TSearchAction Class | TSearchAction Members | StdActns Namespace | Description | See Also
Collapse All

Responds when components are created or destroyed.

Pascal
procedure Notification(AComponent: TComponent; Operation: TOperation); override;
C++
virtual __fastcall Notification(TComponent * AComponent, TOperation Operation);
Description

Do not call the Notification method in an application. Notification is called automatically when the component specified by AComponent is about to be inserted or removed, as specified by Operation.  

TBasicAction overrides the Notification method to check whether the component that is the value of the ActionComponent property is about to be freed. If so, it sets the ActionComponent property to nil (Delphi) or NULL (C++).
