可以改的,Const
Orignwidth=800;
Orignheight=600;
implementation
{$R *.DFM}
procedure TForm1.FormCreate(Sender: TObject);
begin
scaled:=true;
if (screen.width<>orignwidth) then
begin
height:=longint(height)*longint(screen.height) div orignheight;
width:=longint(width)*longint(screen.width) div orignwidth;
scaleby(screen.width , orignwidth);
end;
end;
