TOwnerDataListItem is a TListItem descendant which implements a list item used for a list view control in virtual mode. It is the singleton with the currently selected list item when the list view control has enabled its OwnerData property.
TOwnerDataListItem provides overridden methods which allow the list item to be maintained in an item cache instead of the Items collection for the list view control. The class instance is, however, still owned by the TListItems collection in the list view control.
An internal TOwnerDataListItem instance is allocated in the TCustomListView constructor for use in the control.
