TButtonActionLink is designed to specifically link actions to button control clients. TButtonActionLink overrides methods to determine whether the action and client are linked, and to ensure that action events are appropriate for properties of button control clients. 

TButtonActionLink inherits, from its ancestors, support for linking actions with the properties of components, generic controls, and windowed controls. TButtonActionLink adds support for linking the checked property to the appropriate property of a button control.
