Change UI Language of Qt Tools

How can I change the UI language of the various Qt tools (creator, designer, linguist) without changing the regional settings of Windows?

You can try exporting the LC_ALL variable with a proper language id but I don't know if Windows respects it. It will definitely work on unices.

Thanks, but that doesn't seem to work on Windows. Here it's probably some weird API call.

Meanwhile I renamed the .qm files as a workaround, but I wonder if there isn't a better solution.

Is it possible to change language of qt designer? I am using designer independetly. In the preferences/options, i can't find such an option. I don't have sudo or root permissions. Kindly let me know. Thank you very much.

On Unix/Linux this is easy

LANG=<language-code> designer

e.g.

LANG=en designer
launching in English

LANG=de designer
launching in Geman

LANG=fr designer
launching in French

Cheers,
