Quoting "Fredrik Corneliusson" <[email protected]>:
I'm localizing a PyGTK application (win32 & py2exe).
As my target audience is multilingual and might not want to have the
user interface language set to the system default I have made it
configurable.
This works for the custom strings in my application but not for the
built in GTK messages. You can change the locale by setting the LANG
environment variable manually _before_ starting the application but
that is sub optimal as the user selected locale is stored in a config
file in users settings directory.
Setting the environment variable after Python has started has no
effect on GTK (even if I do it before loading any GTK modules).
Starting with Python 2.4, changing os.environ only changes the copy of
the environment variables for Python. Processes on windows can have multiple
copies of the environment variables. In the case of a pygtk application
there's another copy maintained by the OS, one maintained by msvcr90 (the C
runtime used by Python) and depending on how your gtk+ runtime was built
there may be a copy for msvcrt (as is the case if you're using the binaries
from ftp.gnome.org). Thus you need to update all 4 copies for things to work.
I've written a module that solves the madness, you can find it on
https://github.com/dieterv/elib.intl/ (you'll need to clone the code,
there are no downloadable packages yet...)
Read the inline docstrings of the install() and install_module() functions
to learn how to use elib.intl and the docstring of the _getscreenlanguage()
function to learn how the language to use is determined. Hint, we don't
look at the keyboard language but the actual screen language in use. Using
the keyboard language is a common error you'll see in a lot of other
software packages ported to windows that use gettext...
mvg,
Dieter
