Programmatically change the TableView row appearance

If you don’t want the reusability of the solution I posted here, this is really the same thing but using an anonymous inner class for the row factory instead of a standalone class. Perhaps the code is easier to follow as it’s all in one place. It’s kind of a hybrid between Jonathan’s solution and mine, but will automatically update the highlights without forcing it with a sort.

I used a list of integers so it supports multiple selection, but if you don’t need that you could obviously just use an IntegerProperty instead.

Here’s the row factory:

    final ObservableList<Integer> highlightRows = FXCollections.observableArrayList();

    table.setRowFactory(new Callback<TableView<Person>, TableRow<Person>>() {
        @Override
        public TableRow<Person> call(TableView<Person> tableView) {
            final TableRow<Person> row = new TableRow<Person>() {
                @Override
                protected void updateItem(Person person, boolean empty){
                    super.updateItem(person, empty);
                    if (highlightRows.contains(getIndex())) {
                        if (! getStyleClass().contains("highlightedRow")) {
                            getStyleClass().add("highlightedRow");
                        }
                    } else {
                        getStyleClass().removeAll(Collections.singleton("highlightedRow"));
                    }
                }
            };
            highlightRows.addListener(new ListChangeListener<Integer>() {
                @Override
                public void onChanged(Change<? extends Integer> change) {
                    if (highlightRows.contains(row.getIndex())) {
                        if (! row.getStyleClass().contains("highlightedRow")) {
                            row.getStyleClass().add("highlightedRow");
                        }
                    } else {
                        row.getStyleClass().removeAll(Collections.singleton("highlightedRow"));
                    }
                }
            });
            return row;
        }
    });

And here are what some buttons might look like:

    final Button btnHighlight = new Button("Highlight");
    btnHighlight.disableProperty().bind(Bindings.isEmpty(table.getSelectionModel().getSelectedIndices()));
    btnHighlight.setOnAction(new EventHandler<ActionEvent>() {
        @Override
        public void handle(ActionEvent event) {
            highlightRows.setAll(table.getSelectionModel().getSelectedIndices());
        }
    });

    final Button btnClearHighlight = new Button("Clear Highlights");
    btnClearHighlight.disableProperty().bind(Bindings.isEmpty(highlightRows));
    btnClearHighlight.setOnAction(new EventHandler<ActionEvent>() {
        @Override
        public void handle(ActionEvent event) {
            highlightRows.clear();
        }
    });
