Anonymous Methods Used as Events

New features since Delphi 7 > Anonymous Methods > Anonymous Methods Used as Events

Delphi

type

  TMyEvent = reference to procedure;

property OnEvent: TMyEvent read FOnEvent write FOnEvent;

C++ portable

d2c::callback<void()> OnEvent;

if (OnEvent)

  OnEvent();

C++Builder

System::Sysutils::_di_TProc OnEvent;

if (OnEvent != nullptr)

  OnEvent->Invoke();

Anonymous-method-based events are stored and invoked like other callable values.
