  form1() {
    text("Translator example"_t);
    client_size({500, 300});
    controls().add_range({open_button, close_button, text_label});
    
    open_button.location({10, 10});
    open_button.text("Open"_t);
    
    close_button.location({100, 10});
    close_button.text("Close"_t);
    
    text_label.location({10, 50});
    text_label.auto_size(true);
    text_label.text("The quick brown fox jumps over the lazy dog."_t);
  }
  
private:
  button open_button;
  button close_button;
  label text_label;
};
 
auto main() -> int {
  try {
    //translator::locale("ar_MA");
    //translator::locale("es_ES");
    //translator::locale("fr_FR");
    translator::locale("ru_RU");
  } catch (const std::exception& e) {
    message_box::show(string::format("Make sure specified locale is installed on your system :\n\n{}", e.what()), "Exception");
    return -1;
  }
  application::run(form1 {});

Member Function Documentation

language() [1/2]

static xtd::string xtd::translator::language ( )

static

Gets the current application language.

Returns

The current application language.

Remarks

By default language is initialized with the current system language.

language() [2/2]

static void xtd::translator::language ( const xtd::string & language )

static

Sets the current application language.

Parameters

language

The current application language.

Remarks

Normally you should use the std::locale() method. This function only exists if you have a good reason to bypass std::locale().

Warning

If you set the language with this method, and you use the std::locale method afterwards, translator will use the language initialized with this method and not with std::locale().

locale() [1/3]

static std::locale xtd::translator::locale ( )

static

Gets the global locale.

Returns

The global locale.

Remarks

is same a call std::locale {};

locale() [2/3]

static void xtd::translator::locale ( const xtd::string & value )

static

Sets the global locale.

Parameters

value

The global locale.

Remarks

is same a call std::locale::global(std::locale {value});

locale() [3/3]

static void xtd::translator::locale ( const std::locale & value )

static

Sets the global locale.

Parameters

value

The global locale.

Remarks

is same a call std::locale::global(value);

languages()

static xtd::array< xtd::string > xtd::translator::languages ( )

static

Gets an array of languages supported by the application.

Returns

An array of languages supported by the application.

system_language()

static xtd::string xtd::translator::system_language ( )

static

Gets the current system language.

Returns

The current system language.

add_value()

static void xtd::translator::add_value ( const xtd::string & language, const xtd::string & key, const xtd::string & value )

static

Manually adds a translation for a specified key and language.

Parameters

language	The language of the key to be translated.
key	The key to be translated. @parama value The translation of the key for the specified language.

Warning

This method should not be used. The translation is normally done automatically. This method is present only if you want to make an instant translation on a very small number of keys. It would not be wise to translate an entire application into different languages with this method.

parse_locale()

static void xtd::translator::parse_locale ( const xtd::string & locale_path )

static

Parses a specified path that contains translations.

Parameters

locale_path

Path that contains translations.

parse_file()

static void xtd::translator::parse_file ( const xtd::string & file, const xtd::string & language )

static

Parses a specified file that contains translations for a specified language.

Parameters

file	The file that contains translations.
language	The language of the translation file.

translate() [1/2]

static xtd::string xtd::translator::translate ( const xtd::string & value )

staticnoexcept

Translates a string into the lganguage specified by the xtd::translate::language property.

Returns

The translated string.

Remarks

If no translation is found, the result is the same as the value.

translate() [2/2]

static xtd::string xtd::translator::translate ( const xtd::string & language, const xtd::string & value )

staticnoexcept

Translates a string into the specified lganguage.

Returns

The translated string.

Parameters

language

The language used to translate the value

Remarks

If no translation is found, the result is the same as the value.
