Bug Needed的解决方法 - 在向表底部添加内容时停止TableView小滚动

Question

我有一个TableView，每100毫秒左右添加一次内容，大约5或10分钟。

在添加该内容时，如果您不在表的顶部或底部，则每次添加项时内容都会滚动一点。

下面是一个非常简单且可运行的问题示例。

有没有办法让这个表在添加内容时保持静止，否则不会损害可滚动性/可用性？

public class TableAutoScroll extends Application {

    @Override
    public void start( Stage stage ) throws Exception {

        ObservableList<Person> tableContent = FXCollections.observableArrayList( new ArrayList <Person>() );

        TableColumn <Person, String> firstNameColumn = new TableColumn <> ( "First Name" );
        TableColumn <Person, String> LastNameColumn = new TableColumn <> ( "Last Name" );
        TableColumn <Person, String> addressColumn = new TableColumn <> ( "Address" );

        firstNameColumn.setCellValueFactory( new PropertyValueFactory <Person, String>( "firstName" ) );
        LastNameColumn.setCellValueFactory( new PropertyValueFactory <Person, String>( "lastName" ) );
        addressColumn.setCellValueFactory( new PropertyValueFactory <Person, String>( "address" ) );

        TableView <Person> tableView = new TableView <> ();
        tableView.getColumns().addAll( firstNameColumn, LastNameColumn, addressColumn );
        tableView.setColumnResizePolicy( TableView.CONSTRAINED_RESIZE_POLICY );
        tableView.setItems( tableContent );

        for ( int k = 0; k < 500; k ++ ) {
            tableContent.add ( new Person ( "Dummy", "Person", k + " Sesame Street" ) );
        }

        tableView.scrollTo( 200 );

        BorderPane pane = new BorderPane( tableView );
        stage.setScene( new Scene( pane, 800, 400 ) );
        stage.show();

        Thread populateThread = new Thread ( () -> {
            for ( int k = 0; k < 10000; k ++ ) {

                Platform.runLater( ()-> tableContent.add( addMe ) );
                try {

                } catch (InterruptedException e) {}
            }
        });

        populateThread.setDaemon ( true );
        populateThread.start();

    }

    public static void main ( String[] args ) {
        launch ( args );
    }
