Basic Implementation of Scroll Area in PyQt4

PyQt4 / Python 3 / Windows 7

Hello -- I am fairly new to PyQt and I'm having a great deal of trouble figuring how out to implement a basic scroll area. Attached is some simple sample code - how can I set this window to scroll rather than extend the window below the screen edge? Thank you

@import sys
from PyQt4 import QtGui
from random import choice

class ThisWindow(QtGui.QWidget):
def init(self):
super(ThisWindow, self).init()
self.initUI()

def initUI(self):    
    vbox = QtGui.QVBoxLayout() 
          
    itemlist = GenerateList()        
    
    for item in itemlist:
        newlabel = QtGui.QLabel(item)
        newcheckbox = QtGui.QCheckBox()
        newcombobox = QtGui.QComboBox()
        
        new_row_box = QtGui.QHBoxLayout()
        
        new_row_box.addWidget(newlabel)
        new_row_box.addWidget(newcheckbox)
        new_row_box.addWidget(newcombobox)
        new_row_box.addStretch(1)
        
        vbox.addLayout(new_row_box)
        
    self.setGeometry(100,100,800,600)
    
    self.setLayout(vbox)    
    self.setWindowTitle('How do I make this window scroll if it gets beyond a certain height (e.g. the edge of the screen?)')    
    self.show()

def GenerateList():
itemlist = []
top = choice(range(50,150))
for x in range(0,top):
item = "Label # {0}".format(x)
itemlist.append(item)
return itemlist

def main():
app = QtGui.QApplication(sys.argv)
win = ThisWindow()
sys.exit(app.exec_())

if name == 'main':
main()@

The best way to do this is using QScrollArea as demonstrated below:

@
from PyQt4.QtGui import *
from random import choice

class ThisWidget(QWidget):
def init(self, parent=None):
QWidget.init(self, parent)

    l=QVBoxLayout(self)
    l.setContentsMargins(0,0,0,0)
    l.setSpacing(0)

    s=QScrollArea()
    l.addWidget(s)

    w=QWidget(self)        
    vbox=QVBoxLayout(w)

    for x in range(0, choice(range(50,150))):
        _l=QHBoxLayout()
        _l.addWidget(QLabel("Label # %d" % x, self))
        _l.addWidget(QCheckBox(self))
        _l.addWidget(QComboBox(self))
        _l.addStretch(1)
        vbox.addLayout(_l)

    s.setWidget(w)

    self.setGeometry(100, 100, 800, 600)
    self.setWindowTitle("This is how you make the window scroll if it gets beyond a certain height")

if name=="main":
from sys import argv, exit
a=QApplication(argv)
win=ThisWidget()
win.show()
win.raise_()
exit(a.exec_())
@

Hope this helps.
