可以使用手风琴(accordion)控件对标题窗格进行分组。

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Accordion;
import javafx.scene.control.Button;
import javafx.scene.control.TitledPane;
import javafx.stage.Stage;

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

    @Override
    public void start(Stage primaryStage) {
        Group g = new Group();
        Scene scene = new Scene(g, 550, 250);

        TitledPane t1 = new TitledPane("T1", new Button("B1"));
        TitledPane t2 = new TitledPane("T2", new Button("B2"));
        TitledPane t3 = new TitledPane("T3", new Button("B3"));
        Accordion accordion = new Accordion();
        accordion.getPanes().addAll(t1, t2, t3);
// from  ww W. y  I I ba  I . c  O  M
        g.getChildren().add(accordion);

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

上面的代码生成以下结果。

import javafx.scene.control.Accordion;
import javafx.scene.control.Button;

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

    @Override
    public void start(Stage primaryStage) {
        Group g = new Group();
        Scene scene = new Scene(g, 550, 250);

        TitledPane t1 = new TitledPane("T1", new Button("B1"));
        TitledPane t2 = new TitledPane("T2", new Button("B2"));
        TitledPane t3 = new TitledPane("T3", new Button("B3"));
        Accordion accordion = new Accordion();
        accordion.getPanes().addAll(t1, t2, t3);

        accordion.expandedPaneProperty()
                .addListener((ObservableValue<? extends TitledPane> ov, TitledPane old_val, TitledPane new_val) -> {
                    if (new_val != null) {
                        System.out.println(accordion.getExpandedPane().getText());
                    }
                });

        g.getChildren().add(accordion);
// copyright  wW W.YI I BA i.c O m 
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

当在手风琴中打开标题窗格时，手风琴的展开窗格属性会更改。
