Hi my question is related to this: PyQT4 WheelEvent

from PyQt4.QtGui import *
from PyQt4.QtCore import *

import sys


class Main(QWidget):
    def __init__(self, parent=None):
        super(Main, self).__init__(parent)

        layout = QHBoxLayout(self)
        layout.addWidget(Scroll(self))


class Scroll(QScrollArea):

    def __init__(self, parent=None):
        super(Scroll, self).__init__(parent)
        self.parent = parent

    def wheelEvent(self, event):
        super(Scroll, self).wheelEvent(event)
        print "wheelEvent", event.delta()

        newHeight = self.parent.geometry().height() - event.delta()
        width     = self.parent.geometry().width()
        self.parent.resize(width, newHeight)

app = QApplication(sys.argv)
main = Main()
main.show()
sys.exit(app.exec_())

My Scroll class is created in Qt Designer and i have no access to it Is there any opportunity to have access to PyQT WheelEvent of Scroll class but in Main class?
