PySide: QVBoxLayout with QScrollArea

Here is an example that adds Scrollbars to a QVBoxLayout. The one thing that tripped me up was that you need to explicitly create a Widget for the QScrollArea.

import sys
from PySide.QtCore import *
from PySide.QtGui import *

class Widget(QWidget):

    def __init__(self, parent= None):
        super(Widget, self).__init__()
        self.setFixedHeight(200)

        #Container Widget
        widget = QWidget()
        #Layout of Container Widget
        layout = QVBoxLayout(self)
        for _ in range(20):
            btn = QPushButton("test")
            layout.addWidget(btn)
        widget.setLayout(layout)

        #Scroll Area Properties
        scroll = QScrollArea()
        scroll.setVerticalScrollBarPolicy(Qt.ScrollBarAlwaysOn)
        scroll.setHorizontalScrollBarPolicy(Qt.ScrollBarAlwaysOff)
        scroll.setWidgetResizable(False)
        scroll.setWidget(widget)

        #Scroll Area Layer add
        vLayout = QVBoxLayout(self)
        vLayout.addWidget(scroll)
        self.setLayout(vLayout)

if __name__ == '__main__':
    app = QApplication(sys.argv)

    dialog = Widget()
    dialog.show()

    app.exec_()
