I'm going to know how I can get layers full path in table of contents in QGIS3.4 when my QGIS is closed and it's running such as daemon?

Rememebr: my shapefiles are in some different folders.

enter image description here

This below is my code:

# If you are not inside a QGIS console you first need to import
# qgis and PyQt classes you will use in this script as shown below:
from qgis.core import *
import os
#This is is needed in the pyqgis console also
from qgis.core import (
QgsApplication.setPrefixPath("/usr", True)
# Create a reference to the QgsApplication. Setting the
# second argument to False disables the GUI.
qgs = QgsApplication([], False)
layersName =[]

# Get the project instance
project = QgsProject.instance()


for Layers in QgsProject.instance().mapLayers().values():


path_to_shape_layers_in_toc =[]
for l in layersName:


vlayer = QgsVectorLayer(path_to_shape_layers_in_toc[2],"Countour Layers","ogr")

if not vlayer.isValid():
    print("Layers not loaded!")

I expect exact path shown in properties window for each layers in TOC, but with this code I get only layers path loaded in TOC, not full path.

  • If you already have a QgsMapLayer (e.g., a QgsVectorLayer), use the source method: my_layer.source() to get the path of your layers or the connection string, if it's a layer coming from a DB. Sep 7, 2019 at 13:36
  • Actually I didn't find a solution in QGIS 3.x documents and developer cookbook also
