Creating a GenGIS plugin

The functionality of GenGIS can be extended by writing a Python plugin. Python plugins reside in the plugins folder within your GenGIS directory. In this tutorial we will create a simple "Hello World" plugin which writes a simple greeting to the GenGIS viewport.

Required Files

Begin by creating the directory HelloWorld within the GenGIS plugins' directory. Within this directory create a file called __init__.py. This file contains general information about your plugin which is used by GenGIS to load the plugin. For our Hello World plugin, enter the following into __init__.py:

 def name():
   return "Hello World"

 def version():
   return "Version 1.0"

 def description():
   return "Prints Hello World to the Viewport."

 def authors():
   return "Donovan Parks"

 def publicationDate():
   return "March 1, 2012"

 def minimumVersionOfGenGIS(): 
   return "2.0"

 def requireR():
   return False
