# qtextcodecplugin(3qt)

Abstract base for custom QTextCodec plugins

## NAME

QTextCodecPlugin - Abstract base for custom QTextCodec plugins

## SYNOPSIS

All the functions in this class are reentrant when Qt is built with thread support.\</p\>

`#include <qtextcodecplugin.h>`

### Public Members

**QTextCodecPlugin ()**\
 **~QTextCodecPlugin ()**\
 **virtual QStringList names () const = 0**\
 **virtual QTextCodec \* createForName ( const QString & name ) = 0**\
 **virtual QValueList\<int\> mibEnums () const = 0**\
 **virtual QTextCodec \* createForMib ( int mib ) = 0**\

## 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 supported by this plugin.

See also createForMib().

## QStringList QTextCodecPlugin::names () const` [pure virtual]`

Returns the list of mime names supported by this plugin.

See also createForName().
