Member Typedef Documentation

◆ StringMap

typedef QMap<QString, QString> QtlIsoLanguages::StringMap

private

Mapping a string to another string.

Constructor & Destructor Documentation

◆ QtlIsoLanguages()

QtlIsoLanguages::QtlIsoLanguages ( )

private

Private constructor.

Member Function Documentation

◆ instance()

const QtlIsoLanguages * QtlIsoLanguages::instance ( )

static

Get the single instance of QtlIsoLanguages.

Returns: The single instance of QtlIsoLanguages.

◆ languageName()

QString QtlIsoLanguages::languageName	(	const QString &	code,
		const QString &	defaultValue = `QString()`
	)		const

Get a localized language name from a language code.

Parameters

code	The language code as a string, either an ISO 639-1 2-letter code or an ISO 638-2 3-letter code.
defaultValue	The string value to return is code is not found. By default, return the code string if not found. If defaultValue is an explicit empty string (""), then the empty string will be returned if code is not found.

Returns: The corresponding language code or a default value if not found.

◆ countryName()

QString QtlIsoLanguages::countryName	(	const QString &	code,
		const QString &	defaultValue = `QString()`
	)		const

Get a localized country name from a country code.

Parameters

code	The ISO 6166-1 country code as a string, either a 2-letter, 3-letter or 3-digit code.
defaultValue	The string value to return is code is not found. By default, return the code string if not found. If defaultValue is an explicit empty string (""), then the empty string will be returned if code is not found.

Returns: The corresponding country code or a default value if not found.

◆ language2LetterCodes()

Returns: The sorted list of all ISO 639-1 2-letter codes for language names.

◆ language3LetterCodes()

QStringList QtlIsoLanguages::language3LetterCodes ( ) const

inline

Get the sorted list of all ISO 639-2 3-letter codes for language names.

Returns: The sorted list of all ISO 639-2 3-letter codes for language names.

◆ country2LetterCodes()

QStringList QtlIsoLanguages::country2LetterCodes ( ) const

inline

Get the sorted list of all ISO 3166 2-letter codes for country names.

Returns: The sorted list of all ISO 3166 2-letter codes for country names.

◆ country3LetterCodes()

QStringList QtlIsoLanguages::country3LetterCodes ( ) const

◆ country3DigitCodes()

QStringList QtlIsoLanguages::country3DigitCodes ( ) const

inline

Get the sorted list of all ISO 3166 3-digit codes for country names.

Returns: The sorted list of all ISO 3166 3-digit codes for country names.

◆ codeList()

QStringList QtlIsoLanguages::codeList ( const StringMap & map ) const

private

Get the sorted list of all codes for a given map.

Returns: The sorted list of all codes for a given map.

◆ addLanguage()

void QtlIsoLanguages::addLanguage	(	const QString &	code3,
		const QString &	code3alt,
		const QString &	code2,
		const QString &	name
	)
