# would first pass through the translation function and try to load a
# translated version of the string from the current message catalogs.
# For this example, since we are changinb language on the fly, and
# since we are only translating the label for one widget, we'll not do
# it the automatic way and we'll be more explicit. See the setup in
# __init__() and the translation done in updateLanguage() below.
