Function arguments - how to get a reference

[caduel]

those function more often use const references...
for const references you can just pass the (temporary) value:

QRectF rect=...;
QPointF pt=...;
QGraphicsItem *item=...;
rect.contains(item->mapToScene(pt));

QRectF rect=...;
QPointF pt=...;
QGraphicsItem *item=...;
rect.contains(item->mapToScene(pt));

To copy to clipboard, switch view to plain text mode 

You can't do that for non-const references, though.
