RAD Studio VCL Reference
TCollectionItem Class

TCollectionItem represents an item in a collection.

TCollectionItem = class(TPersistent);
class TCollectionItem : public TPersistent;

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.
