# KHTMLPart Class Reference

`from PyKDE4.khtml import *`

Inherits: KParts.ReadOnlyPart → KParts.Part → QObject

## Detailed Description

This class is khtml'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:

     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.

     w->setOnlyLocalReferences(true);

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();

## Signal Documentation

caretPositionChanged | ( | DOM.Node | node,
|  | long | offset
| ) |  |  |

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.

Signal syntax:
  `QObject.connect(source, SIGNAL("caretPositionChanged(const DOM::Node&, long)"), target_slot)`

configurationChanged | ( |  | ) |

Emitted whenever the configuration has changed

Signal syntax:
  `QObject.connect(source, SIGNAL("configurationChanged()"), target_slot)`

docCreated | ( |  | ) |

Internal:

Signal syntax:
  `QObject.connect(source, SIGNAL("docCreated()"), target_slot)`

formSubmitNotification | ( | QString | action,
|  | QString | url,
|  | QByteArray | formData,
|  | QString | target,
|  | QString | contentType,
|  | QString | boundary
| ) |  |  |

If form notification is on, this will be emitted either for a form submit or before the form submit according to the setting. ### KDE4 remove me

Signal syntax:
  `QObject.connect(source, SIGNAL("formSubmitNotification(const char*, const QString&, const QByteArray&, const QString&, const QString&, const QString&)"), target_slot)`

nodeActivated | ( | DOM.Node | a0
| ) |  |  |

This signal is emitted when an element retrieves the keyboard focus. Note that the signal argument can be a null node if no element is active, meaning a node has explicitly been deactivated without a new one becoming active.

Signal syntax:
  `QObject.connect(source, SIGNAL("nodeActivated(const DOM::Node&)"), target_slot)`

onURL | ( | QString | url
| ) |  |  |

Emitted if the cursor is moved over an URL.

Signal syntax:
  `QObject.connect(source, SIGNAL("onURL(const QString&)"), target_slot)`

popupMenu | ( | QString | url,
|  | QPoint | point
| ) |  |  |

Emitted when the user clicks the right mouse button on the document. See KParts.BrowserExtension for two more popupMenu signals emitted by khtml, with much more information in the signal.

Signal syntax:
  `QObject.connect(source, SIGNAL("popupMenu(const QString&, const QPoint&)"), target_slot)`

selectionChanged | ( |  | ) |

This signal is emitted when the selection changes.

Signal syntax:
  `QObject.connect(source, SIGNAL("selectionChanged()"), target_slot)`

## Method Documentation

__init__ | ( | self, |
|  | QWidget | parentWidget=0,
|  | QObject | parent=0,
|  | KHTMLPart.GUIProfile | prof=KHTMLPart.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 QScrollArea, 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 one 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.

__init__ | ( | self, |
|  | KHTMLView | view,
|  | QObject | parent=0,
|  | KHTMLPart.GUIProfile | prof=KHTMLPart.DefaultGUI
| ) |  |  |

Constructs a new KHTMLPart.

This constructor is useful if you wish to subclass KHTMLView. If the view passed as first argument to the constructor was built with a null KHTMLPart pointer, then the newly created KHTMLPart will be assigned as the view's part.

Therefore, you might either initialize the view as part of the initialization list of your derived KHTMLPart class constructor:

       MyKHTMLPart() : KHTMLPart( new MyKHTMLView( this ), ...

Or separately build the KHTMLView beforehand:

       KHTMLView * v = KHTMLView( 0L, parentWidget());
       KHTMLPart * p = KHTMLPart( v ); // p will be assigned to v, so that v->part() == p

DOM.Node activeNode | ( |  | self ) |

Returns the node that has the keyboard focus.

bool autoloadImages | ( |  | self ) |

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 backgroundURL | ( |  | self ) |

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

KUrl baseURL | ( |  | self ) |

begin | ( | self, |
|  | KUrl | url=KUrl(),
|  | int | xOffset=0,
|  | int | yOffset=0
| ) |  |  |

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.

KParts.BrowserExtension browserExtension | ( |  | self ) |

Returns a pointer to the KParts.BrowserExtension.

KParts.BrowserHostExtension browserHostExtension | ( |  | self ) |

|  | QWidget | parentWidget,
|  | QObject | parent,
|  | QString | mimetype,
|  | QString | serviceName,
|  | QStringList | serviceTypes,
|  | QStringList | params
| ) |  |  |

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' .

KParts.ReadOnlyPart currentFrame | ( |  | self ) |

Return the current frame (the one that has focus) Not necessarily a direct child of ours, framesets can be nested. Returns "this" if this part isn't a frameset.

|  | bool | extendSelection=0
| ) |  |  |

Sets the caret to the given position.

If the given location is invalid, it will snap to the nearest valid location. Immediately afterwards a caretPositionChanged signal containing the effective position is emitted

Parameters:

  | node | node to set to
  | offset | zero-based offset within the node
  | extendSelection | If true, a selection will be spanned from the last caret position to the given one. Otherwise, any existing selection will be deselected.

setCaretVisible | ( | self, |
|  | bool | show
| ) |  |  |

Sets the visibility of the caret.

This methods displays or hides the caret regardless of the current caret display policy (see setCaretDisplayNonFocused), and regardless of focus.

The caret will be shown/hidden only under at least one of the following conditions:

- the document is editable
- the document is in caret mode
- the document's currently focused element is editable

Parameters:

  | show | true to make visible, false to hide.

setDNSPrefetch | ( | self, |
|  | KHTMLPart.DNSPrefetch | pmode
| ) |  |  |

Sets whether DNS Names found in loaded documents'anchors should be pre-fetched (pre-resolved). Note that calling this function will permanently override the User settings about DNS prefetch support. Not calling this function is the only way to let the default settings apply.

Note:
  This setting has no effect if setOnlyLocalReferences() mode is enabled.

Parameters:

  | pmode | the mode to set. See DNSPrefetch enum for explanation of values.

Since:
  4.2

setEditable | ( | self, |
|  | bool | enable
| ) |  |  |

Makes the document editable.

Setting this property to true makes the document, and its subdocuments (such as frames, iframes, objects) editable as a whole. FIXME: insert more information about navigation, features etc. as seen fit

Parameters:

  | enable | true to set document editable, false to set it read-only.

bool setEncoding | ( | self, |
|  | QString | name,
|  | bool | override=0

|  | QString | name
| ) |  |  |

Sets the fixed font style.

Parameters:

  | name | The font name to use for fixed text, e.g. the <tt>&lt;pre&gt;</tt> tag.

setFontScaleFactor | ( | self, |
|  | int | percent
| ) |  |  |

Sets the scale factor to be applied to fonts. The value is given in percent, larger values mean generally larger fonts.

The given value should be in the range of 20..300, values outside that range are not guaranteed to work. A value of 100 will disable all scaling of font sizes and show the page with the sizes determined via the given lengths in the stylesheets.

setForcePermitLocalImages | ( | self, |
|  | bool | enable
| ) |  |  |

Security option. If this is set to true, content loaded from external URLs will be permitted to access images on disk regardless of of the Kiosk policy. You should be careful in enabling this, as it may make it easier to fake any HTML-based chrome or to perform other such user-confusion attack. false by default.

Since:
  4.6

setFormNotification | ( | self, |
|  | KHTMLPart.FormNotification | fn
| ) |  |  |

Determine if signal should be emitted before, instead or never when a submitForm() happens. ### KDE5 remove me

setJavaEnabled | ( | self, |
|  | bool | enable
| ) |  |  |

Enables/disables Java applet support. Note that calling this function will permanently override the User settings about Java applet support. Not calling this function is the only way to let the default settings apply.

|  | bool | enable
| ) |  |  |

Enable/disable automatic forwarding by &lt;meta http-equiv="refresh" ....&gt;

setOnlyLocalReferences | ( | self, |
|  | bool | enable
| ) |  |  |

Security option.

Specify whether only file:/ or data:/ urls are allowed to be loaded without user confirmation by KHTML. ( for example referenced by stylesheets, images, scripts, subdocuments, embedded elements ).

This option is mainly intended for enabling the "mail reader mode", where you load untrusted content with a file:/ url.

Please note that enabling this option currently automatically disables Javascript, Java and Plugins support. This might change in the future if the security model is becoming more sophisticated, so don't rely on this behaviour.

( default false - everything is loaded unless forbidden by KApplication.authorizeURLAction).

setPluginPageQuestionAsked | ( | self, |
