JavaFX TableView - 无法编辑

Question

我正在尝试在 TableView 上使用编辑功能。我用这个图作为引用: 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)。我已选中表和列的可编辑复选框(在场景生成器中)，但如果执行程序，我无法编辑这些值。我已经从 tut 下载了示例项目，并且在那里进行编辑...所以，在我的项目中 TextField 没有打开:( Controller :

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) {}
}

型号:

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 类:

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);
    }
}

这里是 fxml:

</AnchorPane>

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());
                ^
  required: Callback<TableColumn<StateData,String>,TableCell<StateData,String>>
  found: Callback<TableColumn<Object,String>,TableCell<Object,String>>
  reason: actual argument Callback<TableColumn<Object,String>,TableCell<Object,String>> cannot be converted to Callback<TableColumn<StateData,String>,TableCell<StateData,String>> by method invocation conversion
  where S,T are type-variables:
    S extends Object declared in class TableColumn
    T extends Object declared in class TableColumn

要使 TableView 可编辑，您还应该提供一个 CellFactory 来处理编辑控件的创建。

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