I am trying to apply the style from .qml to a group of layers in QGIS. I have tried to incorporate LoadNamedStyle within jkall's code here: https://github.com/jkall/qgis-processing-scripts/blob/master/set_transparency_for_group.py I end up with this:

from qgis.core import *
def applystyle_group(name):
    root = QgsProject.instance().layerTreeRoot()
    point = root.findGroup(name) #Find Group AP
    for child in point.children():
        if isinstance(child, QgsLayerTreeLayer):
            if child.layer().type()==0:

It gives me an error:

Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "C:/OSGeo4W64/bin/applystyle_group.py", line 9, in <module>
  File "C:/OSGeo4W64/bin/applystyle_group.py", line 8, in applystyle_group
AttributeError: 'QgsLayerTreeLayer' object has no attribute 'loadNamedStyle'

Does QgsLayerTreeLayer have something similar to loadNamedStyle?


Change this line




Your child object is of type QgsLayerTreeLayer, but you need to access layer() to get its correspondent QgsMapLayer, which has a loadNamedStyle() method.
