Schriftgröße von Fenstergröße abhängig machen

[xilos]

dankeschön...ich habs jetzt mal versucht aber irgendwie funktionierts nicht ^^
stimmt die implementierung so?

Delphi-Quellcode:

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    lblMinuten: TLabel;
    lblSekunden: TLabel;
    btnStarten: TButton;
    Timer1: TTimer;
    Button2: TButton;
    Button3: TButton;
    Button4: TButton;
    Button5: TButton;
    Label1: TLabel;
    Label2: TLabel;
    StatusBar1: TStatusBar;

end;

  end
