Hi, A type helper can change Self. I wondered how FPC 3.3.1 handles properties and got some unexpected results. Is this by design, a bug, or not-yet-implemented?
{$mode objfpc}{$modeswitch typehelpers} type TIntHlp = type helper for word procedure DoIt; end; TBig = class strict private FW: word; procedure SetW(const AValue: word); public property W: word read FW write SetW; end; var b: TBird; procedure TBig.SetW(const AValue: word); begin // not called by type helper writeln('TBig.SetW'); end; procedure TIntHlp.DoIt; begin writeln('TIntHlp.DoIt START ',Self,' w=',b.w); Self:=4; // changes b.FW directly writeln('TIntHlp.DoIt END ',Self,' w=',b.w); end; begin b:=TBig.Create; b.w.DoIt; end.
