Class

WebKit2WebContext

Description [src] 

class WebKit2.WebContext : GObject.Object {
  parent: GObject
}

Manages aspects common to all WebKitWebViews

The WebKitWebContext manages all aspects common to all WebKitWebViews.

You can define the WebKitCacheModel with webkit_web_context_set_cache_model(), depending on the needs of your application. You can access the WebKitSecurityManager to specify the behaviour of your application regarding security using webkit_web_context_get_security_manager().

It is also possible to change your preferred language or enable spell checking, using webkit_web_context_set_preferred_languages(), webkit_web_context_set_spell_checking_languages() and webkit_web_context_set_spell_checking_enabled().

You can use webkit_web_context_register_uri_scheme() to register custom URI schemes, and manage several other settings.

TLS certificate validation failure is now treated as a transport error by default. To handle TLS failures differently, you can connect to WebKitWebView::load-failed-with-tls-errors. Alternatively, you can use webkit_web_context_set_tls_errors_policy() to set the policy WEBKIT_TLS_ERRORS_POLICY_IGNORE; however, this is not appropriate for Internet applications.

Properties

WebKit2.WebContext:local-storage-directory

The directory where local storage data will be saved.

Available since: 2.8

Deprecated since: 2.10.

WebKit2.WebContext:memory-pressure-settings

Available since: 2.34

Whether swap Web processes on cross-site navigations is enabled.

Available since: 2.28

WebKit2.WebContext:time-zone-override

The timezone override for this web context. Setting this property provides a better alternative to configure the timezone information for all webviews managed by the WebContext.

Available since: 2.38

WebKit2.WebContext:use-system-appearance-for-scrollbars

Whether to use system appearance for rendering scrollbars.

Available since: 2.30

WebKit2.WebContext:website-data-manager

Signals

WebKit2.WebContext::automation-started

This signal is emitted when a new automation request is made. Note that it will never be emitted if automation is not enabled in context, see webkit_web_context_set_automation_allowed() for more details.

Available since: 2.18

WebKit2.WebContext::download-started

This signal is emitted when a new download request is made.

WebKit2.WebContext::initialize-notification-permissions

This signal is emitted when a WebKitWebContext needs to set initial notification permissions for a web process. It is emitted when a new web process is about to be launched, and signals the most appropriate moment to use webkit_web_context_initialize_notification_permissions(). If no notification permissions have changed since the last time this signal was emitted, then there is no need to call webkit_web_context_initialize_notification_permissions() again.

Available since: 2.16

WebKit2.WebContext::initialize-web-extensions

This signal is emitted when a new web process is about to be launched. It signals the most appropriate moment to use webkit_web_context_set_web_extensions_initialization_user_data() and webkit_web_context_set_web_extensions_directory().

Available since: 2.4

WebKit2.WebContext::user-message-received

This signal is emitted when a WebKitUserMessage is received from a WebKitWebExtension. You can reply to the message using webkit_user_message_send_reply().

Available since: 2.28

Signals inherited from GObject (1)
