How to add CheckBox’s to a TableView in JavaFX

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 );
