JavaFX TableView-无法编辑 [英] JavaFX TableView - can not be edited
问题描述
我正在尝试在TableView
上使用编辑.
我用这个tut作为参考:
http://docs.oracle.com/javafx/2/ui_controls /table-view.htm#
但是我正在使用FXML文件进行创建(使用JavaFX Scene Builder).
我已经检查了表和列的可编辑复选框(在Scene Builder中),但是如果执行该程序,则无法编辑值.我已经从tut下载了示例项目,并且在那里可以进行编辑...因此,在我的项目中,TextField
没有打开:(
控制器:
I am trying to use the edit on a TableView
.
i used this tut as reference:
http://docs.oracle.com/javafx/2/ui_controls/table-view.htm#
but I am using a FXML file for the creation (with the JavaFX Scene Builder).
I have checked the editable checkboxes for the table and the columns (in the Scene Builder), but if I execute the program, I am not able to edit the values. I have downloaded the example project from the tut and the editing works there... so, in my project the TextField
doesn´t get opened :(
The 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:

欢迎所有帮助.
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
推荐答案
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.
To make TableView
editable you should also provide a CellFactory
which will handle creation of the editing controls.
