Question

我正在尝试将根菜单设置为顶部＆amp;然后在下面做一个分屏。

我在网上找到了一个网站“http://code.makery.ch/library/javafx-8-tutorial/part1/”。它有我想要做的例子。我想用真实的代码进行硬编码，而不是像他那样使用拖放的东西。

到目前为止，我能够编写程序＆amp;通过root＆amp; amp;显示菜单运行一切，但我无法弄清楚如何在它下面添加“分屏”而不会引起问题。

每当我尝试在root中添加分屏实现和菜单时，它都不起作用。

我可以在JFrame中完成，但我想在JavaFX root中完成它。

我在网上找不到任何关于它的信息，严重的是被困了4个小时。

（项目名称为“WorkAir”）这是我目前的代码：

package application;

        primaryStage.setTitle("WorkAir");

        Scene scene = new Scene(root, 1000, 550, Color.WHITE);

        MenuBar menuBar = new MenuBar();
        menuBar.prefWidthProperty().bind(primaryStage.widthProperty());
        root.setTop(menuBar);

        primaryStage.setOnCloseRequest(new EventHandler<WindowEvent>() {
            @Override

        //File Menu Trees

        exitMenuItem.setOnAction(new EventHandler<ActionEvent>() {

                //File Menu Trees Exit
                Label secondLabel = new Label("Are you sure you want to exit?");
                Button buttonNo = new Button();

                buttonNo.setStyle("-fx-font: 10 arial; -fx-base: #d3d3d3;");

                buttonYes.setTranslateY(30);

                buttonNo.setText("Exit, No");
                buttonNo.setOnAction(new EventHandler<ActionEvent>() {

                        Stage secondStage = (Stage) buttonNo.getScene().getWindow();
                        secondStage.close();
                    }

                });

                buttonYes.setText("Exit, Yes");
                buttonYes.setOnAction(new EventHandler<ActionEvent>() {
                    @Override

                        System.out.println("Yes");
                        Platform.exit();
                    }

                });

                StackPane secondaryLayout = new StackPane();
                secondaryLayout.getChildren().add(secondLabel);
                secondaryLayout.getChildren().add(buttonNo);
                secondaryLayout.getChildren().add(buttonYes);

                Scene secondScene = new Scene(secondaryLayout, 350, 150);

                Stage secondStage = new Stage();
                secondStage.setTitle("Exit");
                secondStage.setScene(secondScene);

                //Set position of second window, related to primary window.
                secondStage.setX(primaryStage.getX() + 250);
                secondStage.setY(primaryStage.getY() + 100);
                secondStage.centerOnScreen();

                secondStage.show();
            }
        });

        //2nd Menu
        Menu secondMenu = new Menu("2nd");
        CheckMenuItem htmlMenuItem = new CheckMenuItem("HTML");
        htmlMenuItem.setSelected(true);
        secondMenu.getItems().add(htmlMenuItem);

        CheckMenuItem cssMenuItem = new CheckMenuItem("CSS");
        cssMenuItem.setSelected(true);

        //3rd Menu

        ToggleGroup tGroup = new ToggleGroup();

        Menu Menu = new Menu("Sub Menu");
        Menu.getItems().addAll(

        //Menu Bar Get All
        menuBar.getMenus().addAll(fileMenu, secondMenu, thirdMenu);

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

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

为此目的使用SplitPane。

这是一个简短的例子。当然，在实际代码中，您将保留对某些变量中需要访问的Node的引用：

@Override
public void start(Stage primaryStage) {
    SplitPane splitPane = new SplitPane(new TableView(),
                                        new VBox(new Label("some other content")));

    splitPane.setOrientation(Orientation.HORIZONTAL);

    // place splitPane as center
    BorderPane borderPane = new BorderPane(splitPane);

    borderPane.setTop(new MenuBar(new Menu("File")));

    Scene scene = new Scene(borderPane, 600, 400);

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