### Class

# WebKit2 WebContext

#### Description [src]

    class WebKit2.WebContext : GObject.Object
    {
      WebKitWebContextPrivate* priv
    }

Manages aspects common to all `WebKitWebView`s

The `WebKitWebContext` manages all aspects common to all `WebKitWebView`s.

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.

##### Methods inherited from GObject (43)

Please see GObject for a full list of methods.

#### Properties

###### WebKit2.WebContext:local-storage-directory

The directory where local storage data will be saved.

deprecated: 2.10. since: 2.8

###### WebKit2.WebContext:memory-pressure-settings

The `WebKitMemoryPressureSettings` applied to the web processes created by this context.

since: 2.34

###### WebKit2.WebContext:process-swap-on-cross-site-navigation-enabled

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

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. The other, less optimal, approach is to globally set the TZ environment variable in the process before creating the context. However this approach might not be very convenient and can have side-effects in your application.

since: 2.38

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

Whether to use system appearance for rendering scrollbars.

deprecated: 2.46 since: 2.30

###### WebKit2.WebContext:website-data-manager

The `WebKitWebsiteDataManager` associated with this context.

since: 2.10

#### 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.

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.

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().

since: 2.4

###### WebKit2.WebContext::user-message-received

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

since: 2.28

##### Signals inherited from GObject (1)

###### GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
