详细描述
The QTextEncoder class provides a state-based encoder.
A text encoder converts text from Unicode into an encoded text format using a specific codec.
The encoder converts Unicode into another format, remembering any state that is required between calls.
参见 QTextCodec::makeEncoder() and QTextDecoder.
成员函数
QTextEncoder::QTextEncoder(const QTextCodec *codec)
Constructs a text encoder for the given codec.
QTextEncoder::QTextEncoder(const QTextCodec *codec, QTextCodec::ConversionFlags flags)
Constructs a text encoder for the given codec and conversion flags.
This function was introduced in Qt 4.7.
QTextEncoder::~QTextEncoder()
Destroys the encoder.
QByteArray QTextEncoder::fromUnicode(const QString &str)
Converts the Unicode string str into an encoded QByteArray.
QByteArray QTextEncoder::fromUnicode(const QChar *uc, int len)
This is an overloaded function.
Converts len characters (not bytes) from uc, and returns the result in a QByteArray.
