Labeling features

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

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

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 = "/Users/joellawhead/qgis_data/ms/MSCities_Geo_Pts.shp"
  2. Next, we'll load the layer:

    lyr = QgsVectorLayer(src, "Museums", "ogr")
  3. Then, we'll create the labeling object:

    label = QgsPalLayerSettings()
  4. Now, we'll configure the labels, starting with the current layer settings being read:

    label.enabled = True
  5. Then, we specify the attribute for the...
