Usage:[[TActionList
]]
ActionList should contain a list of standard actions associated with events on a Form; it is 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 (for example) an OnClick event for each component.
