I try to make table cells editable. I managed to do this with two columns that have String values in it, but I can't make this with columns that represent Integer values.
Places with X is where compiler get the error:
The method setCellFactory(Callback<TableColumn<DataModel,Integer>,TableCell<DataModel,Integer>>) in the type TableColumn<DataModel,Integer> is not applicable for the arguments (Callback<TableColumn<DataModel,String>,TableCell<DataModel,String>>)
and places with XX is where compiler get the error:
The method setOnEditCommit(EventHandler<TableColumn.CellEditEvent<DataModel,Integer>>) in the type TableColumn<DataModel,Integer> is not applicable for the arguments ((CellEditEvent<DataModel, Integer> event) -> {})
Here's the code:
public void initialize(URL location, ResourceBundle resources)
{
//Tworzymy sobie kolumny, które będą odpowiadać oraz przyjmować konretne dane
TableColumn<DataModel, String> nameColumn = new TableColumn<DataModel, String>("Name");
nameColumn.setMinWidth(100);
TableColumn<DataModel, String> surnameColumn = new TableColumn<DataModel, String>("Surname");
surnameColumn.setMinWidth(100);
TableColumn<DataModel, Integer> ageColumn = new TableColumn<DataModel, Integer>("Age");
ageColumn.setMinWidth(100);
TableColumn<DataModel, Integer> telNumberColumn = new TableColumn<DataModel, Integer>("Tel. Number");
telNumberColumn.setMinWidth(100);
//dodajemy kolumny do okna
tableView.getColumns().addAll(nameColumn,surnameColumn,ageColumn,telNumberColumn);
//podajemy nazwy zmiennych, których wartości mają się wyświetlać w poszczególnych kolumnach
nameColumn.setCellValueFactory(new PropertyValueFactory<>("sName"));
surnameColumn.setCellValueFactory(new PropertyValueFactory<>("sSurname"));
ageColumn.setCellValueFactory(new PropertyValueFactory<>("iAge"));
telNumberColumn.setCellValueFactory(new PropertyValueFactory<>("iPhoneNumber"));
//Sprawiamy że poszczególne kolumny stają się edytowalne
nameColumn.setCellFactory(TextFieldTableCell.<DataModel>forTableColumn());
nameColumn.setOnEditCommit((CellEditEvent<DataModel, String> event) -> {
((DataModel) event.getTableView().getItems(). get(event.getTablePosition().getRow())). setsName(event.getNewValue());
});
surnameColumn.setCellFactory(TextFieldTableCell.<DataModel>forTableColumn());
surnameColumn.setOnEditCommit((CellEditEvent<DataModel, String> event) -> {
((DataModel) event.getTableView().getItems(). get(event.getTablePosition().getRow())). setsSurname(event.getNewValue());
});
X ageColumn.setCellFactory(TextFieldTableCell.<DataModel>forTableColumn());
XX ageColumn.setOnEditCommit((CellEditEvent<DataModel, Integer> event) -> {
// ((DataModel) event.getTableView().getItems(). get(event.getTablePosition().getRow())). setiAge(Integer.valueOf(event.getNewValue()));
});
X telNumberColumn.setCellFactory(TextFieldTableCell.<DataModel>forTableColumn());
XX telNumberColumn.setOnEditCommit((CellEditEvent<DataModel, Integer> event) -> {
// ((DataModel) event.getTableView().getItems(). get(event.getTablePosition().getRow())). setiPhoneNumber(Integer.valueOf(event.getNewValue()));
});
tableView.setPlaceholder(new Label("Pust tabelka!"));//jaki element dodać jeśli tabelka nie jest wyświetlona
tableView.setEditable(true);
tableView.setItems(dataList); //wczytujemy dane do przygotowanej tabelki
buttAdd.setOnAction((ActionEvent e) -> {
buttAddAction(e);
});
}
I'm taking Oracle TableView tutorial, and it's quite difficult. Help.
The issue is that TextFieldTableCell.forTableColumn()
is typed to a String value. See the default implementation:
public static <S> Callback<TableColumn<S,String>, TableCell<S,String>> forTableColumn() {
return forTableColumn(new DefaultStringConverter());
}
What you need is the TextFieldTableCell
with an IntegerStringConverter
, for example:
ageColumn.setCellFactory(TextFieldTableCell.<DataModel, Integer>forTableColumn(new IntegerStringConverter()));
