# NCWidgetListViewDelegate

The interface for handling content display and editing in the list view of a macOS Today widget.

## Declaration

```swift
protocol NCWidgetListViewDelegate : NSObjectProtocol
```

## Overview

Overview The NCWidgetListViewDelegate protocol defines methods that handle content display and editing in the list view of a Today widget. The delegate of an NCWidgetListViewController must adopt the NCWidgetListViewDelegate protocol. The single required method in the protocol, widgetList(_:viewControllerForRow:), creates a view controller for the contents of one row in the widget’s list view. Optional methods in the NCWidgetListViewDelegate protocol support editing actions, such as adding a new list item and reordering or deleting list rows.
