Thanks for all the input I received
I found one seemingly good solution (via internet search) that works using
functools.partial that is available since python 2.5
http://docs.python.org/library/functools.html#functools.partial
My code is then
...
from functools import partial
...
QObject.connect(comboBoxNew[dropbox_counter],SIGNAL("currentIndexChanged(QSt
ring)"),partial(self.changeValue, x = dropbox_counter))
def changeValue(self, value, x):
mc = self.canvas
layer = mc.currentLayer()
ob = layer.selectedFeaturesIds()
layer.changeAttributeValue(int(ob[0]),x,value)
Hopefully that helps someone else too when trying to easily pass an
additional parameter from an QT signal slot ...
