# Translation (/examples/others/translation)



Register multi-language string tables and switch locales at runtime.

Static and dynamic translation packs [#static-and-dynamic-translation-packs]

<LvglExampleBrief>
  Register two translation sources and print labels via 

  `lv_tr`

  .
</LvglExampleBrief>

A static pack provides the tags `tiger`, `lion`, `rabbit`, and `elephant` in
English, German, and Spanish through `lv_translation_add_static`. A dynamic
pack built with `lv_translation_add_dynamic` adds the tags `table` and
`chair` for English and German using `lv_translation_add_tag` and
`lv_translation_set_tag_translation`. `lv_translation_set_language("de")`
selects German and two labels render the `tiger` and `chair` translations
through `lv_tr`.

Live language switching from a dropdown [#live-language-switching-from-a-dropdown]

<LvglExampleBrief>
  Refresh translated labels on 

  `LV_EVENT_TRANSLATION_LANGUAGE_CHANGED`

  .
</LvglExampleBrief>

A dropdown lists the entries in the `languages` array (English, Deutsch, Español). Its
`LV_EVENT_VALUE_CHANGED` callback reads the selected string and calls
`lv_translation_set_language`. One label is created per tag in the `tags`
array and subscribes to `LV_EVENT_TRANSLATION_LANGUAGE_CHANGED`; the handler
rewrites its text with `lv_tr(tag)`. The screen uses a centered column flex
layout and starts in English.
