one UI language, another internal Topic is solved

[mael15]

Hi everyone,
my program creates pdfs and shows a preview with a certain language. Now I want to change the UI langauge of my program without changing the pdf language.
In other words: How can I have the user chose between English, Spanish and German for the program and independently for the pdf preview?
One language works just fine with wxTranslationHelper which uses wxLocale, but two at the same time?
thank you.

Can't you just create another instance of wxTranslations that you manage yourself?

Thanx, might there be a problem with:

Only one wxTranslations instance is active at a time

??

I've never tried it, but i think you can still have another instance that you don't mark as active with Set(). You'll just have to call wxTranslations::GetTranslatedString() manually for each string you want to translate.

I have a follow up question:
After I changed the language setting, is there a way to "refresh" i.e. the label of a button without having to use SetLabel(newLanguageLabel)? I have a lot of controls and am facing a lot of work either recreating the controls or calling SetLabel or similar functions hundreds of times.
I could just restart the programme or the tell the user to do it, but I find it better to change it on the fly.

No. As you said, you either have to iterate over all controls or restart the application.

I personally chose the second option in my programs, because switching the GUI language doesn't happen often and switching it on the fly is just not worth the effort.

That´s what I thought and I also found a post by you that shows how to restart the application, thank you!
