我正在尝试使用TableView上的修改。
我用这个tut作为参考：
http://docs.oracle.com/javafx/2/ui_controls/table-view.htm#
但是我使用FXML文件进行创建（使用JavaFX Scene Builder）。
我检查了表格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，则无法编辑值。我从tut下载了示例项目，编辑工作在那里...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) {}
}
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：

欢迎每一位帮助。
编辑： 如果我正在使用：
.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

试试这个：
....setCellFactory(TextFieldTableCell.<StateData>forTableColumn());
答案 1 :(得分：2)
要使TableView可编辑，您还应提供CellFactory来处理编辑控件的创建。
您可以在此处找到相应的教程部分：http://docs.oracle.com/javafx/2/ui_controls/table-view.htm#sthref119

我有同样的问题，我没有找到一个分离的FXML视图和控制器的合适解决方案。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this tutorial。
该解决方案包含自定义var ReactDOM = require('react-dom');
var QuestionBox = require('./components/questionbox.js').QuestionBox;
ReactDOM.render(QuestionBox({}), document.getElementById('mount-node'));
。有必要将TableCellFactory更改为TableCell并添加以下内容：
TextFieldTableCell在Controller中是处理更改的新方法。例如
cell.setConverter(new StringConverter<T>() {
@Override
public String toString(T object) {
return object.toString();
}
@Override
public T fromString(String string) {
return (T) string;
}
});
参考在FXML文件中
@FXML
protected void changeFirstName(CellEditEvent<Person, String> event) {
((Person) event.getTableView().getItems().get(event.getTablePosition().getRow())).setFirstName(event.getNewValue());
}
您可以在我的full Maven example找到完整的更改。
