JavaFX如何隐藏＆＃39;标题为扩展后的回归

Question

我有TitledPane，我想在按下按钮后隐藏（扩展后 - 取消展开）。有什么办法吗？我没有找到任何办法:(谢谢！

Answer 1

只做

titledPane.setExpanded(false);

完整示例：

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TitledPane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class TitledPaneExample extends Application {

    @Override
    public void start(Stage primaryStage) {
        Label label = new Label("Some content");
        Button button = new Button("OK");
        VBox content = new VBox(10, label, button);
        TitledPane titledPane = new TitledPane("Titled Pane", content);
        button.setOnAction(e -> titledPane.setExpanded(false));
        VBox root = new VBox(titledPane);
        Scene scene = new Scene(root, 250, 400);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

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