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

TToolButtonActionLink inherits, from its ancestors, support for linking actions with the properties of components, generic controls, and windowed controls. TToolButtonActionLink adds support for linking the following properties to the appropriate behavior for a tool button control: 

Checked 

ImageIndex 

Not all actions correspond to properties and events of the same name. For example, the tool button 'down' property is linked to the 'checked' action.
