→ TObjectList

PURPOSE:Store shapes in ordered list for fast indexed access. Provides TObjectList container for layer's shape collection. Used by layer Items property for shape enumeration and direct access.

BEHAVIOR:Wrapper class around generic TObjectList. Maintains shape order, supports indexed access (0-based), iteration via for-in loops. Framework-owned (not typically created directly).

USAGE:Access shapes:shape := layer.Items[0]; { first shape }Iterate:for shape in layer.Items do { process shape }

CONSTRAINTS:Framework-managed container. Not typically instantiated directly. Defined as explicit class (not alias) due to Delphi/C++Builder < XE8 compatibility requirements.
