The names have + to be consistent with QInputContext::identifierName(). The names + have to consist of ASCII characters only. See also + QInputContext::identifierName() for further information. + + \sa create(), displayName(), QInputContext::identifierName() +*/ + +/*! + \fn QInputContext* QInputContextPlugin::create( const QString& key ) + + Creates and returns a QInputContext instance for the input context key \a key. + The input context key is usually the class name of the required input method. + + \sa keys() +*/ + +/*! + \fn QStringList languages( const QString &key ) + + Returns what languages are supported by the QInputContext instance + specified by \a key. + + The languages are expressed as language code (e.g. "zh_CN", + "zh_TW", "zh_HK", "ja", "ko", ...).

Another + name is called 'identifier name' to identify and specify input + methods for the input method switching mechanism and so on. + + Although tr( identifierName ) can provide user friendly i18n-ized + name without this function, the message catalog have to be managed + by Qt in the case.
