◆ aliases()

QList<QByteArray> QFontGbkCodec::aliases ( ) const
inlinevirtual

Subclasses can return a number of aliases for the codec in question.

Standard aliases for codecs can be found in the IANA character-sets encoding file.

Reimplemented from QTextCodec.

◆ convertFromUnicode()

QByteArray QFontGbkCodec::convertFromUnicode ( const QChar input,
int  number,
ConverterState state 
) const
virtual

QTextCodec subclasses must reimplement this function.

Converts the first number of characters from the input array from Unicode to the encoding of the subclass, and returns the result in a QByteArray.

state can be 0 in which case the conversion is stateless and default conversion rules should be used. If state is not 0, the codec should save the state after the conversion in state, and adjust the remainingChars and invalidChars members of the struct.

Implements QTextCodec.

char * data()
Returns a pointer to the data stored in the byte array.
Definition: qbytearray.h:429
The QByteArray class provides an array of bytes.
Definition: qbytearray.h:135
The QChar class provides a 16-bit Unicode character.
Definition: qchar.h:72
unsigned char uchar
Definition: qglobal.h:994
void resize(int size)
Sets the size of the byte array to size bytes.
int qt_UnicodeToGbk(uint unicode, uchar *gbchar)

◆ convertToUnicode()

QString QFontGbkCodec::convertToUnicode ( const char *  chars,
int  len,
ConverterState state 
) const
virtual

QTextCodec subclasses must reimplement this function.

Converts the first len characters of chars from the encoding of the subclass to Unicode, and returns the result in a QString.

state can be 0, in which case the conversion is stateless and default conversion rules should be used. If state is not 0, the codec should save the state after the conversion in state, and adjust the remainingChars and invalidChars members of the struct.

Implements QTextCodec.

657 {
658  return QString();
659 }
The QString class provides a Unicode character string.
Definition: qstring.h:83

◆ mibEnum()

int QFontGbkCodec::mibEnum ( ) const
inlinevirtual

Subclasses of QTextCodec must reimplement this function.

It returns the MIBenum (see IANA character-sets encoding file for more information). It is important that each QTextCodec subclass returns the correct unique value for this function.

Implements QTextCodec.

Definition at line 131 of file qgb18030codec.h.

131 { return _mibEnum(); }
static int _mibEnum()

◆ name()

QByteArray QFontGbkCodec::name ( ) const
inlinevirtual

QTextCodec subclasses must reimplement this function.

It returns the name of the encoding supported by the subclass.

If the codec is registered as a character set in the IANA character-sets encoding file this method should return the preferred mime name for the codec if defined, otherwise its name.

Implements QTextCodec.

Definition at line 129 of file qgb18030codec.h.
