The ControlDestroyed method or DelphiVCL.Application.ControlDestroyed is used to notify the application when a control is destroyed.
ControlDestroyed is for internal use and is called automatically by TControl. Do not call it directly.
ControlDestroyed notifies the application that the control passed as the Control parameter has been destroyed, so that the properties which refer to controls, such as MainForm and ActiveCustomForm, can be updated to specify a valid object or nil (Delphi) or NULL (C++).
