程序参考:
unit Qrline;interfaceuses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
       Quickrpt; 
type
  TQRLineStyle=(QRLineH,QRLineV,QRLineC,QRLineCR);
  TQRLine = class(TQRPrintable)
  private
    { Private declarations }
    FPen:TPen;
    FLineStyle:TQRLineStyle;
  protected
    { Protected declarations }
    procedure setPen(value:TPen);
    procedure setLineStyle(value:TQRLineStyle);
    procedure onPenChanged(Sender:TObject);
  public
    { Public declarations }
    constructor Create(AOwner:TComponent);override;

  published
    { Published declarations }
    property Pen:TPen read FPen write setPen;

end;destructor TQRLine.Destroy;
begin
  FPen.Free;
  inherited Destroy;
end;procedure TQRLine.setPen(value:TPen);
begin
  FPen.Assign(value);
  invalidate;

  end;
end;procedure TQRLine.onPenChanged(Sender:TObject);

  with Canvas do
