how i can install python-qt4 to make this working?
===

I really want to use QUrl, but I can not do this after installation PyQt4 on my Ubuntu 10.04 via <i>$ sudo apt-get install python-qt4</i>

    Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41) 
    [GCC 4.4.3] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import PyQt4.QtCore
    >>> import PyQt4.QtCore as qq
    >>> dir(qq)

    >>> qq.__file__

'/usr/lib/pymodules/python2.6/PyQt4/QtCore.so'

    >>> from PyQt4.QtCore import QUrl

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name QUrl

What I should to do, to fix this ?

Thx.
