Question

我在JavaFX中相当新。我有一个包含多列的表，每行都有一个刷新按钮。每当我单击“刷新”按钮时，我都会尝试在已编辑的单元格中设置旧值。一个想法是将旧值传递给全局变量刷新按钮并进行设置。我可以得到旧值但是我怎样才能设置那个旧值？这是我的代码

 String old=null;

public void initialize(URL arg0, ResourceBundle arg1) {

            colName.setCellValueFactory(new PropertyValueFactory<ModelBrBuilding,String>("BranchName"));
            colName.setCellFactory(TextFieldTableCell.forTableColumn());
            colName.setOnEditCommit(
                    new EventHandler<CellEditEvent<ModelBrBuilding, String>>() {
                        @Override
                        public void handle(CellEditEvent<ModelBrBuilding, String> t) {
                     old= ((ModelBrBuilding) t.getTableView().getItems().get(
                                t.getTablePosition().getRow())
                                ).getBranchName();
                            ((ModelBrBuilding) t.getTableView().getItems().get(
                                    t.getTablePosition().getRow())
                                    ).setBranchName(t.getNewValue());
                        }
                    }
                );
colAction.setCellFactory(col -> {

                Button RefreshButton = new Button("Refresh");                                      
                hbox.getChildren().add(RefreshButton);

                TableCell<ModelBrBuilding, ModelBrBuilding> cell = new TableCell<ModelBrBuilding, ModelBrBuilding>() {
                    @Override
                    //Updating with the number of row 
                    public void updateItem(ModelBrBuilding building, boolean empty) {
                        super.updateItem(building, empty);
                        if (empty) {
                            setGraphic(null);
                        } else {
                            setGraphic(RefreshButton);
                        }
                    }

                };                                                  
                RefreshButton.setOnAction(event->{

                    //here I need to set the old value

                });                        
                return cell ;
            });

任何人都可以告诉我该怎么做？

最后，我发现我的答案正在运作

 RefreshButton.setOnAction(event->{             
                    ModelBrBuilding buildin= new ModelBrBuilding();                                             
                    int i=tableBuilding.getSelectionModel().getSelectedIndex();                    
                    buildin.setBranchName(old);

                    tableBuilding.getItems().set(i, buildin);               
                });
