Creating HTML labels in QGIS

QGIS map tips allow you to hover the mouse cursor over a feature in order to create a popup that displays information. This information is normally a data field, but you can also display other types of information using a subset of HTML tags. In this recipe, we'll create an HTML map tip that displays a Google Street View image at the feature's location.

Getting ready

In your qgis_data directory, create a directory named tmp.

You will also need to download the following zipped shapefile and place it in your qgis_data/nyc directory:

How to do it...

We will create a function to process the Google data and register it as a QGIS function. Then, we'll load the layer and set its map tip display field. To do this, we need to perform the following steps:

1. First, we need to import the Python libraries we'll need:

   from qgis.utils import qgsfunction
   from qgis.core import QGis
   import urllib  ...
