QGIS » QGIS Application

User Feedback¶

I ran the following Python script and QGIS crashed:

from qgis.core import *
import processing

1. supply path to qgis install location
   QgsApplication.setPrefixPath("C:/Program Files/QGIS 3.4", True)

1. create a reference to the QgsApplication
2. setting the second argument to True enables the GUI, which we need
3. to do since this is a custom application

qgs = QgsApplication([], True)

1. load providers
   qgs.initQgis()

1. Write your code here to load some layers, use processing
2. algorithms, etc.

1. load layers
   iface.addVectorLayer("J:/GIS/Projects/TCARTA/00_CandidatePack/London_Major_roads_6m_buffer_32631.shp","Roads","ogr")
   iface.addVectorLayer("J:/GIS/Projects/TCARTA/00_CandidatePack/input/London_Moving_Vehicles_Image1_32631.shp", "Moving_Vehicles_Image1", "ogr")
   iface.addVectorLayer("J:/GIS/Projects/TCARTA/00_CandidatePack/input/London_Moving_Vehicles_Image2_32631.shp", "Moving_Vehicles_Image2", "ogr")
   iface.addVectorLayer("J:/GIS/Projects/TCARTA/00_CandidatePack/input/London_Static_Vehicles_Image1_32631.shp", "Static_Vehicles_Image1", "ogr")
   iface.addVectorLayer("J:/GIS/Projects/TCARTA/00_CandidatePack/input/London_Static_Vehicles_Image2_32631.shp", "Static_Vehicles_Image2", "ogr")

1. When your script is complete, call exitQgis() to remove the
2. provider and layer registries from memory
   qgs.exitQgis()
