TranslationModules - Let CEGUI translate your strings

Postby Hanmac » Wed Aug 31, 2011 10:39

hay i had the idea to add translation modules into cegui for translating the strings in the Windows and Widgets

Example usage without TranslationModule:
if you want to make your menu multi language, you must change the setted text every time you change the language
this could be very annoying

Example usage with TranslationModule:
you change the language and the Windows look after translations for the new language in the TranslationModule which is setted to the system,
so you must not change the Text values of the windows.

Code examples:
  • gettext - which reads the po files, for setting the language, uselocale is used for tread-safe

    Code: Select all

    TranslationSystem* trans = new GettextTranslationSystem;
    trans->setProperty("Domain","cegui");
    trans->setProperty("DomainDirectory",".");
    std::cout << trans->translate("hello how are you?","de"); //"Wie geht es dir?"

  • TMX xml-files - an file that holds multible translations you can see the spec there

    Code: Select all

    TranslationSystem* trans = new TmxTranslationSystem;
    static_cast<TmxTranslationSystem*>(trans)->handleFile("translations.tmx");
    std::cout << trans->translate("hello how are you?","de"); //"Wie geht es dir?"
  • when using with system you could do that (after you use setTranslationSystem)

    Code: Select all

    std::cout << System::getSingleton().getTranslationSystem().translate("hello how are you?","de"); //"Wie geht es dir?"

latest branch on bitbucket

Code: Select all

Could you please add how this is to be used with layouts and properties? How will the syntax look like in .layout files and .looknfeel files, possibly others (this might also apply to .animation files and maybe others as well).

i planed that you does noz need to change it in the layout files because it use the string, and try to translate them

or add it to layout-Property like:

Code: Select all

<Property name="Text" value="English Text" xml:lang="en"/>
<Property name="Text" value="German Text" xml:lang="de"/>


but this function is not implmented
