Then you have the inverse problem:

----------------------------------------------
from qt import *

app = QApplication([])
sv = QScrollView(None)
w = QWidget(sv.viewport())

p = w.parent()
print sv.viewport().width()
----------------------------------------------
Traceback (most recent call last):
  File "D:\Work\caligola3d\src\pyqtbug3.py", line 9, in ?
    print sv.viewport().width()
AttributeError: width

which is wrong because viewport() is supposed to return a QWidget pointer.

[Yes, the type of that widget is an internal Qt's class]
