详细描述

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.

方法文档编制

QTextDecoder.init ( self , QTextCodec codec )

Constructs a text decoder for the given codec .

QTextDecoder.init ( self , QTextCodec codec , QTextCodec.ConversionFlags flags )

Constructs a text decoder for the given codec and conversion flags .

该函数在 Qt 4.7 引入。

QString QTextDecoder.toUnicode ( self , str chars )

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 函数。

QTextDecoder.toUnicode ( self , QString target , str chars )

这是重载函数。

The converted string is returned in target .

QString QTextDecoder.toUnicode ( self , QByteArray ba )

这是重载函数。

Converts the bytes in the byte array specified by ba to Unicode and returns the result.
