15# Common definitions and utilities for the GUI
16#
17# The main purpose of this module is to provide common definitions for things
18# that are named differently in Gtk+ 2 and 3. This way the other parts of the
19# GUI have to check the version in use very rarely. The variable \c pygobject
20# tells which version is being used. If it is \c True, Gtk+ 3 is used via the
21# PyGObject interface. Otherwise Gtk+ 2 is used, which is the default on
22# Windows or when the \c FORCE_PYGTK environment variable is set.
23#
24# Besides this there are some common utility classes and functions.
