public class SampleApp extends Application {

  @Override
  public void start(Stage primaryStage) throws Exception {

    SearchableComboBox<String> searchableComboBox = new SearchableComboBox<>();
    // tooltip is not visible
    searchableComboBox.setTooltip(new Tooltip("Search an entry"));

    ComboBox<String> cb = new ComboBox<>();
    // tooltip is visible
    cb.setTooltip(new Tooltip("Select an entry"));

    Scene scene = new Scene(new VBox(searchableComboBox, cb), 300, 300);
    primaryStage.setScene(scene);
    primaryStage.show();
  }

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