/**
* This class is tdehtml's main class. It features an almost complete
* web browser, and html renderer.
*
* The easiest way to use this class (if you just want to display an HTML
* page at some URL) is the following:
*
* \code
* KURL url = "http://www.kde.org";
* TDEHTMLPart *w = new TDEHTMLPart();
* w->openURL(url);
* w->view()->resize(500, 400);
* w->show();
* \endcode
*
* Java and JavaScript are enabled by default depending on the user's
* settings. If you do not need them, and especially if you display
* unfiltered data from untrusted sources, it is strongly recommended to
* turn them off. In that case, you should also turn off the automatic
* redirect and plugins:
*
* \code
* w->setJScriptEnabled(false);
* w->setJavaEnabled(false);
* w->setMetaRefreshEnabled(false);
* w->setPluginsEnabled(false);
* \endcode
*
* You may also wish to disable external references. This will prevent TDEHTML
* from loading images, frames, etc, or redirecting to external sites.
*
* \code
* w->setOnlyLocalReferences(true);
* \endcode
*
* Some apps want to write their HTML code directly into the widget instead of
* opening an url. You can do this in the following way:
*
* \code
* TQString myHTMLCode = ...;
* TDEHTMLPart *w = new TDEHTMLPart();
* w->begin();
* w->write(myHTMLCode);
* ...
* w->end();
* \endcode
*
* You can do as many calls to write() as you wish. There are two
* write() methods, one accepting a TQString and one accepting a
* @p char @p * argument. You should use one or the other
* (but not both) since the method using
* the @p char @p * argument does an additional decoding step to convert the
* written data to Unicode.
*
* It is also possible to write content to the HTML part using the
* standard streaming API from KParts::ReadOnlyPart. The usage of
* the API is similar to that of the begin(), write(), end() process
* described above as the following example shows:
*
* \code
* TDEHTMLPart *doc = new TDEHTMLPart();
* doc->openStream( "text/html", KURL() );
* doc->writeStream( TQCString( "<html><body><p>TDEHTML Rocks!</p></body></html>" ) );
* doc->closeStream();
* \endcode
*
* @short HTML Browser Widget
