Autoupdating rows in TableView from model

Question

I\'ve been looking information about refreshing data into a tableview. I was trying modifying directly the model, but I get a bug. I modify the model, but the table doesn\'t

Answer 1

There is a bug in TableView update (https://javafx-jira.kenai.com/browse/RT-22463). I had similar problem and after some search this is my workaround. I found that if the columns are removed and then re-added the table is updated.

public static <T,U> void refreshTableView(TableView<T> tableView, List<TableColumn<T,U>> columns, List<T> rows) {        
    tableView.getColumns().clear();
    tableView.getColumns().addAll(columns);

    ObservableList<T> list = FXCollections.observableArrayList(rows);
    tableView.setItems(list);
}

Example of usage:

refreshTableView(myTableView, Arrays.asList(col1, col2, col3), rows);

Answer 2

to make TableView able to track data changes you need to expose relevant fields as JavaFX properties. Add next methods to Person class from tutorial:

    public SimpleStringProperty firstNameProperty() {
        return firstName;
    }

    public SimpleStringProperty lastNameProperty() {
        return lastName;
    }

    public SimpleStringProperty emailProperty() {
        return email;
    }
