class PASCALIMPLEMENTATION TCustomActionManager : public Vcl::Actnlist::TCustomActionList
TCustomActionManager is the base class for the TActionManager component.
TActionManager is a component that allows you to manage actions and categories of actions as UI elements at design-time and runtime. The action manager editor is the user interface for working with actions and categories of actions. You can visually add, delete, and regroup these UI elements on the action band components by dragging and dropping them from the Action Manager editor or by moving them around after they have been dropped on an action band.
