# [June 2011]
# For now, we do not force the QString, QVariant, (...) API number because
# `guidata` and its visualization counterpart `guiqwt` are compatible
# with both API #1 and API #2. Moreover, `guiqwt` is currently based on
# PyQwt, so unless we switch to Python 3 (probably not until 2012-2013),
# there is absolutely no point forcing API to #2 because it wouldn't work
# with PySide anyway (because a PySideQwt library would be needed).
# But note that `guidata` itself already works with PySide (a few things
# need to be done to officially support PySide, like the file dialogs
# compatibility issues).
#
# As a consequence, with Python 2.x, the default PyQt API will be API #1
# (i.e. with QString and QVariant objects), unless the API has been set
# before importing this module.
