QGraphicsItem::itemChange() is the correct approach, you were probably just checking the wrong flag. Something like this should work fine:

QVariant::myGraphicsItem( GraphicsItemChange change, const QVariant &value )
{
  if( change == QGraphicsItem::ItemPositionHasChanged )
  {
     // ...
  }
}

Note the use of QGraphicsItem::ItemPositionHasChanged rather than QGraphicsItem::ItemPositionChange, the former is called after the position changes rather than before.
