Подробное описаниеThe QTextCodecPlugin class provides an abstract base for custom QTextCodec plugins. The text codec plugin is a simple plugin interface that makes it easy to create custom text codecs that can be loaded dynamically into applications. Writing a text codec plugin is achieved by subclassing this base class, reimplementing the pure virtual functions names(), aliases(), createForName(), mibEnums() and createForMib(), and exporting the class with the Q_EXPORT_PLUGIN2() macro. See How to Create Qt Plugins for details. See the IANA character-sets encoding file for more information on mime names and mib enums. Описание функций-членовQTextCodecPlugin::QTextCodecPlugin ( QObject * parent = 0 )Constructs a text codec plugin with the given parent. This is invoked automatically by the Q_EXPORT_PLUGIN2() macro. QTextCodecPlugin::~QTextCodecPlugin ()Destroys the text codec plugin. You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used. QList<QByteArray> QTextCodecPlugin::aliases () const [pure virtual]Returns the list of aliases supported by this plugin. QTextCodec * QTextCodecPlugin::createForMib ( int mib ) [pure virtual]Creates a QTextCodec object for the mib enum mib. See the IANA character-sets encoding file for more information. See also mibEnums(). QTextCodec * QTextCodecPlugin::createForName ( const QByteArray & name ) [pure virtual]Creates a QTextCodec object for the codec called name. The name must come from the list of encodings returned by names(). Encoding names are case sensitive. Пример: QList<QByteArray> MyCodecPlugin::names() const { return QList<QByteArray> << "IBM01140" << "hp15-tw"; } QTextCodec *MyCodecPlugin::createForName(const QByteArray &name) { if (name == "IBM01140") { return new Ibm01140Codec; } else if (name == "hp15-tw") { return new Hp15TwCodec; } return 0; } See also names(). QList<int> QTextCodecPlugin::mibEnums () const [pure virtual]Returns the list of mib enums supported by this plugin. See also createForMib(). QList<QByteArray> QTextCodecPlugin::names () const [pure virtual]Returns the list of MIME names supported by this plugin. If a codec has several names, the extra names are returned by aliases(). See also createForName() and aliases(). |
