[Qgis-developer] PyQt VectorLayer signal

[Matthias Kuhn]

Hi Bernhard,

I stumbled upon this also today.

It seems, that this signal is emitted nowhere, while the same signal is 
emitted by the edit buffer behind the vector layer.
While something like connecting your slot every time layer editing is 
started (needed, because the edit buffer gets deleted/created based on 
editing state) or connecting to featureAdded, which is also emitted may 
work, I've just issued a pull request to fix this [1].

Cheers,
Matthias
