webkit_web_context_get_cache_model ()

WebKitCacheModel
webkit_web_context_get_cache_model (WebKitWebContext *context);

Returns the current cache model. For more information about this value check the documentation of the function webkit_web_context_set_cache_model().

webkit_web_context_set_cache_model ()

void
webkit_web_context_set_cache_model (WebKitWebContext *context,
                                    WebKitCacheModel cache_model);

Specifies a usage model for WebViews, which WebKit will use to determine its caching behavior. All web views follow the cache model. This cache model determines the RAM and disk space to use for caching previously viewed content .

Research indicates that users tend to browse within clusters of documents that hold resources in common, and to revisit previously visited documents. WebKit and the frameworks below it include built-in caches that take advantage of these patterns, substantially improving document load speed in browsing situations. The WebKit cache model controls the behaviors of all of these caches, including various WebCore caches.

Browsers can improve document load speed substantially by specifying WEBKIT_CACHE_MODEL_WEB_BROWSER. Applications without a browsing interface can reduce memory usage substantially by specifying WEBKIT_CACHE_MODEL_DOCUMENT_VIEWER. The default value is WEBKIT_CACHE_MODEL_WEB_BROWSER.

webkit_web_context_clear_cache ()

void
webkit_web_context_clear_cache (WebKitWebContext *context);

Clears all resources currently cached. See also webkit_web_context_set_cache_model().

                                 const gchar *uri);

Requests downloading of the specified URI string. The download operation will not be associated to any WebKitWebView, if you are interested in starting a download from a particular WebKitWebView use webkit_web_view_download_uri() instead.

webkit_web_context_get_cookie_manager ()

WebKitCookieManager *
webkit_web_context_get_cookie_manager (WebKitWebContext *context);

webkit_web_context_get_favicon_database ()

                               (WebKitWebContext *context);

Get the WebKitFaviconDatabase associated with context .

To initialize the database you need to call webkit_web_context_set_favicon_database_directory().

webkit_web_context_set_favicon_database_directory ()

void
webkit_web_context_set_favicon_database_directory
                               (WebKitWebContext *context,
                                const gchar *path);

Set the directory path to be used to store the favicons database for context on disk. Passing NULL as path means using the default directory for the platform (see g_get_user_data_dir()).

Calling this method also means enabling the favicons database for its use from the applications, so that's why it's expected to be called only once. Further calls for the same instance of WebKitWebContext won't cause any effect.

webkit_web_context_get_favicon_database_directory ()

This function will always return the same path after having called webkit_web_context_set_favicon_database_directory() for the first time.

webkit_web_context_get_security_manager ()

WebKitSecurityManager *
webkit_web_context_get_security_manager
                               (WebKitWebContext *context);

                                gpointer user_data);

Asynchronously get the list of installed plugins.

When the operation is finished, callback will be called. You can then call webkit_web_context_get_plugins_finish() to get the result of the operation.

webkit_web_context_get_plugins_finish ()

void
webkit_web_context_set_spell_checking_languages
                               (WebKitWebContext *context,
                                const gchar * const *languages);

Set the list of spell checking languages to be used for spell checking.

The locale string typically is in the form lang_COUNTRY, where lang is an ISO-639 language code, and COUNTRY is an ISO-3166 country code. For instance, sv_FI for Swedish as written in Finland or pt_BR for Portuguese as written in Brazil.

You need to call this function with a valid list of languages at least once in order to properly enable the spell checking feature in WebKit.

webkit_web_context_set_preferred_languages ()

void
webkit_web_context_set_preferred_languages
                               (WebKitWebContext *context,
                                const gchar * const *languages);

Set the list of preferred languages, sorted from most desirable to least desirable. The list will be used to build the "Accept-Language" header that will be included in the network requests started by the WebKitWebContext.

                                const gchar *directory);

Set the directory where WebKit will look for Web Extensions. This method must be called before loading anything in this context, otherwise it will not have any effect. You can connect to “initialize-web-extensions” to call this method before anything is loaded.

Set the directory where disk cache files will be stored This method must be called before loading anything in this context, otherwise it will not have any effect.

Note that this method overrides the directory set in the WebKitWebsiteDataManager, but it doesn't change the value returned by webkit_website_data_manager_get_disk_cache_directory() since the WebKitWebsiteDataManager is immutable.

webkit_web_context_allow_tls_certificate_for_host ()

void
webkit_web_context_allow_tls_certificate_for_host
                               (WebKitWebContext *context,

webkit_web_context_get_process_model ()

WebKitProcessModel
webkit_web_context_get_process_model (WebKitWebContext *context);

Returns the current process model. For more information about this value see webkit_web_context_set_process_model().

Since: 2.4

webkit_web_context_set_process_model ()

void
webkit_web_context_set_process_model (WebKitWebContext *context,
                                      WebKitProcessModel process_model);

Specifies a process model for WebViews, which WebKit will use to determine how auxiliary processes are handled. The default setting (WEBKIT_PROCESS_MODEL_SHARED_SECONDARY_PROCESS) is suitable for most applications which embed a small amount of WebViews, or are used to display documents which are considered safe — like local files.

Applications which may potentially use a large amount of WebViews —for example a multi-tabbed web browser— may want to use WEBKIT_PROCESS_MODEL_MULTIPLE_SECONDARY_PROCESSES, which will use one process per view most of the time, while still allowing for web views to share a process when needed (for example when different views interact with each other). Using this model, when a process hangs or crashes, only the WebViews using it stop working, while the rest of the WebViews in the application will still function normally.

This method **must be called before any other functions**, as early as possible in your application. Calling it later will make your application crash.

Since: 2.4

WebKitURISchemeRequestCallback ()

void
(*WebKitURISchemeRequestCallback) (WebKitURISchemeRequest *request,
                                   gpointer user_data);

Type definition for a function that will be called back when an URI request is made for a user registered URI scheme.

webkit_web_context_register_uri_scheme ()

void

                                const gchar *scheme,
                                WebKitURISchemeRequestCallback callback,
                                gpointer user_data,
                                GDestroyNotify user_data_destroy_func);

Register scheme in context , so that when an URI request with scheme is made in the WebKitWebContext, the WebKitURISchemeRequestCallback registered will be called with a WebKitURISchemeRequest. It is possible to handle URI scheme requests asynchronously, by calling g_object_ref() on the WebKitURISchemeRequest and calling webkit_uri_scheme_request_finish() later when the data of the request is available or webkit_uri_scheme_request_finish_error() in case of error.
