Question

我面临一个奇怪的问题。我正在使用最新的Gluon SceneBuilder for JavaFX。

在我的场景中，我有一个包含11列的Tableview。所有Colums都在Scene Builder中可见，但是一旦我运行Application，就没有可见的列。只有一个空白栏，给定的列名应该是。是的，我在保存SceneBuilder FXML文件后做了刷新。

包含Controller和fx的场景构建器设置：TableColumns和TableView的id是正确的。我错过了什么？

数据模型：

public class ArrivalsController implements Initializable{

    final ObservableList<ArrivalRecord> data = FXCollections.observableArrayList();


    @FXML   TableView<ArrivalRecord> arvtable;
    @FXML   TableColumn<ArrivalRecord, String> bookingId;
    @FXML   TableColumn<ArrivalRecord, String> firstName;
    @FXML   TableColumn<ArrivalRecord, String> lastName;
    @FXML   TableColumn<ArrivalRecord, String> arrival;
    @FXML   TableColumn<ArrivalRecord, String> checkout;
    @FXML   TableColumn<ArrivalRecord, String> roomNumber;
    @FXML   TableColumn<ArrivalRecord, String> roomType;
    @FXML   TableColumn<ArrivalRecord, String> nights;
    @FXML   TableColumn<ArrivalRecord, String> breakfast;
    @FXML   TableColumn<ArrivalRecord, String> amount;
    @FXML   TableColumn<ArrivalRecord, String> comment;




    @Override
    public void initialize(URL location, ResourceBundle resources) {

        bookingId.setCellValueFactory(cellData -> cellData.getValue().getBidProperty());
        firstName.setCellValueFactory(cellData -> cellData.getValue().getFirstNameProperty());
        lastName.setCellValueFactory(cellData -> cellData.getValue().getLastNameProperty());
        arrival.setCellValueFactory(cellData -> cellData.getValue().getArrivalProperty());
        checkout.setCellValueFactory(cellData -> cellData.getValue().getCheckoutProperty());
        roomNumber.setCellValueFactory(cellData -> cellData.getValue().getRoomNumberProperty());
        roomType.setCellValueFactory(cellData -> cellData.getValue().getRoomTypeProperty());
        nights.setCellValueFactory(cellData -> cellData.getValue().getNightsProperty());
        breakfast.setCellValueFactory(cellData -> cellData.getValue().getBreakfastProperty());
        amount.setCellValueFactory(cellData -> cellData.getValue().getAmountProperty());
        comment.setCellValueFactory(cellData -> cellData.getValue().getCommentProperty());

    }

TableColumns在TableView中不可见，但在Scene Builder中可见
