Re: How to create a simple multilingual GUI
Ooop, took wrong file. It's hello_intl-0.1.tar.gz which is the GTK app, not gettext-0.16 (gettext tarball). :/ = I finally managed to make a dynamically language-changing console app. However, I'm still trying to understand how to correctly use gettext with Anjuta+Glade. Here is my source code for my apps, as well as .mo files I took from the gettext tarball. How should I proceed to use .mo files with a GTK app created using the Anjuta+Glade combo? I tried placing .po files (created from the Anjuta generated .pot template) in the po directory and adding a LINGUAS file with the available languages, but it didn't work.

Re: How to create a simple multilingual GUI
Well, it's possible to change the language in Firefox and in a lot of other programs. I don't mind having to restart the program to do it. I just don't want to have to change the system's local language to do it. I know that gettext is mostly used for internationalisation. However, I have problems creating a program with it where I choose the language in the program, independently of the system settings. If somebody knows how to do this, I would be really grateful for a simple example program, even if it's only command-line and without a GUI. In the meanwhile, I began looking at the source code of tuxtyping, where changing the language at runtime is possible.

That does not make it a good idea.
Firefox is designed for Microsoft Windows -- where one had
to reinstall the system it to switch languages. Applications
tried to work around it and each invented its own language
switching mechanism.
We've had a standard mechanism since ever. All programs
that support localization respect -- or should respect
-- language preferences expressed with locale variables.
Running
LC_ALL=cs_CZ app
should run app in Czech. By editing the command used to
run the application this should be relatively easy to do
with a GUI launcher too -- in fact, the launcher editors in
desktop environments should offer the possibility to set the
language for individual applications to make it easier.
What we don't need is every program inventing its own
method to express language preferences.
I don't mind having to restart the program to do it.
With restarting it is easy. The only thing you need to do
is to set locale to the desired one on startup, overriding
what you have inherited from environment. See below.
I just don't want to have to change the system's local language to do it.
What is `the system local language'? Probably there's no
such thing and therefore you cannot change it. You can set
locale [categories] for each program individually (several
possibilities have been listed), and that's what you also
should do.
I know that gettext is mostly used for internationalisation. However, I have
problems creating a program with it where I choose the language in the
program, independently of the system settings.
Call setlocale() or set LC_* environment variables as
suggested, each process has its own. And you should use the
inherited locale as the default.
If somebody knows how to do this, I would be really grateful for a simple
example program, even if it's only command-line and without a GUI.
=
#include stdio.h
#include time.h
#include locale.h
int
main(int argc, char *argv[])
{
time_t t;
char s[1024];
if (argc 1)
setlocale(LC_ALL, argv[1]);
time(t);
strftime(s, sizeof(s), %c, localtime(t));
printf(%s\n, s);
return 0;
}
=
Pass it a locale name and it will print the current date and
time in the form preferred for that locale (i.e. language
+ region) because %c means locale-defined date and time
format. Observe it leaves your system local language
(whatever it is) intact.
Everything else (e.g. adding gettext which is controlled by
the same variables or storing the selected language in
some preferences file) is a straighforward extension.
In the meanwhile, I began looking at the source code of tuxtyping, where
changing the language at runtime is possible.
But having a clear simple source code for something like that really makes
it easier.
It is a lot easier if your user interface is a set of
independent screens, exactly one active at any time. When
you switch languages, you just discard the current screen
and construct it again. This is not how a typical Gtk+
application looks like though.

You have to keep all your user-string-displaying widgets in a list, and set the label/text for each of them every time the language changes, and after notifying gettext of the change. If the languages differ in the direction of reading (LTR-RTL), more has to be done. Calling gtk_widget_set_default_direction() with the direction obtained from _(default:LTR) will generally take care of it, though corner cases can remain. Also labels (and input widgets) possibly containing numbers or date time have to be rendered again, regettexting is not everything. And there are other regional settings you either have to deal with or it's unclear what to do with upon a switch. So, impossible is probably a too strong word but maintenance nightmare it definitely is.

This can quickly turn into a nightmare, because the width of labels tends to change from language to language, and non-resizable windows will not re-shrink after a verbose language. I seem to remember that Ubuntu's installer Ubiquity has dynamically switches the language on the first page of installation (with a list of languages on the left, and clicking on one of these languages changes the UI translations at runtime). You might want to check the Ubiquity code to see how they do this?
