Adding QGraphicsDropShadowEffect to part of a "modified" QGraphicsPixmapItem?

Hi,

In my GUI application I show what i call ModelObjectGraphicsItem's in a QGraphicsView. An example is (hopefully) seen below:

(I try to attach the image file as well...)

However, I'd prefer not to drop shadow on the text labels but only on the "boxes". Any ideas on how I avoid this?

Here's an overview of my ModelObjectGraphicsItem class:

Code:

ModelObjectGraphicsItem::ModelObjectGraphicsItem(GraphicsScene* modelScene, ModelObject* modelObject) :
QGraphicsPixmapItem(*modelObject->pixmap(), 0, modelScene)
{
	modelObject_ = modelObject;
 
	QPoint& pos = modelObject_->position();
	pixmapSize_ = modelObject_->pixmap()->size();
 
	setPos(pos);
	originalOffset_ = pos;
 
	setZValue(1);
//	setTransformationMode(Qt::SmoothTransformation);
 
	selectionItem_ = new QGraphicsRectItem(
							pos.x() - 2, pos.y() - 2, pixmapSize_.width() + 4,
							pixmapSize_.height() + 4, 0, modelScene);
	selectionItem_->setVisible(false);
	QPen p(Qt::red);
	selectionItem_->setPen(p);
	selectionItem_->setZValue(5);
 
	QGraphicsDropShadowEffect* shadow = new QGraphicsDropShadowEffect();
	shadow->setOffset(QPointF(3, 3));
	setGraphicsEffect(shadow);
 
	labelMetrics_ = new QFontMetrics(QFont());
	labelWidth_ = 0;
	labelHeight_ = labelMetrics_->height();
	labelVisible_ = true;
 
	updateItem();
}

The text labels are drawn/shown as follows (the painter->drawText(...)):

Code:

void ModelObjectGraphicsItem::paint(QPainter* painter, const QStyleOptionGraphicsItem* option, QWidget* widget = 0)
{
	// Paint the pixmap item
	QGraphicsPixmapItem::paint(painter, option, widget);
 
	// Paint the label (if visible)
	QPoint labelPos((pixmapSize_.width() / 2) - (labelWidth_ / 2), pixmapSize_.height() + labelHeight_);
	if (labelVisible_)
		painter->drawText(labelPos, labelText_);
}

Any ideas on how I can "drop shadow" only from the "boxes"?
