Description

TComponentList is a TObjectList descendent which has as the default array property TComponents instead of objects. It overrides some methods so only components can be added.

In difference with TObjectList, TComponentList removes any TComponent from the list if the TComponent instance was freed externally. It uses the FreeNotification mechanism for this.
