Description

TCustomActionList - the ancestor class for TActionList. If you want to define your own action list class, you should derive it from this class.

TActionList, TAction, TActionLink and TContainedAction are used to centralize the implementation of user commands, and can then be linked to the appropriate button, menu or another component. This is an Object-Oriented programming strategy to reuse the code, as opposed to the Event-Oriented approach of writing an OnClick event for each component.
