Detailed Description
The QTextDecoder class provides a state-based decoder.
A text decoder converts text from an encoded text format into Unicode using a specific codec.
The decoder converts text in this format into Unicode, remembering any state that is required between calls.
See also QTextCodec::makeDecoder() and QTextEncoder.
Member Function Documentation
QTextDecoder::QTextDecoder(const QTextCodec * codec)
Constructs a text decoder for the given codec.
QTextDecoder::QTextDecoder(const QTextCodec * codec, QTextCodec::ConversionFlags flags)
Constructs a text decoder for the given codec and conversion flags.
This function was introduced in Qt 4.7.
QTextDecoder::~QTextDecoder()
Destroys the decoder.
QString QTextDecoder::toUnicode(const char * chars, int len)
Converts the first len bytes in chars to Unicode, returning the result.
If not all characters are used (e.g. if only part of a multi-byte encoding is at the end of the characters), the decoder remembers enough state to continue with the next call to this function.
void QTextDecoder::toUnicode(QString * target, const char * chars, int len)
This is an overloaded function.
The converted string is returned in target.
QString QTextDecoder::toUnicode(const QByteArray & ba)
This is an overloaded function.
Converts the bytes in the byte array specified by ba to Unicode and returns the result.
