Ah, a very good idea. I got custom classes to work, but had to create an intermediate subclass of QWidget to do it:

class Stylesheeter(QWidget):
    def paintEvent(self, event):
        opt = QStyleOption()
	opt.initFrom(self)
        painter = QPainter(self)
        self.style().drawPrimitive(QStyle.PE_Widget, opt, painter, self)

no, just normal styling.
