QMenu Icon Scale in PyQt?

Several postings about setting the QMenu Icon size to be larger then the defaulted 16x16 have been reviewed:

http://www.qtcentre.org/threads/1574...-size-in-QMenu
http://www.qtcentre.org/threads/4173...r-resize-icons

Yet I am unable to establish how exactly to implement what these postings have deemed successful in context of PyQt.
Currently my menu is created via the following code:

Code:

# build the CSV option Menu
        self.CSVoptionMenu = QMenu( self.iface.mainWindow() )
        for Option in CSVOptionList:
            self.CSVoptionMenu.addAction(Option)
        self.CSVoptionMenu.setLayoutDirection(QtCore.Qt.LeftToRight)
        self.CSVoptionMenu.setStyleSheet('QMenu::item {padding: 4px 6px 4px 6px;}  QMenu::item:selected\
                                        {color: white; background-color:  QLinearGradient( x1: 0, y1: \
                                        0, x2: 0, y2: 1, stop: 0 #49a4ff, stop: 1 #1e84ea);}')
        self.CSVoptionMenu.setIcon(QIcon(":/plugins/graphicgroundwater/buttons/optionsCSVedit.png"))
        self.CSVoptionMenu.setTitle("Edit Options")
        self.CSVoptionMenu.triggered.connect(self.runOptionCSVEditor)

I supposed it might be as simple as appending a string to the 'setStyleSheet()' command, but after several attempts with no success - I figured someone might have clearer insights on the issue.
