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 + * @author Lars Knoll (knoll@kde.org) + * + */ +class TDEHTML_EXPORT TDEHTMLPart : public KParts::ReadOnlyPart +{ + Q_OBJECT + friend class TDEHTMLView; + friend class DOM::HTMLTitleElementImpl; + friend class DOM::HTMLFrameElementImpl; + friend class DOM::HTMLIFrameElementImpl; + friend class DOM::HTMLObjectElementImpl; + friend class DOM::HTMLAnchorElementImpl; + friend class DOM::HTMLMetaElementImpl; + friend class DOM::NodeImpl; + friend class TDEHTMLRun; + friend class DOM::HTMLFormElementImpl; + friend class tdehtml::RenderPartObject; + friend class KJS::Window; + friend class KJS::ScheduledAction; + friend class KJS::JSNodeFilter; + friend class KJS::WindowFunc; + friend class KJS::ExternalFunc; + friend class KJS::JSEventListener; + friend class KJS::JSLazyEventListener; + friend class KJS::DOMDocument; + friend class KJS::SourceFile; + friend class KJSProxy; + friend class TDEHTMLPartBrowserExtension; + friend class DOM::DocumentImpl; + friend class DOM::HTMLDocumentImpl; + friend class TDEHTMLPartBrowserHostExtension; + friend class tdehtml::HTMLTokenizer; + friend class tdehtml::XMLTokenizer; + friend class tdehtml::RenderWidget; + friend class tdehtml::CSSStyleSelector; + friend class TDEHTMLPartIface; + friend class TDEHTMLPartFunction; + friend class TDEHTMLPopupGUIClient; + + TQ_PROPERTY( bool javaScriptEnabled READ jScriptEnabled WRITE setJScriptEnabled ) + TQ_PROPERTY( bool javaEnabled READ javaEnabled WRITE setJavaEnabled ) + TQ_PROPERTY( bool autoloadImages READ autoloadImages WRITE setAutoloadImages ) + TQ_PROPERTY( bool dndEnabled READ dndEnabled WRITE setDNDEnabled ) + TQ_PROPERTY( bool pluginsEnabled READ pluginsEnabled WRITE setPluginsEnabled ) + + /* + * + * Don't add setOnlyLocalReferences here.
