当我有复选框检查如何从表视图中删除行？

Question

我有以下项目：

@FXML 
private Button bttnRemove; 
@FXML 
private TableView<EventsBean> eventsTable; 
@FXML 
private TableColumn<EventsBean, String> eventCol; 
@FXML 
private TableColumn<EventsBean, LocalDate> dateCol; 
@FXML 
private TableColumn<EventsBean, Boolean> doneCol; 
@FXML 
private TableColumn<EventsBean, String> observationCol; 
@FXML 
private TableColumn<EventsBean, Boolean> removeCol; 

和removeCol创建复选框：

ObservableList<EventsBean> dataList = FXCollections.observableArrayList(); 

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

     removeCol.setCellFactory(CheckBoxTableCell.forTableColumn(removeCol)); 
     removeCol.setCellValueFactory(new PropertyValueFactory<EventsBean, Boolean>("remove")); 
     eventsTable.setItems(dataList); 

     bttnAddEvent.setOnAction((ActionEvent e) -> { 
     text = eventsSelector.getValue().toString(); 
     dataList.add(new EventsBean(text, isoDate, "")); 
    }); 

     bttnRemove.setOnAction((ActionEvent e) -> { 
     //code here... 
    }); 
} 

我想用bttnRemove删除行具有复选框从removeCol检查。

我发现，工作非常好下一个解决方案：

public class EventsBean { 


private SimpleStringProperty event; 
private SimpleObjectProperty<LocalDate> date; 
private SimpleStringProperty observation; 
private SimpleBooleanProperty selected; 

public EventsBean(String event, LocalDate date, String observation, boolean selected) { 
    this.event = new SimpleStringProperty(event); 
    this.date = new SimpleObjectProperty<LocalDate>(date); 
    this.observation = new SimpleStringProperty(observation); 
    this.selected = new SimpleBooleanProperty(selected); 
} 

// the other getters and setters 

public boolean getSelected(){ 
    return selectedProperty().get(); 
} 

public SimpleBooleanProperty selectedProperty() { 
    return this.selected; 
} 
} 

在我的控制器类的初始化方法：

removeCol.setCellValueFactory(cellData -> cellData.getValue().selectedProperty()); 

bttnRemove.setOnAction((ActionEvent e) -> { 
     ObservableList<EventsBean> dataListToRemove = FXCollections.observableArrayList(); 
     for (EventsBean bean : dataList) { 
      if (bean.getSelected()) { 
       dataListToRemove.add(bean); 
      } 
     } 
     dataList.removeAll(dataListToRemove);
