QGIS Python Programming Cookbook - Second Edition

Labeling a feature

Once your map layers are styled, the next step to creating a complete map is labeling features. We'll explore the basics of labeling in this recipe.

Getting ready

Download the following zipped shapefile from https://github.com/GeospatialPython/Learn/raw/master/MSCities_Geo_Pts.zip.

Extract the shapefile to a directory named ms in your qgis_datadirectory.

How to do it...

We will load the point shapefile layer, create a label object, set its properties, apply it to the layer, and then add the layer to the map. To do this, we need to perform the following steps:

1. First, to save space, we'll specify the path to the shapefile:

           src = "/qgis_data/ms/MSCities_Geo_Pts.shp" 
   

2. Next, we'll load the layer:

    lyr = QgsVectorLayer(src, "Cities", "ogr") ...
