Description
Hello, I tried to follow this article :
http://anitagraser.com/2014/04/26/getting-started-writing-qgis-2-x-plugins/
and met a problem when I “reloaded” my plugin “plop” in Qgis :
“Une erreur est apparue lors de l’exécution du code Python :
Traceback (most recent call last):
File “C:/Users/Utilisateur/.qgis2/python/plugins\\plop\\plop.py”, line 186, in run
layers = QgsMapLayerRegistry.instance().mapLayers().values()
NameError: global name ‘QgsMapLayerRegistry’ is not defined
Version de Python :
2.7.5 (default, May 15 2013, 22:44:16) [MSC v.1500 64 bit (AMD64)]
Version de QGIS :
2.4.0-Chugiak Chugiak, 8fdd08a”
I tried to declare QgsMapLayerRegistry at the beggining of “plop.py” withy from PyQt4 import QgsMapLayerRegistry, but it’s say “cannot import name QgsMapLayerRegistry”
What is the problem ?
Thank you !!!

You need to :
from qgis.core import QgsMapLayerRegistry
In breif, when your object start with Qgs*, it comes from the qgis package, not from the PyQt4.
