How to update an area of a scene

Question

Hi, I have an issue.
I'd like to know how to update an area of a stage, for example the right area of a split pane when I capture an event (a button pressing)
Thanks.

Now you have no issue :-)
For a SplitPane, just change the elements in the SplitPane's item list when the button's action event handler is invoked.
import javafx.application.Application;
import javafx.event.*;
import javafx.scene.Scene;
import javafx.scene.control.*;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
import java.util.Random;
public class SplitPaneSample extends Application {
  final Label[] prizes = { new Label("cake"), new Label("coal"), new Label("jelly"), new Label("doughnuts"), new Label("puppy") };
  final Random random = new Random(42);
  public static void main(String[] args) throws Exception { launch(args); }
  @Override public void start(final Stage stage) throws Exception {
    final SplitPane splitPane = new SplitPane();
    final Button pressMe = new Button("Pick a Prize");
    splitPane.getItems().addAll(pressMe, new Label(""));
    pressMe.setOnAction(new EventHandler<ActionEvent>() {
      @Override public void handle(ActionEvent actionEvent) {
        Label prize; do { prize = prizes[random.nextInt(prizes.length)]; } while (prize == splitPane.getItems().get(1));
        splitPane.getItems().set(1, prize);
    StackPane layout = new StackPane();
    layout.getChildren().add(splitPane);
    stage.setScene(new Scene(layout, 180, 80));
    stage.show();

Made code more concise, following Shakir's 2 cents.
