Understanding QPainterPath::simplified()

[Kryzon]

Hello.
My implementation of 'paintEvent' is giving a particular result:

void Widget::paintEvent( QPaintEvent * event )
{
	QPainter p ( this );
	p.setPen( QPen( QBrush( Qt::darkRed ), 2 ) );
	p.setBrush( QBrush( Qt::gray ) );
 
	QPainterPath myPath;
	myPath.moveTo( 600.0, 250.0 );
	myPath.cubicTo( 90.0, 50.0, 0.0, 50.0, 50.0, 370.0 );
	myPath.cubicTo( 140.0, 20.0, 10.0, 10.0, 600.0, 250.0 );
 
	myPath.addRect( 10.0, 300.0, 160.0, 34.0 );
 
	QPainterPath result ( myPath.simplified() );
	p.drawPath( result );
}

void Widget::paintEvent( QPaintEvent * event )
{
	QPainter p ( this );
	p.setPen( QPen( QBrush( Qt::darkRed ), 2 ) );
	p.setBrush( QBrush( Qt::gray ) );
	   
	QPainterPath myPath;
	myPath.moveTo( 600.0, 250.0 );
	myPath.cubicTo( 90.0, 50.0, 0.0, 50.0, 50.0, 370.0 );
	myPath.cubicTo( 140.0, 20.0, 10.0, 10.0, 600.0, 250.0 );
	
	myPath.addRect( 10.0, 300.0, 160.0, 34.0 );
		   
	QPainterPath result ( myPath.simplified() );
	p.drawPath( result );
}

Looking like this:


Shouldn't the intersected region between the rectangle and the bezier path be filled in the path generated by the 'simplified' call?
