QTextLayout draws text outside the widget

Hi all,

Working on simple CAD application using QGraphicsView/QGraphicsScene, I'm trying to implement a 'text entity' derived from QGraphicsItem. (something like the QGraphicsSimpleTextItem).
Inside this item I'm using the QTextLayout::draw() to draw the text. And this is the problem. The text is drawn also outside the view widget (QGraphicsView) as shows the attached image.

Has anybody an idea how to solve this? I can also post a code ...
Thans a lot

WTF? Wow, what have you done to achieve that? :D

That would be the easiest way, because I can imagine some errors...

yeah, it's pretty strange :)

here's the code:

/**

void CTextItem::paint(QPainter* painter, const QStyleOptionGraphicsItem* option, QWidget* widget)
{
	if (isSelected())
		painter->setPen(_sel_pen);
	else
		painter->setPen(_std_pen);
 
 
	_layout->draw(painter, QPointF(0, -_line_height));
 
 
	// draw cursor
	if (_draw_cursor)
	{
		painter->setPen(_cur_pen);
		painter->drawLine(_lastline_width, boundingRect().bottom(), _lastline_width + Lexo2D::Const::DEFAULT_TEXT_SIZE, boundingRect().bottom());
	}
 
 
	// for debugging purposes ... 
	if (Lexo2D::Debug::show_bounding_rectangles)
	{
		// draw bounding rectangle
		painter->setPen(QColor(255, 0, 0));
		painter->drawRect(boundingRect());
 
		// draw shape
