enum WebKitFaviconDatabaseError

typedef enum {

} WebKitFaviconDatabaseError;

Enum values used to denote the various errors related to the WebKitFaviconDatabase.

WEBKIT_FAVICON_DATABASE_ERROR_NOT_INITIALIZED

 The WebKitFaviconDatabase has not been initialized yet

WEBKIT_FAVICON_DATABASE_ERROR_FAVICON_NOT_FOUND

 There is not an icon available for the requested URL

WEBKIT_FAVICON_DATABASE_ERROR_FAVICON_UNKNOWN

 There might be an icon for the requested URL, but its data is unknown at the moment

webkit_favicon_database_get_favicon ()

void                webkit_favicon_database_get_favicon (WebKitFaviconDatabase *database,
                                                         const gchar *page_uri,

                                                         gpointer user_data);

Asynchronously obtains a cairo_surface_t of the favicon for the given page URI. It returns the cached icon if it's in the database asynchronously waiting for the icon to be read from the database.

This is an asynchronous method. When the operation is finished, callback will be invoked. You can then call webkit_favicon_database_get_favicon_finish() to get the result of the operation.

database :

 a WebKitFaviconDatabase

page_uri :

 URI of the page for which we want to retrieve the favicon

cancellable :

 A GCancellable or NULL. [allow-none]

callback :

 A GAsyncReadyCallback to call when the request is satisfied or NULL if you don't care about the result. [scope async]

user_data :

 The data to pass to callback. [closure]

                                                         GError **error);

Finishes an operation started with webkit_favicon_database_get_favicon().

database :

 a WebKitFaviconDatabase

result :

 A GAsyncResult obtained from the GAsyncReadyCallback passed to webkit_favicon_database_get_favicon()

error :

 Return location for error or NULL. [allow-none]

Returns :

 a new reference to a cairo_surface_t, or NULL in case of error. [transfer full]

Obtains the URI of the favicon for the given page_uri.

database :

 a WebKitFaviconDatabase

page_uri :

 URI of the page containing the icon

Returns :

 a newly allocated URI for the favicon, or NULL if the database doesn't have a favicon for page_uri.

Signal Details

The "favicon-changed" signal

void                user_function                      (WebKitFaviconDatabase *database,
                                                        gchar                 *page_uri,
                                                        gchar                 *favicon_uri,
                                                        gpointer               user_data)        : Run Last

This signal is emitted when the favicon URI of page_uri has been changed to favicon_uri in the database. You can connect to this signal and call webkit_favicon_database_get_favicon() to get the favicon. If you are interested in the favicon of a WebKitWebView it's easier to use the "favicon" property. See webkit_web_view_get_favicon() for more details.

database :

 the object on which the signal is emitted

page_uri :

 the URI of the Web page containing the icon

favicon_uri :

 the URI of the favicon

user_data :

 user data set when the signal handler was connected.
