How to make QWidget contents scrollable in PyQt?

Question

First, I started using PyQt few hours ago. So far so good - im writing rss client to familiarize myself with PyQt I got QApplication, QMainWindow and two custom widgets. First custom widget is:

class RssItem(QWidget):
    __pyqtSignals__ = ("articleViewed(bool)",
                       "articleOpened(bool)",
                       "articleMarkedGood(bool)")

    def __init__(self, title, date, parent = None):
        super(RssItem, self).__init__(parent)
        self.initWidget(title, date)

    def initWidget(self, title, date):
        title = QLabel(title)
        date = QLabel(date)
        titleBox = QHBoxLayout()
        titleBox.addWidget(title)
        titleBox.addWidget(date)
        self.setLayout(titleBox)

That displays (for now) title and date in single row Second one accepts array of RssItem widgets and display them in vertical list:

class ItemsList(QWidget):
    def __init__(self, items, parent=None):
        super(ItemsList, self).__init__(parent)
        self.initWidget(items)

    def initWidget(self, items):
        listBox = QVBoxLayout(self)
        for item in items:
            listBox.addWidget(item)
            listBox.addStretch(1)
        self.setLayout(listBox)

How do I make this list scrollable? Keep in mid I'm planing to have multiple ItemList's in one window each should have it's own scrollbar.

Main app function as for now is only for testing these 2 widgets:

class MainApp(Qt.QApplication):
    def __init__(self, args):
        super(MainApp, self).__init__(args)
        self.addWidgets()
        self.exec_()

    def addWidgets(self):
        self.window = MainWindow()


class MainWindow(QtGui.QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()
        self.initUI()

    def initUI(self):
        self.statusBar().showMessage("ok")
        self.resize(640, 480)
        self.setWindowTitle("Smart Rss")
        items=[]
        for x in range(0, 200):
            items.append(RssItem("Title no %s" % x, "2000-1-%s" %x))
        self.setCentralWidget(ItemsList(items))
        self.show()

EDIT:Getting closer, changed ItemList.initWidget to

def initWidget(self, items):
    scroll= QScrollArea(self)
    wrap = QWidget(self)
    listBox = QVBoxLayout(self)
    for item in items:
        listBox.addWidget(item)
        listBox.addStretch(1)
    wrap.setLayout(listBox)
    scroll.setWidget(wrap)

But now I cant figure out how to make QScrollArea fill all available space and auto resize when it's changed.

Try scroll.setWidgetResizable(True) like in here:

def initWidget(self, items):
    listBox = QVBoxLayout(self)
    self.setLayout(listBox)

    scroll = QScrollArea(self)
    listBox.addWidget(scroll)
    scroll.setWidgetResizable(True)
    scrollContent = QWidget(scroll)

    scrollLayout = QVBoxLayout(scrollContent)
    scrollContent.setLayout(scrollLayout)
    for item in items:
        scrollLayout.addWidget(item)
    scroll.setWidget(scrollContent)
