For those that are interested, or Qt beginners like me: by examining Qt C++
source code, I have finally found a solution: I have specialized paintEvent
in my QComboBox derived class. For example, if I want to print "toutou" in
my QComboBox, I modify the QStyleOptionComboBox in paintEvent:

    def paintEvent( self, qpaintevent ):

        painter = QStylePainter( self )
        painter.setPen( self.palette().color( QPalette.Text ) )

        # draw the combobox frame, focusrect and selected etc.
        opt = QStyleOptionComboBox()
        self.initStyleOption( opt )
        opt.currentText = QString( "toutou" ) # HERE!!!!!!
        painter.drawComplexControl( QStyle.CC_ComboBox, opt )

        # draw the icon and text
        painter.drawControl( QStyle.CE_ComboBoxLabel, opt)


I have just translated paintEvent from C++ to Python, and add the
line "opt.currentText = QString( "toutou" )" to modify the content of the
QComboBox once one item has been chosen by the user.

Thanks

Julien
