Detailed Description
The 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(), createForName(), mibEnums() and createForMib(), and exporting the class with the Q_EXPORT_PLUGIN macro. See the Qt Plugins documentation for details.
See the IANA character-sets encoding file for more information on mime names and mib enums.
See also Plugins.
Member Function Documentation
QTextCodecPlugin::QTextCodecPlugin ()
Constructs a text codec plugin. This is invoked automatically by the Q_EXPORT_PLUGIN 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.
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 QString & name ) [pure virtual]
Creates a QTextCodec object for the codec called name.
See also names().
QValueList<int> QTextCodecPlugin::mibEnums () const [pure virtual]
Returns the list of mib enums this plugin supports.
See also createForMib().
QStringList QTextCodecPlugin::names () const [pure virtual]
Returns the list of mime names this plugin supports.
See also createForName().
