A neebie problem with Pen and CanvasPolygon

Hello,

I am discovering canvas, but up to now, I cannot see any Pen drawing
when I draw a polygon. By the way, filling with the brush is effective.

Any help will be welcome !

-------------------------------- 
(...)
my $cp; # canvas polygon
my $pa; # point array
my $brush;
my $pen;
# ------------------------------------
(..)
$pen=Qt::Pen( &red, &SolidLine );
$brush=Qt::Brush( &green, &Dense6Pattern );
(..)
 $cp=Qt::CanvasPolygon($canvas);
 $cp->setBrush($brush);
 $cp->setPen($pen);
 $cp->setZ(255);

 # -- set the point array
 $pa=Qt::PointArray(15);
    $pa->setPoint(0,0,0);
    $pa->setPoint(1,100,100);
    $pa->setPoint(2,100,200);
    $pa->setPoint(3,1000,200);
    $pa->setPoint(4,500,800);
    $pa->setPoint(5,0,0);

  # --- load the points into the polygon
  $cp->setPoints($pa);
  $cp->show();

  # --------------
  $canvas->update();
(..)


No error, nice filling pattern but no border.

	Thanks,

	Alain
