How can my program have 2 languages?

[Leon]

Ok thanks guys.. I am working on it..

soroush i know it is a suggestion :P

The .qm files can also be included as resources, too.

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?

Second way sounds better - this allow your users adding new languages for your app without re-compilation.
of course if your public .ts file.

[Leon]

Yes but who would do that? I think i will go with the first one and if anyone translate my app i will add the language at another version.. :)

[Leon]

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.

[Leon]

So you suggest that i should translate everything instantly?

[soroush]

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.

Ok then, thanks again!
