                    // - The Text area (a VBox); and
                    // - The Action buttons (another HBox).
                    // The Text area VBox has three lines:
                    // - The File Name;
                    // - The statistics; and
                    // - The File Path.
                    // The statistics are yet another HBox,
                    // as opposed to a simple Text string,
                    // so they can be separately enabled.
                    // The Nodes are declared and configured at this level
                    // (instead of within updateItem) so it only happens once per list item.
