Settings#

class Settings(**properties: Any)#

Superclasses: Object

Control the behaviour of a WebView.

Settings can be applied to a WebView to control text charset, color, font sizes, printing mode, script support, loading of images and various other things on a WebView. After creation, a Settings object contains default settings.

// Disable JavaScript
WebKitSettings *settings = webkit_web_view_group_get_settings (my_view_group);
webkit_settings_set_enable_javascript (settings, FALSE);

Constructors#

class Settings

classmethod new() → Settings#

Creates a new Settings instance with default values.

It must be manually attached to a WebView. See also new_with_settings().

Methods#

class Settings

apply_from_key_file(key_file: KeyFile, group_name: str) → bool#

Reads the contents of the given group_name from the given key_file and apply the value of each key/value to the corresponding property on the settings.

Value types have to match with the corresponding setting property type and the group keys have to match existing setting property names. If those conditions are not met, the function will return False.

Supported value types are strings (unquoted), booleans (0, 1, true, false) and unsigned integers.

Added in version 2.46.

Parameters:

key_file – a KeyFile
group_name – Name of the group to read from key_file

classmethod font_size_to_pixels(points: int) → int#

Properties#

class Settings

props.allow_file_access_from_file_urls: bool#: Whether file access is allowed from file URLs. By default, when something is loaded in a WebView using a file URI, cross origin requests to other file resources are not allowed. This setting allows you to change that behaviour, so that it would be possible to do a XMLHttpRequest of a local file, for example.

Added in version 2.10.

props.allow_modal_dialogs: bool#: Determine whether it’s allowed to create and run modal dialogs from a WebView through JavaScript with <function>window.showModalDialog</function>. If it’s set to False, the associated WebView won’t be able to create new modal dialogs, so not even the WebView::create signal will be emitted.

props.allow_top_navigation_to_data_urls: bool#: Whether or not the top frame is allowed to navigate to data URLs. It is disabled by default due to the risk it poses when loading untrusted URLs, with data URLs being used in scamming and phishing attacks. In contrast, a scenario where it could be enabled could be an app that embeds a WebView and you have control of the pages being show instead of a generic browser.

Added in version 2.28.

props.allow_universal_access_from_file_urls: bool#: Whether or not JavaScript running in the context of a file scheme URL should be allowed to access content from any origin. By default, when something is loaded in a WebView using a file scheme URL, access to the local file system and arbitrary local storage is not allowed. This setting allows you to change that behaviour, so that it would be possible to use local storage, for example.

Added in version 2.14.

props.auto_load_images: bool#: Determines whether images should be automatically loaded or not. On devices where network bandwidth is of concern, it might be useful to turn this property off.

props.cursive_font_family: str#: The font family used as the default for content using a cursive font.

props.default_charset: str#: The default text charset used when interpreting content with an unspecified charset.

props.default_font_family: str#: The font family to use as the default for content that does not specify a font.

props.default_monospace_font_size: int#: The default font size in pixels to use for content displayed in monospace font if no font size is specified.

props.disable_web_security: bool#

Enable or disable support for Web Security on pages.

This setting disables the same-origin policy, allowing every website full control over all other websites. This is for use in special environments where you wish to disable all security and allow websites to hack each other. It is impossible to use this setting securely.

Added in version 2.40.

props.draw_compositing_indicators: bool#: Whether to draw compositing borders and repaint counters on layers drawn with accelerated compositing. This is useful for debugging issues related to web content that is composited with the GPU.

props.enable_2d_canvas_acceleration: bool#: Enable or disable 2D canvas acceleration. If this setting is enabled, the 2D canvas will be accelerated even if Skia CPU is used for rendering. However, the canvas can be unaccelerated even when this setting is enabled, for other reasons like its size or when willReadFrequently property is used.

Added in version 2.46.

props.enable_back_forward_navigation_gestures: bool#: Enable or disable horizontal swipe gesture for back-forward navigation.

Added in version 2.24.

props.enable_caret_browsing: bool#: Whether to enable accessibility enhanced keyboard navigation.

props.enable_developer_extras: bool#: Determines whether or not developer tools, such as the Web Inspector, are enabled.

Deprecated since version 2.48: Please do not use it in newly written code

props.enable_encrypted_media: bool#

Enable or disable support for Encrypted Media API on pages. EncryptedMedia is an experimental JavaScript API for playing encrypted media in HTML. This property will only work as intended if the EncryptedMedia feature is enabled at build time with the ENABLE_ENCRYPTED_MEDIA flag.

See https://www.w3.org/TR/encrypted-media/

Added in version 2.20.

props.enable_fullscreen: bool#: 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/

props.enable_html5_database: bool#: Whether to enable HTML5 client-side SQL database support (IndexedDB).

props.enable_html5_local_storage: bool#

Whether to enable HTML5 local storage support. Local storage provides simple synchronous storage access.

HTML5 local storage specification is available at http://dev.w3.org/html5/webstorage/.

props.enable_hyperlink_auditing: bool#

Determines whether or not hyperlink auditing is enabled.

The hyperlink auditing specification is available at http://www.whatwg.org/specs/web-apps/current-work/multipage/links.html``hyperlink``-auditing.

Deprecated since version 2.50: Please do not use it in newly written code

props.enable_javascript: bool#: Determines whether or not JavaScript executes within a page.

Added in version 2.26.

props.enable_media_capabilities: bool#

Enable or disable support for MediaCapabilities on pages. This specification intends to provide APIs to allow websites to make an optimal decision when picking media content for the user. The APIs will expose information about the decoding and encoding capabilities for a given format but also output capabilities to find the best match based on the device’s display.

Added in version 2.22.

props.enable_media_stream: bool#

Enable or disable support for MediaStream on pages. MediaStream is an experimental proposal for allowing web pages to access audio and video devices for capture.

Deprecated since version 2.44: Please do not use it in newly written code

props.enable_page_cache: bool#: 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/

props.enable_resizable_text_areas: bool#: Determines whether or not text areas can be resized.

props.enable_site_specific_quirks: bool#: Whether to turn on site-specific quirks. Turning this on will tell WebKit to use some site-specific workarounds for better web compatibility. For example, older versions of MediaWiki will incorrectly send to WebKit a CSS file with KHTML workarounds. By turning on site-specific quirks, WebKit will special-case this and other cases to make some specific sites work.

props.enable_smooth_scrolling: bool#: Enable or disable smooth scrolling.

props.enable_spatial_navigation: bool#: Whether to enable 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. For example, if an user presses the Right key, heuristics determine whether there is an element they might be trying to reach towards the right, and if there are multiple elements, which element they probably wants.

Added in version 2.4.

props.enable_tabs_to_links: bool#: Determines whether the tab key cycles through the elements on the page. When this setting is enabled, users will be able to focus the next element in the page by pressing the tab key. If the selected element is editable, then pressing tab key will insert the tab character.

props.enable_webaudio: bool#

Enable or disable support for WebAudio on pages. WebAudio is an API for processing and synthesizing audio in web applications

props.enable_webgl: bool#: Enable or disable support for WebGL on pages. WebGL enables web content to use an API based on OpenGL ES 2.0.
