Unit
IB_Components

Declaration
TIB_DataLink = class(TIB_Component)

Description
This component is used to make another component or control data aware.

It is the base class of many specialized links tailored to suit more specific needs.

It is typically used as a contained or owned object that gives a clean interface to interact with the data. See the IB_Controls and IB_Grid units to see how it is implemented.
