translations.pri

# This include file makes generation and installation of .qm files
# from .ts files and updating .ts files from the sources easier.
#
# An application which has translations can use this include file as
# in the following example for “widgetsgallery”:
#
# Create a subdirectory “translations” in the source folder of the
# application which contains a translations.po file and the .ts
# files, for example if the source dir is “libm/demos/widgetsgallery”:
#
#    libm/demos/widgetsgallery/translations.pro
#    libm/demos/widgetsgallery/widgetsgallery_ar.ts
#    libm/demos/widgetsgallery/widgetsgallery_de.ts
#    libm/demos/widgetsgallery/widgetsgallery_en.ts
#    libm/demos/widgetsgallery/widgetsgallery_fi.ts
#
# The translations.pro file should have contents like this:
#
#    LANGUAGES = ar de en fi
#    CATALOGNAME = widgetsgallery
#    SOURCEDIR = $$PWD/..
#    TRANSLATIONDIR = $$PWD
#    MROOT = ../../..
#    include($$MROOT/mconfig.pri)
#    include($$MROOT/translations.pri)
#
# It is better to have an extra translations.pro file in the directory
# where the translations are instead of adding the stuff for the translations
# to the .pro file of the application (“widgetsgallery.pro”).
# It is possible to add similar stuff to update the .qm files
# directly to the application profile but the disadvantage is that
# changing the .ts files then causes the application to rebuild
# (because of qmake limitations).
#
# Introducing the extra translations/translations.pro file makes it
# necessary to add the widgetsgallery/translations directory to the
# list of sub-directories in a .pro file higher up in the directory
# hierarchy. For example the libm/demos/demos.pro file contains
# something like the following:
#
#    SUBDIRS     =  \
#        servicefw \
#        widgetsgallery \
#        widgetsgallery/translations \
#        animatedlayout \
#        animatedlayout/translations \
#        launcher \
#        qtstyleexample
