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.

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.

void QTextDecoder::toUnicode(QString *target, const char *chars, int len)

This is an overloaded function.

The converted string is returned in target.
