Detailed Description

This class is khtml's main class.HTML Browser Widget.

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:

 KURL url = "http://www.kde.org";
 KHTMLPart *w = new KHTMLPart();
 w->openURL(url);
 w->view()->resize(500, 400);
 w->show();

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:

 w->setJScriptEnabled(false);
 w->setJavaEnabled(false);
 w->setMetaRefreshEnabled(false);
 w->setPluginsEnabled(false);

You may also wish to disable external references. This will prevent KHTML from loading images, frames, etc, or redirecting to external sites.

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:

 QString myHTMLCode = ...;
 KHTMLPart *w = new KHTMLPart();
 w->begin();
 w->write(myHTMLCode);
 ...
 w->end();

You can do as many calls to write() as you wish. There are two write() methods, one accepting a QString and one accepting a char * argument. You should use one or the other (but not both) since the method using the char * 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:

 KHTMLPart *doc = new KHTMLPart();
 doc->openStream( "text/html", KURL() );
 doc->writeStream( QCString( "<html><body><p>KHTML Rocks!</p></body></html>" ) );
 doc->closeStream();

Constructor & Destructor Documentation

KHTMLPart::KHTMLPart QWidget parentWidget = 0,
const char *  widgetname = 0,
QObject parent = 0,
const char *  name = 0,
GUIProfile  prof = DefaultGUI
 

Constructs a new KHTMLPart.

KHTML basically consists of two objects: The KHTMLPart itself, holding the document data (DOM document), and the KHTMLView, derived from QScrollView, in which the document content is rendered in. You can specify two different parent objects for a KHTMLPart, one parent for the KHTMLPart document and on parent for the KHTMLView. If the second parent argument is 0L, then parentWidget is used as parent for both objects, the part and the view.

Definition at line 206 of file khtml_part.cpp.

KHTMLPart::~KHTMLPart  )  [virtual]
 

Destructor.

Definition at line 468 of file khtml_part.cpp.


Member Function Documentation

DOM::Node KHTMLPart::activeNode  )  const
 

Returns the node that has the keyboard focus.

Definition at line 6926 of file khtml_part.cpp.

bool KHTMLPart::autoloadImages  )  const
 

Returns whether images contained in the document are loaded automatically or not.

Note:
that the returned information is unrelieable as long as no begin() was called.

KURL KHTMLPart::backgroundURL  )  const
 

Returns the URL for the background Image (used by save background).

Definition at line 4096 of file khtml_part.cpp.

void KHTMLPart::begin const KURL url = KURL(),
int  xOffset = 0,
int  yOffset = 0
[virtual]
 

Clears the widget and prepares it for new content.

If you want url() to return for example "file:/tmp/test.html", you can use the following code:

 view->begin( KURL("file:/tmp/test.html" ) );

Parameters:
url is the url of the document to be displayed. Even if you are generating the HTML on the fly, it may be useful to specify a directory so that any pixmaps are found.
xOffset is the initial horizontal scrollbar value. Usually you don't want to use this.
yOffset is the initial vertical scrollbar value. Usually you don't want to use this.
All child frames and the old document are removed if you call this method.

Definition at line 1867 of file khtml_part.cpp.

KParts::BrowserExtension * KHTMLPart::browserExtension  )  const
 

Returns a pointer to the KParts::BrowserExtension.

Definition at line 897 of file khtml_part.cpp.

KHTMLPart::CaretDisplayPolicy KHTMLPart::caretDisplayPolicyNonFocused  )  const
 

Returns the current caret policy when the view is not focused.

Since:
3.2

Definition at line 2684 of file khtml_part.cpp.

void KHTMLPart::caretPositionChanged const DOM::Node node,
long  offset
[signal]
 

This signal is emitted whenever the caret position has been changed.

The signal transmits the position the DOM::Range way, the node and the zero-based offset within this node.

Parameters:
node node which the caret is in. This can be null if the caret has been deactivated.
offset offset within the node. If the node is null, the offset is meaningless.
Since:
3.2

bool KHTMLPart::closeURL  )  [virtual]
 

Stops loading the document and kills all data requests (for images, etc.

)

Reimplemented from KParts::ReadOnlyPart.

QObject parent,
const char *  name,
const QString mimetype,

[protected, virtual]
 

This method is called when a new embedded object (include html frames) is to be created.

Reimplement it if you want to add support for certain embeddable objects without registering them in the KDE wide registry system (KSyCoCa) . Another reason for re-implementing this method could be if you want to derive from KTHMLPart and also want all html frame objects to be a object of your derived type, in which case you should return a new instance for the mimetype 'text/html' .

Definition at line 940 of file khtml_part.cpp.

KJS::Interpreter * KHTMLPart::jScriptInterpreter  ) 
 

Returns the JavaScript interpreter the part is using.

This method is mainly intended for applications which embed and extend the part and provides a mechanism for adding additional native objects to the interpreter (or removing the built-ins).

One thing people using this method to add things to the interpreter must consider, is that when you start writing new content to the part, the interpreter is cleared. This includes both use of the begin( const KURL &, int, int ) method, and the openURL( const KURL & ) method. If you want your objects to have a longer lifespan, then you must retain a KJS::Object yourself to ensure that the reference count of your custom objects never reaches 0. You will also need to re-add your bindings everytime this happens - one way to detect the need for this is to connect to the docCreated() signal, another is to reimplement the begin() method.

void KHTMLPart::write const QString str  )  [virtual]
 

Writes another part of the HTML code to the widget.

Definition at line 1983 of file khtml_part.cpp.

void KHTMLPart::write const char *  str,
int  len = -1
[virtual]
 

Writes another part of the HTML code to the widget.

You may call this function many times in sequence. But remember: The fewer calls you make, the faster the widget will be.

The HTML code is send through a decoder which decodes the stream to Unicode.

The len parameter is needed for streams encoded in utf-16, since these can have \0 chars in them. In case the encoding you're using isn't utf-16, you can safely leave out the length parameter.

Attention: Don't mix calls to write( const char *) with calls to write( const QString & ).

The result might not be what you want.

int KHTMLPart::zoomFactor  )  const
 

Returns the current zoom factor.
