Description
THelpAction is the base class for action objects that interact with the help system.
THelpAction implements the common behavior for actions that work the help system. Each descendant class performs a specific help function. Do not use THelpAction directly in an application. Instead, use a THelpAction descendant such as THelpContents, THelpContextAction, THelpOnHelp, or THelpTopicSearch.
THelpAction ensures that the action is enabled as long as there is an application object to pass commands on to a registered help system. THelpAction descendants override the ExecuteTarget method to execute their specific help command.
