[Qgis-developer] PyQT - How to get layer sending attributeValueChanged signal?

[Matthias Kuhn]

Hi Régis

Calling sender() in your SLOT should return the QgsVectorLayer object
There is also QSignalMapper [1] which has a cleaner concept, but it 
looks as if this will on the one hand help you to identify the source 
layer, but you will loose any other parameters, what's probably not 
your intent.
