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"; + * KHTMLPart *w = new KHTMLPart(); + * 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 KHTML + * 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 = ...; + * KHTMLPart *w = new KHTMLPart(); + * 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 + * KHTMLPart *doc = new KHTMLPart(); + * doc->openStream( "text/html", KURL() ); + * doc->writeStream( TQCString( "

KHTML Rocks!
