Bizarre static_cast trick?
- by Rob
While perusing the Qt source code I came across this gem:
template <class T> inline T qgraphicsitem_cast(const QGraphicsItem *item)
{
return int(static_cast<T>(0)->Type) == int(QGraphicsItem::Type)
|| (item && int(static_cast<T>(0)->Type) == item->type()) ? static_cast<T>(item) : 0;
}
Notice…
