JavaFX，如果有人检查桌面视图中的复选框，我该如何触发事件

Question

我在JavaFX中遇到了一个大问题。我创建了一个TableView，并向TableView添加了一些CheckBox。如果有人检查TableView中的复选框，我想触发一个事件。我尝试了一些不同的方法，但我总是遇到同样的问题。在显示GUI之前，我启动程序并且“CheckBox触发器事件”运行五次。之后，我可以点击复选框，但没有任何发生。这是我的代码，我希望你能帮助我。谢谢！

添加听众项目的checkedProperty() S：

@FXML 
public void initalize() throws IOException 
    { 

    TableColumn<TrafficVolume, String> TVIDs = new TableColumn<TrafficVolume, String>("TV-ID"); 
    TableColumn<TrafficVolume, String> FLVL = new TableColumn<TrafficVolume, String>("Flight Level"); 
    TableColumn<TrafficVolume, Boolean> checkedCol = new TableColumn<TrafficVolume, Boolean>("Active"); 
    TABLETVID.setItems(list); 

    for (TrafficVolume trafficVolume : list) { 
     trafficVolume.checkedProperty().addListener((obs, wasChecked, isNowChecked) -> { 
      System.out.println("Checked property for " + trafficVolume.getName() + 
       " changed from "+wasChecked + " to " + isNowChecked); 
     } 
    } 

    // ... 
}
