[dr. F.I.N.]

В моем примере контролы одной панели полностью копируются на вторую панель.

Код:

uses
  TypInfo;

procedure CopyObject(ObjFrom, ObjTo: TObject);
var
  PropInfos: PPropList;
  PropInfo: PPropInfo;
  Count, Loop: Integer;
  OrdVal: Longint;
  StrVal: String;
  FloatVal: Extended;
  MethodVal: TMethod;
begin
  Count := GetPropList(ObjFrom.ClassInfo, tkAny, nil);
  GetMem(PropInfos, Count * SizeOf(PPropInfo));
  try
    GetPropList(ObjFrom.ClassInfo, tkAny, PropInfos);
    for Loop := 0 to Count - 1 do
    begin
      PropInfo := GetPropInfo(ObjTo.ClassInfo, PropInfos^[Loop]^.Name);
      case PropInfos^[Loop]^.PropType^.Kind of
        tkInteger, tkChar, tkEnumeration,
        tkSet, tkClass{$ifdef Win32}, tkWChar{$endif}:
        begin
          OrdVal := GetOrdProp(ObjFrom, PropInfos^[Loop]);
          if Assigned(PropInfo) then
            SetOrdProp(ObjTo, PropInfo, OrdVal);
        end;
        tkFloat:
        begin

            SetFloatProp(ObjTo, PropInfo, FloatVal);
        end;

            SetMethodProp(ObjTo, PropInfo, MethodVal);
        end
      end
    end
  finally
    FreeMem(PropInfos, Count * SizeOf(PPropInfo));
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
var
  Original, Clone: TControl;
  OriginalClass: TClass;
  i: integer;
begin
  for i := 0 to Panel1.ControlCount - 1 do
  begin
    Original := Panel1.Controls[i];
    OriginalClass := Original.ClassType;
    Clone := TControlClass(OriginalClass).Create(Original.Owner);
    Clone.Parent := Panel2;
    CopyObject(Original, Clone);
  end;
