我正在学习 JavaFx 并构建一个示例应用程序，该应用程序将以可滚动的方式显示餐厅菜单项列表。我发现最好的方法是使用controlsfx 中的GridView 控件，因为即使有大量菜单项，滚动也会很快。这是我试图使其工作的示例代码：

public class Main extends Application {
    @Override
    public void start(Stage primaryStage) {
        try {
            VBox root = new VBox();
            Scene scene = new Scene(root,400,400);
            scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
            primaryStage.setScene(scene);

            ObservableList<GridPane> list = FXCollections.<GridPane>observableArrayList();
            GridView<GridPane> gridView = new GridView<>(list);

            gridView.setCellFactory(new Callback<GridView<GridPane>, GridCell<GridPane>>() {
                 public GridCell<GridPane> call(GridView<GridPane> gridView) {
                     return new GridCell<GridPane>();
                 }
             });

            Label lblName1 = new Label("Name");
            GridPane grid = new GridPane();
            grid.addRow(0, lblName1);

            Label lblName2 = new Label("Price");
            grid.addRow(1, lblName2);

            list.add(grid);

            root.getChildren().add(gridView);
            primaryStage.show();
        } catch(Exception e) { …
