QListWidget adjust size to content

Is it possible to adjust QListWidget height and width to it's content?

sizeHint() always returns 256, 192 no matter what its content is.
QListWidgetItem's sizeHint() returns -1, -1, so I can not get content width.

Problem the same as here - http://www.qtcentre.org/threads/31787-QListWidget-width , but there is no solution.

import sys
from PyQt4.QtGui import *

class MainWindow(QWidget):
    def __init__(self, parent=None):
        QWidget.__init__(self, parent)

        list = QListWidget()
        list.addItem('111111111111111')

        vbox = QVBoxLayout(self)
        vbox.addWidget(list)

app = QApplication(sys.argv)
myapp = MainWindow()
myapp.show()
sys.exit(app.exec_())
