Introduction

Before using this tutorial

Prior to working through this tutorial, it is recommended that you have a reasonable grasp of the Python programming language. GUI programming introduces new challenges compared to interacting with the command line. It is necessary for you to know how to create and run Python files, understand basic interpreter errors and warnings, work with strings, integers, floats, and Booleans. For the advanced widgets covered in this tutorial, good knowledge of lists and tuples will also be required.

Prior knowledge of GTK+ is not required.

About this tutorial

This guide assumes that you are using the Python 3.4 series and that you are using GTK+ 3.16 and an as-up-to-date version of Python-GObject as possible. The newer the Python-GObject version, the less likely there are to be issues. Older versions will work for some examples.

To see which version of GTK+ you have installed, run the following script to check the verison number.

Deprecation

Deprecation is the process of preparing features within software to be decommisioned and removed. GTK+ deprecates objects by providing warnings both in the GTK+ framework and documentation prior to removal at a later date. This allows developers to change their code before a feature is removed. In many cases however, a feature is not removed until the next major release to prevent mass breakage of applications.

Reasons for deprecation generally include a feature being superseded, or a feature no longer being widely used.

It is highly recommended to not use deprecated features of GTK+ or Python when developing applications, particularly when learning as they can cause problems when understanding other areas of development.

This tutorial does not cover widgets which have been marked as deprecated. Any widgets marked as deprecated by GTK+ in the future will also be removed from future versions of the tutorial.
