Property Details

The “auto-load-images” property

  “auto-load-images”         gboolean

Load images automatically.

Flags: Read / Write / Construct

Default value: TRUE


The “auto-resize-window” property

  “auto-resize-window”       gboolean

Web pages can request to modify the size and position of the window containing the WebKitWebView through various DOM methods (resizeTo, moveTo, resizeBy, moveBy). By default WebKit will not honor this requests, but you can set this property to TRUE if you'd like it to do so. If you wish to handle this manually, you can connect to the notify signal for the WebKitWebWindowFeatures of your WebKitWebView.

Flags: Read / Write / Construct

Default value: FALSE

Since 1.1.22


The “auto-shrink-images” property

  “auto-shrink-images”       gboolean

Automatically shrink standalone images to fit.

Flags: Read / Write / Construct

Default value: TRUE

  “cursive-font-family”      gchar *

The default Cursive font family used to display text.

Flags: Read / Write / Construct

Default value: "serif"


The “default-encoding” property

  “default-encoding”         gchar *

The default encoding used to display text.

Flags: Read / Write / Construct

Default value: "iso-8859-1"


The “default-font-family” property

The default font size used to display monospace text.

Flags: Read / Write / Construct

Allowed values: >= 5

Default value: 10


The “editing-behavior” property

  “editing-behavior”         WebKitEditingBehavior

This setting controls various editing behaviors that differ between platforms and that have been combined in two groups, 'Mac' and 'Windows'. Some examples:

1) Clicking below the last line of an editable area puts the caret at the end of the last line on Mac, but in the middle of the last line on Windows.

2) Pushing down the arrow key on the last line puts the caret at the end of the last line on Mac, but does nothing on Windows. A similar case exists on the top line.

Flags: Read / Write / Construct

Default value: WEBKIT_EDITING_BEHAVIOR_UNIX

Since 1.1.13


The “enable-accelerated-compositing” property

  “enable-accelerated-compositing” gboolean

Enable or disable support for accelerated compositing on pages. Accelerated compositing uses the GPU to render animations on pages smoothly and also allows proper rendering of 3D CSS transforms.

Flags: Read / Write / Construct

Default value: FALSE

Since 1.7.5


The “enable-caret-browsing” property

  “enable-caret-browsing”    gboolean

Whether to enable caret browsing mode.

Default value: FALSE

Since 1.1.6


The “enable-default-context-menu” property

  “enable-default-context-menu” gboolean

Whether right-clicks should be handled automatically to create, and display the context menu. Turning this off will make WebKitGTK+ not emit the populate-popup signal. Notice that the default button press event handler may still handle right clicks for other reasons, such as in-page context menus, or right-clicks that are handled by the page itself.

WebKitWebSettings:enable-default-context-menu has been deprecated since version 1.10 and should not be used in newly-written code.

Use “context-menu” signal instead.

Flags: Read / Write / Construct

Default value: TRUE

Since 1.1.18


The “enable-developer-extras” property

  “enable-developer-extras”  gboolean

Whether developer extensions should be enabled. This enables, for now, the Web Inspector, which can be controlled using the WebKitWebInspector instance held by the WebKitWebView this setting is enabled for.

Flags: Read / Write / Construct

Default value: FALSE

Since 1.0.3


The “enable-display-of-insecure-content” property

  “enable-display-of-insecure-content” gboolean

Whether pages loaded via HTTPS should load subresources such as images and frames from non-HTTPS URLs.

Flags: Read / Write / Construct

Default value: TRUE

Since 2.0


The “enable-dns-prefetching” property

  “enable-dns-prefetching”   gboolean

Whether webkit prefetches domain names. This is a separate knob from private browsing. Whether private browsing should set this or not is up for debate, for now it doesn't.

Flags: Read / Write / Construct

Default value: TRUE

Since 1.3.13.


The “enable-dom-paste” property

  “enable-dom-paste”         gboolean

Whether to enable DOM paste. If set to TRUE, document.execCommand("Paste") will correctly execute and paste content of the clipboard.

  “enable-file-access-from-file-uris” gboolean

Boolean property to control file access for file:// URIs. If this option is enabled every file:// will have its own security unique domain.

Flags: Read / Write / Construct

Default value: FALSE

Since 1.1.22


The “enable-frame-flattening” property

  “enable-frame-flattening”  gboolean

Whether to enable the Frame Flattening. With this setting each subframe is expanded to its contents, which will flatten all the frames to become one scrollable page. On touch devices, it is desired to not have any scrollable sub parts of the page as it results in a confusing user experience, with scrolling sometimes scrolling sub parts and at other times scrolling the page itself. For this reason iframes and framesets are barely usable on touch devices.

Flags: Read / Write / Construct

Default value: FALSE

Since 1.3.5


The “enable-fullscreen” property

  “enable-fullscreen”        gboolean

Whether to enable the Javascript Fullscreen API. The API allows any HTML element to request fullscreen display. See also the current draft of the spec: http://www.w3.org/TR/fullscreen/

Flags: Read / Write / Construct

Default value: TRUE

Since 1.1.8


The “enable-html5-local-storage” property

  “enable-html5-local-storage” gboolean

Whether to enable HTML5 localStorage support. localStorage provides simple synchronous storage access.

Flags: Read / Write / Construct

Default value: TRUE

Since 1.1.8


The “enable-hyperlink-auditing” property

  “enable-hyperlink-auditing” gboolean

Enable or disable support for <a ping>.

Flags: Read / Write / Construct

Default value: FALSE

Since 1.2.5


The “enable-java-applet” property

  “enable-java-applet”       gboolean

Flags: Read / Write / Construct

Default value: TRUE

Since 1.1.22


The “enable-media-stream” property

  “enable-media-stream”      gboolean

Enable or disable support for Media Stream on pages. Media Stream is an experimental proposal for allowing web pages to access local video and audio input devices. The standard is currently a work-in-progress as part of the Web Applications 1.0 specification from WHATWG.

See also http://www.w3.org/TR/mediacapture-streams/

Flags: Read / Write / Construct

Default value: FALSE

Since 1.10.0


The “enable-mediasource” property

Flags: Read / Write / Construct

Default value: FALSE

Since 2.4


The “enable-offline-web-application-cache” property

Flags: Read / Write / Construct

Default value: TRUE

Since 1.1.13


The “enable-page-cache” property

  “enable-page-cache”        gboolean

Enable or disable the page cache. Disabling the page cache is generally only useful for special circumstances like low-memory scenarios or special purpose applications like static HTML viewers. This setting only controls the Page Cache, this cache is different than the disk-based or memory-based traditional resource caches, its point is to make going back and forth between pages much faster. For details about the different types of caches and their purposes see: http://webkit.org/blog/427/webkit-page-cache-i-the-basics/

Flags: Read / Write / Construct

Default value: FALSE

Flags: Read / Write / Construct

Default value: FALSE

Since 1.9.0


The “enable-spatial-navigation” property

  “enable-spatial-navigation” gboolean

Whether to enable the Spatial Navigation. This feature consists in the ability to navigate between focusable elements in a Web page, such as hyperlinks and form controls, by using Left, Right, Up and Down arrow keys.
