13# Common definitions and utilities for the GUI
14#
15# The main purpose of this module is to provide common definitions for things
16# that are named differently in Gtk+ 2 and 3. This way the other parts of the
17# GUI have to check the version in use very rarely. The variable \ref pygobject
18# tells which version is being used. If it is \c True, Gtk+ 3 is used via the
19# PyGObject interface. Otherwise Gtk+ 2 is used, which is the default on
20# Windows or when the \c FORCE_PYGTK environment variable is set.
21#
[302]22# Besides this there are some common utility classes and functions.
