How can my program have 2 languages?
-
Ok, it looks like an "Installation and Deployment" problem...
In linux directories used for configuration files are:
/etc/program and /home/user_name/.program and /usr/share/program/Due to linux file system standards I suggest put your translation files in /usr/share/program/translations.

[quote author="Leon" date="1309285305"]The translations at /usr/share/program/translations must be at .ts format or .qm format?[/quote]
You need only qm files in runtime. ts files are used to translate. at runtime you want to load translated data.
Also notice that there is no magic with /usr/share/program/translations. that was just a suggestion. you could put your translations in every other location... -
I am thinking of having english greek dutch and french language at my program.. Should i have a combobox with this 4 languages only ( using the resource file) or should i check for file existences at the path that i have my translations and then add them to the combobox?

Hello again! What do you suggest? After the language has been changed ( at a combobox probably ) instantly everything change to the language you selected with "this way":http://developer.qt.nokia.com/faq/answer/how_can_i_dynamically_switch_between_languages_in_my_application_using_e.g_ or change the language after you restart the application?

What I did was this:
1- Create a proxy subclass of QDialog named ProxyDialog wich have only one method: retranslateUI()
2- Subclass all dialogs from ProxyDialog
3- When you need to translate UI, just iterate over children of type ProxyDialog* and call retranslate UI for all of them. this is possible using findChildren function. -
Yes. I'm not sure if there is a better way or not, but I looked around a lot and couldn't fount anything.
This works well for my applications.
You don't have to restart your application to see translation results. All open dialogs will be translated on-the-fly.
