How to determine if a method is of type TNotifyEvent

Problem/Question/Abstract:

If I am given a TPersistent object, and a method name, is there a way to determine if the name is an event of TNotifyEvent type? For example, given a TPersistent lMyObj and an event name, "OnDataChanged", how can I determine if OnDataChanged is a TNotifyEvent?

Answer:

function IsNotifyEvent(Sender: TObject; const Event: string): Boolean;
var
  PropInfo: PPropInfo;
  Method: TNotifyEvent;
begin
  Result := False;
  PropInfo := GetPropInfo(Sender.ClassInfo, Event);
  if not Assigned(PropInfo) then
    Exit;
  if PropInfo.PropType^.Kind <> tkMethod then
    Exit;
  Method := TNotifyEvent(GetMethodProp(Sender, PropInfo));
  Result := Assigned(Method);
end;
