I want to create a OnMouseOver Listener to cells of a specific column of a TableView, such that a popup window should appeared with some message, when I hover to it's cells. This is how I am creating a table and its columns.

private TableView<Stock> stockTable = new TableView<>();
ObservableList columns = stockTable.getColumns();

public TableColumn createTextColumn(String columnName, String columnCaption,BooleanProperty editingStarted) {
    TableColumn column = new TableColumn(columnCaption);
    column.setCellValueFactory(new PropertyValueFactory<>(columnName));
    column.setCellFactory(TextFieldTableCell.forTableColumn());
    return column;
}

final TableColumn nameColumn 
                         = createTextColumn("name", "Product Name", editingStarted);
columns.add(nameColumn);

So is it possible to do it. I know how to create listeners for rows. But I found nothing on internet on listening to cells of table. Thanks in advance for any help.

The above example also displays the label when it's empty. This small change will fix this ...

                    if (event.getEventType() == MouseEvent.MOUSE_EXITED) {
                        popup.hide();
                    } else if (event.getEventType() == MouseEvent.MOUSE_ENTERED) {
                        if(result.getText() != null) {
                            if (!"".equals(result.getText())) {
                                popup.show(result, event.getScreenX() + 10, event.getScreenY());
                            }
                        }
                    }
