tested to create simple dialog in JavaFX but for some reason the code is not working:

MenuBar menuBar = new MenuBar();

        // File menu - new, save, exit
        Menu menu = new Menu("File");
        menu.getItems().add(new MenuItem("New"));
        menu.getItems().add(new MenuItem("Save"));
        menu.getItems().add(new SeparatorMenuItem());

        menuBar.getMenus().add(menu);

        // Options menu - Preferences
        Menu options = new Menu("Options");
        options.getItems().add(new MenuItem("Preferences"));

        menuBar.getMenus().add(options);

        // Help menu - About
        Menu help = new Menu("Help");
        MenuItem about = new MenuItem("Exit");


        about.setOnAction(new EventHandler<ActionEvent>() {
            @Override
            public void handle(ActionEvent e) {
                Stage dialogStage = new Stage();
                dialogStage.initModality(Modality.WINDOW_MODAL);
                dialogStage.setScene(new Scene(VBoxBuilder.create().
                        children(new Text("Hi"), new Button("Ok.")).
                        alignment(Pos.CENTER).padding(new Insets(5)).build()));
                dialogStage.show();
            }
        });

        menuBar.getMenus().add(help);

        menuBar.prefWidthProperty().bind(primaryStage.widthProperty());

        root.getChildren().add(menuBar);
        primaryStage.setScene(scene);
        primaryStage.show();

I want when I click on About menu item to display simple dialog window with author information. Can you tell me how to correct my mistake, please?

Do you see the About menu item? In the shown code it's not added to a menu... — Puce, Apr 18 '13 at 11:15

I use http://sourceforge.jp/projects/jfxmessagebox/wiki/JfxMessageBox for my Messageboxes. I hope this helps.

You can try my custom Dialog. Visit FXDialog public repository.

I was also looking for FX dialog features for a few days. Before I attempt to write my own complicated dialog, I came across the"savior" ControlsFX [here] (http://fxexperience.com/). It works like a miracle to me. However, You will have to upgrade to JDK8 fully experience the wonder of ControlFX has on FX8. I believe everyone will use JDK8 sooner or later.

It's lucky my original code did not get too far before it becomes too complicated for me to make such transition. :)

Hope this post also feeds 5-thousand JAVAer. Check out how it works with the following sample code:

    Action response = Dialogs.create()
        .owner( null)
        .title("Confirmation")
        .masthead("Are you sure to delete UserLevel: '"+ul.getLevelname()+"' ?")
        .message(entry)
        .showConfirm();

    System.out.println("response: " + response);        


    if (response.toString().equals("YES")){
        if(!Main.db.em.getTransaction().isActive())
            Main.db.em.getTransaction().begin();

        Main.db.em.remove(ul);
        Main.db.em.getTransaction().commit();
        tbvMain.getItems().remove(tbvMain.getSelectionModel().getSelectedIndex());
    }
