JavaFX手风琴

JavaFX教程 – JavaFX手风琴

可以使用手风琴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;
//from   w  w w  .j  ava 2  s  .com
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);

    g.getChildren().add(accordion);

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

上面的代码生成以下结果。

import javafx.scene.Scene;
import javafx.scene.control.Accordion;
import javafx.scene.control.Button;
import javafx.scene.control.TitledPane;
import javafx.stage.Stage;
/*  w  w w  .  ja va  2 s  . c  o m*/
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);

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

当在手风琴中打开标题窗格时，手风琴的扩展窗格属性改变。
