小编Tol*_*mer的帖子

我试图在javafx中选择多行,但我不想使用键盘(SHIFT).应该在我点击它之后选择,当我点击其他列时它也应该被选中.

我在这里检查了一些其他的答案,但我找不到简短而方便的东西.有更短的方法吗？

@FXML 

private static Logger logger = Logger.getLogger(MainFrameControl.class);


public TableView<Box> boxTable;
protected final ObservableList<Box> boxData = FXCollections.observableArrayList();

Service service = new ServiceImpl();
private Stage mainStage;

public MainFrameControl(Stage mainStage) {



    FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("MainFrame.fxml"));
    fxmlLoader.setRoot(this);
    fxmlLoader.setController(this);
    this.mainStage = mainStage;


    Stage stage = new Stage();



    try {
        fxmlLoader.load();  

    } catch (IOException exception) {
        throw new RuntimeException(exception);
    }


    ArrayList<Box> list = service.findAllBoxen();

    TableColumn<Box, String> boxnameColumn = (TableColumn<Box, String>) boxTable.getColumns().get(0);
    boxnameColumn.setCellValueFactory(new PropertyValueFactory<Box, String>("boxName"));


    TableColumn<Box, String> sizeColumn = (TableColumn<Box, String>) boxTable.getColumns().get(1);
    sizeColumn.setCellValueFactory(new PropertyValueFactory<Box, …

我收到错误“无法从...找到模块'@babel/plugin-transform-runtime'”。我已经尝试了互联网上的所有解决方案，但没有真正有效。我该如何解决？任何建议将大大appriciated。

我有日期选择器的简单代码，它禁用所选日期之前的所有日期，但我也需要能够禁用其他日期（例如：17.10.2014 到 19.10.2014）。我怎样才能以禁用特定日期的方式更改它？

public class DatePickerSample extends Application {

private Stage stage;
private DatePicker checkInDatePicker;
private DatePicker checkOutDatePicker;

public static void main(String[] args) {
    Locale.setDefault(Locale.US);                  
    launch(args);
}

@Override
public void start(Stage stage) {
    this.stage = stage;
    stage.setTitle("DatePickerSample ");
    initUI();
    stage.show();
}

private void initUI() {
    VBox vbox = new VBox(20);
    vbox.setStyle("-fx-padding: 10;");
    Scene scene = new Scene(vbox, 400, 400);
    stage.setScene(scene);
    checkInDatePicker = new DatePicker();
    checkOutDatePicker = new DatePicker();
    checkInDatePicker.setValue(LocalDate.now());
    final Callback<DatePicker, DateCell> dayCellFactory = 
        new Callback<DatePicker, DateCell>() {
            @Override

我无法理解方法.我有方法需要填写,但我真的不明白第一个.Iterable如何成为返回类型以及它是如何使用的？一个例子很棒......

@Override
public Iterable<ClientInterface> getNeighbours() {

    return null;
}

@Override
public void addNeighbour(ClientInterface newNeighbour){
    //TODO Implement me!
}

@Override
public void removeNeighbour(String clientID) {
    //TODO Implement me!
}
