[Bummi]

Probier mal das, das zeigt schön was passiert, heißt nicht umsonst private

Delphi-Quellcode:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TK1=Class
    private
    FX:Integer;
    public
    Constructor Create;
    Property x:Integer Read FX;
  End;
  TK2=Class(Tk1)
    private
    FX:Integer;
    public
    Constructor Create;

  End;

  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

{ TK1 }

constructor TK1.Create;
begin
   FX := 1;
end;

{ TK2 }

constructor TK2.Create;
begin
  inherited;
  Showmessage(IntToStr(FX));
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
 with TK2.Create do
    begin
      FX := 10;
      Showmessage(IntToStr(fx) + '-'+ IntToStr(x))
    end;

end;

end.
