Description
TCollectionItem represents an item in a collection.
A TCollection holds a group of TCollectionItem objects. TCollectionItems are created and destroyed by TCollection's Add and Clear methods. Each TCollectionItem has a Collection property that points to the TCollection object to which the item belongs.
Objects descending from TCollection can contain objects descending from TCollectionItem. For example, a TDBGridColumns object contains TColumn objects; these two classes are used by TDBGrid to represent grid columns.
