TAddItemEvent specifies an event handler signalled when an item is added to a shell control. TAddItemEvent is the type used to implement the OnAddItem event handler in TCustomShellListView and TCustomShellTreeView.
Applications must implement and assign an object procedure using the signature for the event to respond to the notification. The Sender argument must be cast to the correct class type to access properties and method in the control. Set the value in the CanAdd variable parameter to False to prevent the item from being added in the calling procedure.
