<h2>Detailed Description</h2>
|
|
<p>The QTextCodecPlugin class provides an abstract base for custom <a href="qtextcodec.html">QTextCodec</a> plugins.</p>
|
|
<p>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.</p>
|
|
<p>Writing a text codec plugin is achieved by subclassing this base class, reimplementing the pure virtual functions <a href="qtextcodecplugin.html#names">names</a>(), <a href="qtextcodecplugin.html#aliases">aliases</a>(), <a href="qtextcodecplugin.html#createForName">createForName</a>(), <a href="qtextcodecplugin.html#mibEnums">mibEnums</a>() and <a href="qtextcodecplugin.html#createForMib">createForMib</a>(), and exporting the class with the <a href="qtplugin.html#Q_EXPORT_PLUGIN2">Q_EXPORT_PLUGIN2</a>() macro. See <a href="plugins-howto.html">How to Create Qt Plugins</a> for details.</p>
|
|
<p>See the <a href="http://www.iana.org/assignments/character-sets">IANA character-sets encoding file</a> for more information on mime names and mib enums.</p>
