[Qgis-developer] SIGNAL to know when a feature is added to vector layer using PyQGIS

[Matthias Kuhn]

Hi Germán,

I don't think there's a signal to do that.

Is there a reason you have to write the the dataprovider directly rather
then using the layer's methods?
If you are in control of the code writing to the dataprovider and the
code that should react to this, you could also produce the signalling on
your side.
