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

[karsten vennemann]

Maybe I shoud clarify this more
Right now this works:  I can send the signal and have the value of the combox be used to update a field in the attribute table , 
however in addition I would like to add the id of the combobox that I can determine which column should be updated in the changeValue function
How can this be done ?
