Setting font has no effect in QGraphicsItem subclass paint() method

[philw]

My custom drawing of a QGraphicsItem includes text using user-configurable fonts (previously picked with QFontDialog).

Attempting to assign the font to either the provided QPainter OR to the QGraphicsScene within my subclass’ QGaphicsItem::paint() method has no effect. The plan is to render a few different text pieces using distinct fonts. Is it possible to do this in QGraphicsItem::paint()? (virtual method override). [See code excerpt below].

I know I could deploy child QGraphicsTextItems or QGraphicsSimpleTextItems. I will if I have to. (Do I have to?).

(We're using Qt 4.8.5 on Windows).

QFont _labelFont;
const QString labelFontStr = labelFontName();
_labelFont.fromString (labelFontStr);
 
// virtual from QGraphicsItem
void TeacupGfxItem::paint (QPainter* painter, 
                           const QStyleOptionGraphicsItem* /*options*/,
                           QWidget* /*widget*/ /*=NULL*/)
{
   // ... ... ...
 
   // *** NEITHER OF THESE HAVE ANY EFFECT ***
   painter->setFont (_labelFont);
   scene()->setFont (_labelFont);
 
   const QString labelStr = teacupLabelStr();
   static const int textFlags = Qt::AlignHCenter | Qt::AlignTop  |
                                Qt::TextDontClip | Qt::TextSingleLine;
   QRectF drawnBoundRect; 
   painter->setPen (QPen (Qt::black));
   painter->drawText (_labelRect, textFlags, labelStr, &drawnBoundRect);
}

QFont _labelFont;
const QString labelFontStr = labelFontName();
_labelFont.fromString (labelFontStr);

// virtual from QGraphicsItem
void TeacupGfxItem::paint (QPainter* painter, 
                           const QStyleOptionGraphicsItem* /*options*/,
                           QWidget* /*widget*/ /*=NULL*/)
{
   // ... ... ...

   // *** NEITHER OF THESE HAVE ANY EFFECT ***
   painter->setFont (_labelFont);
   scene()->setFont (_labelFont);
   
   const QString labelStr = teacupLabelStr();
   static const int textFlags = Qt::AlignHCenter | Qt::AlignTop  |
                                Qt::TextDontClip | Qt::TextSingleLine;
   QRectF drawnBoundRect; 
   painter->setPen (QPen (Qt::black));
   painter->drawText (_labelRect, textFlags, labelStr, &drawnBoundRect);
}
