javafx tableview oneditcommit 不会被自定义 cellfactory 调用？

Question

看看下面的工作代码:

    class MyType{
       SimpleStringProperty myname;
       SimpleObjectProperty<Color> mycolor;
    }

    TableColumn col;
    arr = FXCollections.observableArrayList(new ArrayList<MyType>());
    tblColName.setCellValueFactory(new PropertyValueFactory("myname"));
    // Use the cell-factory provided by TextFieldTableCell.
    tblColName.setCellFactory(TextFieldTableCell.forTableColumn());
    tblColName.setOnEditCommit(new EventHandler<TableColumn.CellEditEvent>() {
        @Override
        public void handle(TableColumn.CellEditEvent cellEditEvent) {
            ((MyType) cellEditEvent.getRowValue()).myname.set((String) cellEditEvent.getNewValue());
        }
    });

但是，一旦我使用自定义 TableCell，就不再调用 setOnEditCommit 中的代码:

public class ColorPickerTableCell<S> extends TableCell<S, Color>{
private ColorPicker cp;

public ColorPickerTableCell(){        
    cp = new ColorPicker(Color.BLACK);        
    cp.setOnAction(new EventHandler<ActionEvent>() {
        @Override
        public void handle(ActionEvent event) {
            commitEdit(cp.getValue());
            updateItem(cp.getValue(), isEmpty());
        }            
    });                
    setGraphic(cp);
    setContentDisplay(ContentDisplay.GRAPHIC_ONLY);
    setEditable(true);        
}     
@Override
protected void updateItem(Color item, boolean empty) {
    super.updateItem(item, empty);
    cp.setVisible(!empty);
    this.setItem(item);
}

public static <T> Callback<TableColumn<Color, T>, TableCell<Color, T>> forTableColumn(){
    return new Callback<TableColumn<Color, T>, TableCell<Color, T>>() {
        @Override
        public TableCell<Color, T> call(TableColumn<Color, T> colorTTableColumn) {
            return new ColorPickerTableCell();
        }
    };

}

对上面的代码稍作改动...

    TableColumn col;
    arr = FXCollections.observableArrayList(new ArrayList<MyType>());
    tblColName.setCellValueFactory(new PropertyValueFactory("myname"));
    // Use the cell-factory provided by TextFieldTableCell.
    tblColName.setCellFactory(ColorPickerTableCell.forTableColumn());
    tblColName.setOnEditCommit(new EventHandler<TableColumn.CellEditEvent>() {
        @Override
        public void handle(TableColumn.CellEditEvent cellEditEvent) {
            throw new NotImplementedException(); // is never thrown.
        }
    });

... 使代码不再有效。永远不会抛出异常。我认为我在 ColorPickerTableCell 的设计中做错了什么，但我无法想象是什么。如何让 JavaFX 调用我的 OnEditCommit ？

您需要先使用statEdit() 进入编辑状态； , 如果你现在提交一个事件将被触发
