CLASS {Localize_str|ing_constants}
,
UNTESTED, BYTES,
ABSTRACT :



 To localize string constants in a class, it is necessary:
 1. for each string constant (or string constant concatenation expression)
    apply a "function" _name, where name is a localization identifier for the
    string. E.g. _L1("This string is localizable") or "Localizable"._L1
    (all these names must be unique in a class).
 2. call in the application (in a function called on its initialization, e.g.
    in the main form CONSTRUCT) the method Localize.
 3. A text file containing base (not translated) text is created either
    automatically in a default location, or by a call the method
    Save_untranslated (it is recommended to call it directly).
    Such file is named Default_.lng. Just copy it and rename copied file to
    Long_name_sn.lng (where Long_name - is a long name of your language and
    sn - is its short name). And replace desired original strings to
    translated.
 4. To allow for a user to select a language for translating to it, get a list
    of available languages using the function Available_languages (returning
    the list as ';'-separated string), then use the string returned e.g. in a
    combo-box, then set new default current language calling the Set_language
    method.
 All translations are stored in text files looking like ini-files.
 Sections are rely to classes and are named in figure brackets.
 Each translation has a form name=value.
