QListWidget adjust size to content

Question

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_())

sizeHint() always returns 256, 192 no matter what its content is.

Thats because this is the size of the QListWidget, the viewport, not the items. sizeHintForColumn() will give you the max size over all items, so you can resize the widget like this:

list.setMinimumWidth(list.sizeHintForColumn(0))

If you don't want to force minimum width, then subclass and provide this as the size hint instead. E.g.:

class ListWidget(QListWidget):
  def sizeHint(self):
    s = QSize()
    s.setHeight(super(ListWidget,self).sizeHint().height())
    s.setWidth(self.sizeHintForColumn(0))
    return s
