Accessing the GUI from events in MultiThreaded mode

[zxplzzc]

How can I  write the following codes correctly?
procedure TMainForm.RtcHttpClient1ConnectError(Sender: TRtcConnection;E: Exception);
begin
  if not Sender.inMainThread then
     Sender.Sync(RtcHttpClient1ConnectError);
  else
  begin
    RzStatusPane1.Caption:=E.Message;
  end;
end;

Thanks!

I see:
  Sender.Sync(RtcHttpClient1ConnectError,E)

Correct. The Sync method needs to be called with the event to be synchronized and all the parameters which that event is receiving, except "Sender".
