[Qgis-developer] pyQT combo box & QGIS plug-in signal argument question

[karsten vennemann]

Hi all,
 
in a python QGIS plug-in I have a form with a dynamically generated pyQT combo box. 
Now I am trying to have a change in the combo box send a signal with one argument (which is the id of combo box) to the called function changeValue. Note this changes the attribute of one field in a shape file attribute table and I need the combo box id to know which field will be changed by the changeValue function). How can I do this ?
So far I have.
 
 QObject.connect(comboBoxNew[dropbox_counter],SIGNAL("currentIndexChanged(QString)"),self.changeValue)

    def changeValue(self, value):
        mc = self.canvas         
        layer = mc.currentLayer()
        ob = layer.selectedFeaturesIds()
        layer.changeAttributeValue(int(ob[0]),self.id(),value)

Thanks for any hints as I have been  stuck with this for days ;)

Cheers
