[Lazarus] List the procedures of a object.

[Everton Vieira]

I just did, the real case just saved me to do about 10.000 lines of code in
a very tedious job.

Became like this:

unit Unit1;
{$mode objfpc}{$M+}
interface
uses
  Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs, StdCtrls;
type
  { TTeste }
  TTeste = class
    published
      procedure Proc;
    end;
type
  { TForm1 }
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { private declarations }
  public
    { public declarations }
  end;
var
  Form1: TForm1;
type
  TProc = procedure of object;
implementation
procedure DoProc(Sender: TObject);
var
  M : TMethod;
  P: TProc;
begin
  M.Data := Pointer(Sender) ;
  M.Code := Sender.MethodAddress('Proc') ;
  P := TProc(M);
  P;
end;
{ TTeste }
procedure TTeste.Proc;
begin
  ShowMessage('oi');
end;
{$R *.lfm}
{ TForm1 }
procedure TForm1.Button1Click(Sender: TObject);
begin
  DoProc(TTeste.Create);
end;
end.
