It would have been helpful if you would have given slightly more 
context, but I will assume for now that you are refering to 
QGraphicsItem::setParentItem, as that seems to be the only function with 
that name in Qt.

Did you head the warning in the documentation?
 > Calling this function on an item that is an ancestor of parent have 
undefined behaviour.
