[虚拟] QTextToSpeechEngine *QTextToSpeechPlugin:: createTextToSpeechEngine (const QVariantMap & 参数 , QObject * parent , QString * errorString ) const

Factory method that is triggered by a call to QTextToSpeech::QTextToSpeech () when a provider name is given in the constructor and a text-to-speech plug-in matching the provider name was successfully loaded.

Value of 参数 is currently always empty.

If an error occurs, the method should return 0 and (optionally) give a description of the error in errorString . In this case, QTextToSpeech::state () 会返回 QTextToSpeech::BackendError .

parent is 0, the caller takes the ownership of the returned engine instance.
