我正在尝试在TableView. 我使用这个 tut 作为参考： http ://docs.oracle.com/javafx/2/ui_controls/table-view.htm# 但我使用 FXML 文件进行创建（使用 JavaFX 场景生成器）。我已经检查了表和列的可编辑复选框（在场景生成器中），但是如果我执行程序，我将无法编辑这些值。我已经从 tut 下载了示例项目，并且在那里进行了编辑……所以，在我的项目中，TextField没有打开 :( 控制器：

public class StatesPopupController implements Controllerable, Initializable {
    // <editor-fold desc="fxml import stuff" defaultstate="collapsed">
    @FXML //  fx:id="guiStatesTable"
    private TableView<StateData> guiStatesTable; // Value injected by FXMLLoader
    @FXML //  fx:id="guiColorColumn"
    private TableColumn<StateData, String> guiColorColumn; // Value injected by FXMLLoader
    @FXML //  fx:id="guiFontEffectColumn"
    private TableColumn<StateData, String> guiFontEffectColumn; // Value injected by FXMLLoader
    @FXML //  fx:id="guiUseColumn"
    private TableColumn<StateData, String> guiUseColumn; // Value injected by FXMLLoader
    @FXML //  fx:id="guiValueColumn"
    private TableColumn<StateData, String> guiValueColumn; // Value injected by FXMLLoader
    @FXML //  fx:id="guiStateAddColor"
    private TextField guiStateAddColor; // Value injected by FXMLLoader
    @FXML //  fx:id="guiStateAddFontEffect"
    private TextField guiStateAddFontEffect; // Value injected by FXMLLoader
    @FXML //  fx:id="guiStateAddUse"
    private TextField guiStateAddUse; // Value injected by FXMLLoader
    @FXML //  fx:id="guiStateAddValue"
    private TextField guiStateAddValue; // Value injected by FXMLLoader
// </editor-fold>

    private Modelable model = null;

    public StatesPopupController() {
        this.model = new StatesPopupModel();
    }

    @Override
    public Modelable getModel() {
        return model;
    }

    @Override
    public void initialize(URL url, ResourceBundle rb) {
        this.guiStatesTable.setEditable(true);
        this.guiValueColumn.setCellValueFactory(new PropertyValueFactory<StateData, String>("value"));
        this.guiColorColumn.setCellValueFactory(new PropertyValueFactory<StateData, String>("color"));
        this.guiUseColumn.setCellValueFactory(new PropertyValueFactory<StateData, String>("use"));
        this.guiFontEffectColumn.setCellValueFactory(new PropertyValueFactory<StateData, String>("fontEffect"));
        this.guiStatesTable.setItems(((StatesPopupModel)this.model).getTableData());
    }

    public void newAddBtnEvent(ActionEvent event {
        ((StatesPopupModel)this.model).addDataEntry(guiStateAddValue.getText(), guiStateAddColor.getText(), guiStateAddUse.getText(), guiStateAddFontEffect.getText());
        guiStateAddValue.clear();
        guiStateAddColor.clear();
        guiStateAddUse.clear();
        guiStateAddFontEffect.clear();
        this.guiStatesTable.setItems(((StatesPopupModel) this.model).getTableData());
    }

    public void newEditValueEvent(CellEditEvent<StateData, String> event) {

        ((StateData)event.getTableView().getItems().get(event.getTablePosition().getRow())).setValue(event.getNewValue());
    }

    public void newEditColorEvent(ActionEvent event) {
        System.out.print("asd");
    }

    public void newEditUseEvent(ActionEvent event) {}

    public void newEditFontEffectEvent(ActionEvent event) {}
}

模型：

public class StatesPopupModel implements Modelable {
    private ObservableList<StateData> data = FXCollections.observableArrayList(
        new StateData("inactive", "9", "permit", "plain"),
        new StateData("active", "2", "permit", "plain"),
        new StateData("unavailable", "7", "inhibit", "plain"),
        new StateData("available", "2", "permit", "plain"),
        new StateData("invisible", "2", "inhibit", "plain"),
        new StateData("visible", "4", "permit", "plain"),
        new StateData("controlSign", "10", "inhibit", "plain"),
        new StateData("label", "5", "permit", "plain"));

    public void addDataEntry(String value, String color, String use, String fontEffect) {
        data.add(new StateData(value, color, use, fontEffect));
    }

    public ObservableList<StateData> getTableData() {
        return data;
    }
}

StateData班级：

public class StateData
{
    private final SimpleStringProperty value;
    private final SimpleStringProperty color;
    private final SimpleStringProperty use;
    private final SimpleStringProperty fontEffect;

    public StateData(String value, String color, String use, String fontEffect) {
        this.value = new SimpleStringProperty(value);
        this.color = new SimpleStringProperty(color);
        this.use = new SimpleStringProperty(use);
        this.fontEffect = new SimpleStringProperty(fontEffect);
    }

    /**
     * @return the value
     */
    public String getValue() {
        return value.get();
    }

    /**
     * @param value the value to set
     */
    public void setValue(String value) {
        this.value.set(value);
    }

    /**
     * @return the color
     */
    public String getColor() {
        return color.get();
    }

    /**
     * @param color the color to set
     */
    public void setColor(String color) {
        this.color.set(color);
    }

    /**
     * @return the use
     */
    public String getUse() {
        return use.get();
    }

    /**
     * @param use the use to set
     */
    public void setUse(String use) {
        this.use.set(use);
    }

    /**
     * @return the fontEffect
     */
    public String getFontEffect() {
        return fontEffect.get();
    }

    /**
     * @param fontEffect the fontEffect to set
     */
    public void setFontEffect(String fontEffect) {
        this.fontEffect.set(fontEffect);
    }
}

欢迎任何帮助。

编辑：如果我使用：

.setCellFactory(TextFieldTableCell.forTableColumn());

我收到此错误：

error: method setCellFactory in class TableColumn<S,T> cannot be applied to given types;
    guiUseColumn.setCellFactory(TextFieldTableCell.forTableColumn());
                ^

为了使其TableView可编辑，您还应该提供一个CellFactory将处理编辑控件的创建。

您可以在此处找到教程的相应部分：http: //docs.oracle.com/javafx/2/ui_controls/table-view.htm#sthref119

试试这个：

....setCellFactory(TextFieldTableCell.<StateData>forTableColumn());

我有同样的问题，我没有找到一个合适的解决方案，分离 FXML 视图和控制器。我也想坚持这个模型。上面提到的例子对我不起作用。所以我稍微修改了这个教程。

该解决方案包括一个自定义TableCellFactory. 有必要更改TableCell并TextFieldTableCell添加以下内容：

cell.setConverter(new StringConverter<T>() {
            @Override
            public String toString(T object) {
                return object.toString();
            }
            @Override
            public T fromString(String string) {
                return (T) string;
            }
        });

在 Controller 中是处理更改的新方法。例如

@FXML
protected void changeFirstName(CellEditEvent<Person, String> event) {
    ((Person) event.getTableView().getItems().get(event.getTablePosition().getRow())).setFirstName(event.getNewValue());
}

参考在 FXML 文件中

<TableColumn fx:id="firstNameColumn" text="First Name" prefWidth="100" onEditCommit="#changeFirstName">

您可以在我的完整 Maven 示例中找到完整的更改。
