In my Java Desktop Application I have a TableView in which I want to have a column with CheckBoxes.
I did find where this has been done http://www.jonathangiles.net/javafx/2.0/CellFactories/ but as the download is not available and because I don't know how soon Jonathan Giles will answer my email I thought I'd ask...
How do I put a CheckBox in a cell of my TableView?
You need to set a CellFactory on the TableColumn.
For example:
Callback<TableColumn<TableData, Boolean>, TableCell<TableData, Boolean>> booleanCellFactory =
new Callback<TableColumn<TableData, Boolean>, TableCell<TableData, Boolean>>() {
@Override
public TableCell<TableData, Boolean> call(TableColumn<TableData, Boolean> p) {
return new BooleanCell();
}
};
active.setCellValueFactory(new PropertyValueFactory<TableData,Boolean>("active"));
active.setCellFactory(booleanCellFactory);
class BooleanCell extends TableCell<TableData, Boolean> {
private CheckBox checkBox;
public BooleanCell() {
checkBox = new CheckBox();
checkBox.setDisable(true);
checkBox.selectedProperty().addListener(new ChangeListener<Boolean> () {
public void changed(ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) {
if(isEditing())
commitEdit(newValue == null ? false : newValue);
}
});
this.setGraphic(checkBox);
this.setContentDisplay(ContentDisplay.GRAPHIC_ONLY);
this.setEditable(true);
}
@Override
public void startEdit() {
super.startEdit();
if (isEmpty()) {
return;
}
checkBox.setDisable(false);
checkBox.requestFocus();
}
@Override
public void cancelEdit() {
super.cancelEdit();
checkBox.setDisable(true);
}
public void commitEdit(Boolean value) {
super.commitEdit(value);
checkBox.setDisable(true);
}
@Override
public void updateItem(Boolean item, boolean empty) {
super.updateItem(item, empty);
if (!isEmpty()) {
checkBox.setSelected(item);
}
}
}
Uses javafx.scene.control.cell.CheckBoxTableCell<S,T> and the work's done !
ObservableList< TableColumn< RSSReader, ? >> columns =
_rssStreamsView.getColumns();
[...]
TableColumn< RSSReader, Boolean > loadedColumn = new TableColumn<>( "Loaded" );
loadedColumn.setCellValueFactory(
new Callback<CellDataFeatures<RSSReader,Boolean>,ObservableValue<Boolean>>(){
@Override public
ObservableValue<Boolean> call( CellDataFeatures<RSSReader,Boolean> p ){
return p.getValue().getCompleted(); }});
loadedColumn.setCellFactory(
new Callback<TableColumn<RSSReader,Boolean>,TableCell<RSSReader,Boolean>>(){
@Override public
TableCell<RSSReader,Boolean> call( TableColumn<RSSReader,Boolean> p ){
return new CheckBoxTableCell<>(); }});
[...]
columns.add( loadedColumn );
UPDATE: same code using Java 8 lambda expressions
ObservableList< TableColumn< RSSReader, ? >> columns =
_rssStreamsView.getColumns();
[...]
TableColumn< RSSReader, Boolean > loadedColumn = new TableColumn<>( "Loaded" );
loadedColumn.setCellValueFactory( f -> f.getValue().getCompleted());
loadedColumn.setCellFactory( tc -> new CheckBoxTableCell<>());
[...]
columns.add( loadedColumn );
Lines count is divided by two! (16 ==> 8)
UPDATE: same code using Java 10 "var" contextual word
var columns = _rssStreamsView.getColumns();
[...]
var loadedColumn = new TableColumn<RSSReader, Boolean>( "Loaded" );
loadedColumn.setCellValueFactory( f -> f.getValue().getCompleted());
loadedColumn.setCellFactory( tc -> new CheckBoxTableCell<>());
[...]
columns.add( loadedColumn );

TableColumn select = new TableColumn("CheckBox");
select.setMinWidth(200);
select.setCellValueFactory(new Callback<TableColumn.CellDataFeatures<Person, CheckBox>, ObservableValue<CheckBox>>() {
@Override
public ObservableValue<CheckBox> call(
TableColumn.CellDataFeatures<Person, CheckBox> arg0) {
Person user = arg0.getValue();
CheckBox checkBox = new CheckBox();
checkBox.selectedProperty().setValue(user.isSelected());
checkBox.selectedProperty().addListener(new ChangeListener<Boolean>() {
public void changed(ObservableValue<? extends Boolean> ov,
Boolean old_val, Boolean new_val) {
user.setSelected(new_val);
}
});
return new SimpleObjectProperty<CheckBox>(checkBox);
}
});
table.getColumns().addAll( select);
The simplest solution is probably to do it in FXML:
First create the class below:
public class CheckBoxCellFactory<S, T>
implements Callback<TableColumn<S, T>, TableCell<S, T>> {
@Override public TableCell<S, T> call(TableColumn<S, T> p) {
return new CheckBoxTableCell<>();
}
}
Then include a cell factory in your FXML:
<TableColumn text="Select" fx:id="selectColumn" >
<cellFactory>
<CheckBoxCellFactory/>
</cellFactory>
</TableColumn>
You also need to add an import in the FXML, such as <?import com.assylias.factories.*?>
Bonus: you can make the factory more customisable, for example to determine where the checkbox should appear, by adding fields to the CheckBoxCellFactory class, such as:
private Pos alignment = Pos.CENTER;
public Pos getAlignment() { return alignment; }
public void setAlignment(Pos alignment) { this.alignment = alignment; }
And the FXML:
<cellFactory>
<CheckBoxCellFactory alignment="BOTTOM_RIGHT"/>
</cellFactory>
Small and simple.
row.setCellValueFactory(c -> new SimpleBooleanProperty(c.getValue().getIsDefault()));
row.setCellFactory(tc -> new CheckBoxTableCell<>());There is a very simple way of doing this, you don't need to modify your model class with SimpleBooleanProperty or whatever, just follow these steps:
1 - Suppose you have a "Person" object with a isUnemployed method:
public class Person {
private String name;
private Boolean unemployed;
public String getName(){return this.name;}
public void setName(String name){this.name = name;}
public Boolean isUnemployed(){return this.unemployed;}
public void setUnemployed(Boolean unemployed){this.unemployed = unemployed;}
}
2 - Create the callback class
import javafx.beans.property.SimpleObjectProperty;
import javafx.beans.value.ObservableValue;
import javafx.scene.control.CheckBox;
import javafx.scene.control.TableColumn;
import javafx.util.Callback;
public class PersonUnemployedValueFactory implements Callback<TableColumn.CellDataFeatures<Person, CheckBox>, ObservableValue<CheckBox>> {
@Override
public ObservableValue<CheckBox> call(TableColumn.CellDataFeatures<Person, CheckBox> param) {
Person person = param.getValue();
CheckBox checkBox = new CheckBox();
checkBox.selectedProperty().setValue(person.isUnemployed());
checkBox.selectedProperty().addListener((ov, old_val, new_val) -> {
person.setUnemployed(new_val);
});
return new SimpleObjectProperty<>(checkBox);
}
}
3 - Bind the callback to the table column
If you use FXML, put the callback class inside your column:
<TableView fx:id="personList" prefHeight="200.0" prefWidth="200.0">
<columns>
<TableColumn prefWidth="196.0" text="Unemployed">
<cellValueFactory>
<PersonUnemployedValueFactory/> <!--This is how the magic happens-->
</cellValueFactory>
</TableColumn>
...
</columns>
</TableView>
Don't forget to import the class in your FXML:
<?import org.yourcompany.yourapp.util.PersonUnemployedValueFactory?>
Without FXML, do it like this:
TableColumn<Person, CheckBox> column = (TableColumn<Person, CheckBox>) personTable.getColumns().get(0);
column.setCellValueFactory(new PersonUnemployedValueFactory());
4 - That's it
Everything should work as expected, with the value being set to the backing bean when you click on the checkbox, and the checkbox value correctly being set when you load the items list in your table.
The simplest solution in order to have an EDITABLE checkbox linked to the model is:
Assuming that you have a Person model class with two fields, a "name" string and the "selected" boolean value:
public class Person {
private final SimpleBooleanProperty selected;
private final SimpleStringProperty name;
public Person(String name) {
this.selected = new SimpleBooleanProperty(false);
this.name = new SimpleStringProperty(name);
}
public boolean isSelected() {
return selected.get();
}
public SimpleBooleanProperty selectedProperty() {
return selected;
}
public void setSelected(boolean selected) {
this.selected.set(selected);
}
public String getName() {
return name.get();
}
public SimpleStringProperty nameProperty() {
return name;
}
public void setName(String name) {
this.name.set(name);
}
}
All you have to do in the controller is:
@FXML private TableColumn<Person, Boolean> checkBoxCol;
@FXML private TableColumn<Person, String> nameCol;
@Override
public void initialize(URL location, ResourceBundle resources) {
checkBoxCol.setCellFactory(
CheckBoxTableCell.forTableColumn(checkBoxCol)
);
checkBoxCol.setCellValueFactory(
new PropertyValueFactory<>("selected")
);
nameCol.setCellValueFactory(
new PropertyValueFactory<>("name")
);
}

This is the way is do it
tbcSingleton.setCellValueFactory(data -> data.getValue().singletonProperty());
tbcSingleton.setCellFactory( param -> {
return new TableCell<FXMLController, Boolean>(){
{
setAlignment(Pos.CENTER);
}
protected void updateItem(Boolean item, boolean empty){
if(!empty && item!=null) {
CheckBox cb = new CheckBox();
cb.setSelected(item);
cb.setFocusTraversable(false);
cb.selectedProperty().addListener((obs,old,niu)->listaFXMLController.get(getIndex()).setSingleton(niu));
setGraphic(cb);
}else
setGraphic(null);
}
};
});
cb.setFocusTraversable(false) is necesary to prevent focus getting stuck on it.
setGraphic(null) is necesary to erase anything left behind after deleting an item or whenever the source list changes
Heres another one with a ToggleGroup and ToggleButtons
tbcTipoControlador.setCellValueFactory(data -> data.getValue().controllerTypeProperty());
tbcTipoControlador.setCellFactory( param -> {
return new TableCell<FXMLController, ControllerType>() {
{
setAlignment(Pos.CENTER);
}
protected void updateItem(ControllerType item, boolean empty){
if(!empty && item!=null) {
ToggleButton tbModal = new ToggleButton("Modal");
tbModal.selectedProperty().addListener((obs,old,niu)->{
if(niu)
listaFXMLController.get(getIndex()).setControllerType(ControllerType.MODAL);
});
tbModal.setSelected(item.equals(ControllerType.MODAL));
ToggleButton tbPlain = new ToggleButton("Plain");
tbPlain.selectedProperty().addListener((obs,old,niu)->{
if(niu)
listaFXMLController.get(getIndex()).setControllerType(ControllerType.PLAIN);
});
tbPlain.setSelected(item.equals(ControllerType.PLAIN));
ToggleButton tbApplication= new ToggleButton("Application");
tbApplication.selectedProperty().addListener((obs,old,niu)->{
if(niu)
listaFXMLController.get(getIndex()).setControllerType(ControllerType.APPLICATION);
});
tbApplication.setSelected(item.equals(ControllerType.APPLICATION));
ToggleGroup gp = new ToggleGroup();
tbModal.setFocusTraversable(false);
tbPlain.setFocusTraversable(false);
tbApplication.setFocusTraversable(false);
tbModal.setPrefWidth(120);
tbPlain.setPrefWidth(120);
tbApplication.setPrefWidth(120);
gp.getToggles().addAll(tbModal,tbPlain,tbApplication);
HBox hb = new HBox();
hb.setAlignment(Pos.CENTER);
hb.getChildren().addAll(tbModal,tbPlain,tbApplication);
setGraphic(hb);
}else
setGraphic(null);
}
};
});
I did some test and memory consumption is basically the same as using a ComboBoxTableCell
This is how my little application looks (sry, my main language is Spanish and i build it for personal use)
Inspired from the previous answers, this is the shortest possible version, I think.
checkBoxColumn.setCellValueFactory(c -> {
c.getValue().booleanProperty().addListener((ch, o, n) -> {
// do something
});
return c.getValue().booleanProperty();
});
checkBoxColumn.setCellFactory(CheckBoxTableCell.forTableColumn(checkBoxColumn));
Here's a 3rd party lib that will do it http://www.jonathangiles.net/javafx/2.0/CellFactories/docs/api/net/jonathangiles/javafx/control/cell/tableview/CheckBoxTableCell.html
for me, works with this solution:
Callback<TableColumn, TableCell> checkboxCellFactory = new Callback<TableColumn, TableCell>() {
@Override
public TableCell call(TableColumn p) {
return new CheckboxCell();
}
};
TableColumn selectColumn = (TableColumn) tbvDatos.getColumns().get(1);
selectColumn.setCellValueFactory(new PropertyValueFactory("selected"));
selectColumn.setCellFactory(checkboxCellFactory);
and the tableCell:
public class CheckboxCell extends TableCell<RowData, Boolean> {
CheckBox checkbox;
@Override
protected void updateItem(Boolean arg0, boolean arg1) {
super.updateItem(arg0, arg1);
paintCell();
}
private void paintCell() {
if (checkbox == null) {
checkbox = new CheckBox();
checkbox.selectedProperty().addListener(new ChangeListener<Boolean>() {
@Override
public void changed(ObservableValue<? extends Boolean> ov,
Boolean old_val, Boolean new_val) {
setItem(new_val);
((RowData)getTableView().getItems().get(getTableRow().getIndex())).setSelected(new_val);
}
});
}
checkbox.setSelected(getValue());
setText(null);
setGraphic(checkbox);
}
private Boolean getValue() {
return getItem() == null ? false : getItem();
}
}
if you dont need to make the checkbox with edit event
