[maemo-developers] How to make a finger scrollable frame for widgets in Qt 4.5?

[From: Luca Donaggio]

This is an example in python using PySide bindings dor Qt4.6:

from PySide.QtCore import *
from PySide.QtGui import *
from PySide.QtMaemo5 import *
import sys

class StackedWindow(QMainWindow):
    def __init__(self):
        QMainWindow.__init__(self)
        # This attribute makes the whole Stacked Window thing work
        self.setAttribute(Qt.WA_Maemo5StackedWindow)
        # Create button and layout
        self.cw = QWidget(self)
        # This is ugly, but otherwise widgets don't horizontally expand
inside the ScrollArea
        self.cw.setMinimumSize(800,0)
        self.vbox = QVBoxLayout(self.cw)
        self.button = QMaemo5ValueButton(self)
        self.button.setText(QString('Push me'))
        self.button.setValueText(QString('I told you to push me!'))
        self.vbox.addWidget(self.button)
        self.label = QLabel(self)

self.label.setText(QString('Long\nmultiline\nlabel.\n\n\n\n\nVeeery\nlong\nand\nvery\nmultiline\nlabel!'))
        self.vbox.addWidget(self.label)
        self.vbox.setSizeConstraint(QLayout.SetMinAndMaxSize)
        #Create a ScrollArea and put the container widget inside
        self.sa = QScrollArea(self)
        self.sa.setWidget(self.cw)
        self.setCentralWidget(self.sa)
        # Connect button to signal
        self.connect(self.button, SIGNAL("clicked()"), self.openSubWin)

    def openSubWin(self):
        # Create subwindow
        self.subWindow = SubWindow(self)
        self.subWindow.show()

class SubWindow(QMainWindow):
    def __init__(self, parent):
        # Notice that you must give a parent window as parameter to the
constuctor
        QMainWindow.__init__(self, parent)
        # Also set the Stacked Window parameter for every subwindow in the
stack
        self.setAttribute(Qt.WA_Maemo5StackedWindow)
        # Just some content...
        self.label = QLabel(self)
        self.label.setText(QString("This is a second window in the stack"))
        self.setCentralWidget(self.label)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    sw = StackedWindow()
    sw.show()
    sys.exit(app.exec_())
