Can't change the language inside Mixxx

[Albert Santoni]

It's not uncommon for users to run an operating system with a different locale than what they'd actually prefer Mixxx to be in. In other words, you may not want Mixxx to be in the same language as the rest of your OS.

For these users, we should offer an option to change the language in the preferences. (It's OK if we have to ask the user to restart the program.)

For bonus points, you could implement dynamically changing the language:

FYI for anyone that might see this, there is currently a command-line option (in 1.10.0 and above) that lets you do this.
--locale de for example

I've come up with a quick solution in this patch. It adds a combo box to the Interface preferences menu with all the available locales, and stores the selection in [Config] Locale.
Curiously, on my machine, the QLocale(QString name) constructor fails to resolve to a proper locale for 3 of the locales, so 'C' is returned instead. Namely 'eo', 'ia', and 'lb'. Does this happen for anyone else?

Thanks for the patch. I tried on MacOS and 'C' is returned instead for 'eo', 'ia', and 'lb' . Other than that it works fine. Might be a QT issue, cause another qt app (Clementine player) display the same faulty locale strings.

Maybe we could add a 'system default' to the drop down menue that is selected by default. By now i had the first entry 'Arabic' selected per default while my system is 'en'. The interface was 'en' though.

Thanks for the feedback. Is it best we hide the locales that don't resolve properly from the list completely, or leave those in?

Hey Tom,
Your patch doesn't work with latest trunk, could you please update it?

[Tom Gascoigne (tgascoigne)]

Hi mutil,

Certainly, here is an up to date patch with a 'System' option added as suggested above. I've also made it so that locales that fail to resolve correctly (display as 'C' in the drop-down) are not shown.

Regards,
Tom Gascoigne

Thanks a lot Tom! I've committed your patch to trunk and it will be released in 1.11.0. Is it ok to credit you as "Tom Gascoigne"?

Brilliant :) Yes, Tom Gascoigne is fine, and I've signed the developer agreement.
