Question

我有两列，一个是状态，是我点击的那个，另一个是 Approved By ，它应该在Button动作事件后更新。我是通过

尝试setOnAction

getTableView().getSelectionModel().getSelectedItem().setApprovedby("User");

但它不起作用。

请帮助我在Button同一行动作事件后如何在 Approved By 列中显示文本。它看起来如下所示

//这是 Status 列的setCellFactory的按钮单元格代码

public class Buttoncell implements Callback<TableColumn<thamso, Button>, TableCell<thamso, Button>> {

    @Override
    public TableCell<thamso, Button> call(TableColumn<thamso, Button> arg) {

        TableCell<thamso, Button> cell = new TableCell<thamso, Button>() {
        // TODO Auto-generated method stub

            protected void updateItem(Button item, boolean empty) {
                if (!empty) {
                    item.setOnAction(e -> {
                        getTableView().getSelectionModel().getSelectedItem().setApprovedby("User");

                        item.setText("Approved");;

                        item.getStyleClass().removeAll("addBobOk, focus");

                        item.getStyleClass().add("addBobOk");

                    });
                }
                setGraphic(item);
            }
        };
        return cell;
    }
}

//这是

Answer 1

在大多数情况下，将Node存储在项目类中并不是一个好主意。在这种情况下，这不是一个好主意。您将数据的可视化表示与数据本身混合在一起。

另一列中的单元格无法更新，因为approvedby属性不可观察。对此属性使用StringProperty以确保TableView可以观察到对该属性的更改：

thamso

public class thamso {

    ...
    private StringProperty approvedby;
    //private Button statusaproval;
    ...

    public thamso(String projectid, String model, String drawingname, String partname, int quantity, int spare,
            int qtyperset, int no, String material, float weight, String note, String drawing, int rev,
            String hyperlink, String importby, String dateimport, String approvedby, String dateapproval) {
        ...

        this.approvedby = new SimpleStringProperty(approvedby);
        this.dateapproval = dateapproval;
    }


    public String getApprovedby() {
        return approvedby.get();
    }

    public void setApprovedby(String approvedby) {
        this.approvedby.set(approvedby);
    }

    public StringProperty approvedbyProperty() {
        return this.approvedby;
    }

    ...
}

Engineeringcontroller

public class Engineeringcontroller {

    ...

    @FXML
    public TableColumn<thamso, String> approvedby;

    ...

    @FXML
    private TableColumn<thamso, String> status;

    ...

    @FXML
    public void initialize() {
        ...

        approvedby.setCellValueFactory(new PropertyValueFactory<>("approvedby"));
        approvedby.setCellFactory(TextFieldTableCell.<thamso>forTableColumn());

        ...

        status.setCellValueFactory(new PropertyValueFactory<>("approvedby"));
        status.setCellFactory(new Buttoncell());

        ...
    }

    ...

}

扣式

public class Buttoncell implements Callback<TableColumn<thamso, String>, TableCell<thamso, String>> {

    @Override
    public TableCell<thamso, String> call(TableColumn<thamso, String> arg) {

        TableCell<thamso, String> cell = new TableCell<thamso, String>() {

            private final Button button;

            {
                button = new Button();
                button.setOnAction(evt -> {
                    thamso item = (thamso) getTableRow().getItem();
                    item.setApprovedby("User");:
                });
            }

            @Override
            protected void updateItem(String item, boolean empty) {
                if (empty) {
                    // remove button
                    setGraphic(null);
                } else {
                    // set up button based on item
                    button.getStyleClass().remove("addBobOk");
                    if (item != null && !item.isEmpty()) {
                        button.getStyleClass().add("addBobOk");
                        button.setText("Approved");
                    } else {
                        button.setText("pending approval");
                    }
                    setGraphic(button);
                }
            }
        };
        return cell;
    }
}

注意：在上面的代码中，我假设如果有人请接受thamso！= ""已批准。可以使用例如相反，它是一个布尔属性。
