Properties

  "client-cache"             EClientCache*         : Read / Write / Construct Only

Description

EClientSelector extends the functionality of ESourceSelector by utilizing an EClientCache to display status information about the backends associated with the displayed data sources.

Details

struct EClientSelector

struct EClientSelector;

e_client_selector_new ()

GtkWidget *         e_client_selector_new               (EClientCache *client_cache,
                                                         const gchar *extension_name);

Displays a list of sources having an extension named extension_name, along with status information about the backends associated with them. The sources are grouped by backend or groupware account, which are described by the parent source.

client_cache :

an EClientCache

extension_name :

the name of an ESource extension

Returns :

a new EClientSelector

e_client_selector_ref_client_cache ()

EClientCache *      e_client_selector_ref_client_cache  (EClientSelector *selector);

Returns the EClientCache passed to e_client_selector_new().

The returned EClientCache is referenced for thread-safety and must be unreferenced with g_object_unref() when finished with it.

selector :

an EClientSelector

Returns :

an EClientCache

e_client_selector_get_client_sync ()

EClient *           e_client_selector_get_client_sync   (EClientSelector *selector,
                                                         ESource *source,
                                                         gboolean call_allow_auth_prompt,
                                                         guint32 wait_for_connected_seconds,
                                                         GCancellable *cancellable,
                                                         GError **error);

Obtains a shared EClient instance for source, or else creates a new EClient instance to be shared.

The "extension-name" property determines the type of EClient to obtain. See e_client_cache_get_client_sync() for a list of valid extension names.

If a request for the same source and "extension-name" is already in progress when this function is called, this request will "piggyback" on the in-progress request such that they will both succeed or fail simultaneously.

The wait_for_connected_seconds argument had been added since 3.16, to let the caller decide how long to wait for the backend to fully connect to its (possibly remote) data store. This is required due to a change in the authentication process, which is fully asynchronous and done on the client side, while not every client is supposed to response to authentication requests. In case the backend will not connect within the set interval, then it is opened in an offline mode. A special value -1 can be used to not wait for the connected state at all.

Unreference the returned EClient with g_object_unref() when finished with it. If an error occurs, the function will set error and return NULL.

selector :

an ESourceSelector

source :

an ESource

call_allow_auth_prompt :

whether call allow-auth-prompt on the source first

wait_for_connected_seconds :

timeout, in seconds, to wait for the backend to be fully connected

cancellable :

optional GCancellable object, or NULL

error :

return location for a GError, or NULL

Returns :

an EClient, or NULL

e_client_selector_get_client ()

void                e_client_selector_get_client        (EClientSelector *selector,
                                                         ESource *source,
                                                         gboolean call_allow_auth_prompt,
                                                         guint32 wait_for_connected_seconds,
                                                         GCancellable *cancellable,
                                                         GAsyncReadyCallback callback,
                                                         gpointer user_data);

Asynchronously obtains a shared EClient instance for source, or else creates a new EClient instance to be shared.

The "extension-name" property determines the type of EClient to obtain. See e_client_cache_get_client_sync() for a list of valid extension names.

If a request for the same source and "extension-name" is already in progress when this function is called, this request will "piggyback" on the in-progress request such that they will both succeed or fail simultaneously.

The wait_for_connected_seconds argument had been added since 3.16, to let the caller decide how long to wait for the backend to fully connect to its (possibly remote) data store. This is required due to a change in the authentication process, which is fully asynchronous and done on the client side, while not every client is supposed to response to authentication requests. In case the backend will not connect within the set interval, then it is opened in an offline mode. A special value -1 can be used to not wait for the connected state at all.

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

selector :

an ESourceSelector

source :

an ESource

call_allow_auth_prompt :

whether call allow-auth-prompt on the source first

wait_for_connected_seconds :

timeout, in seconds, to wait for the backend to be fully connected

cancellable :

optional GCancellable object, or NULL

callback :

a GAsyncReadyCallback to call when the request is satisfied

user_data :

data to pass to the callback function

e_client_selector_get_client_finish ()

EClient *           e_client_selector_get_client_finish (EClientSelector *selector,
                                                         GAsyncResult *result,
                                                         GError **error);

Finishes the operation started with e_client_selector_get_client().

Unreference the returned EClient with g_object_unref() when finished with it. If an error occurred, the function will set error and return NULL.

selector :

an EClientSelector

result :

a GAsyncResult

error :

return location for a GError, or NULL

Returns :

an EClient, or NULL

e_client_selector_ref_cached_client ()

EClient *           e_client_selector_ref_cached_client (EClientSelector *selector,
                                                         ESource *source);

Returns a shared EClient instance for source and the value of "extension-name" if such an instance is already cached, or else NULL. This function does not create a new EClient instance, and therefore does not block.

The returned EClient is referenced for thread-safety and must be unreferenced with g_object_unref() when finished with it.

selector :

an EClientSelector

source :

an ESource

Returns :

an EClient, or NULL

e_client_selector_ref_cached_client_by_iter ()

EClient *           e_client_selector_ref_cached_client_by_iter
                                                        (EClientSelector *selector,
                                                         GtkTreeIter *iter);

Returns a shared EClient instance for the ESource in the tree model row pointed to by iter and the value of "extension-name" if such an instance is already cached, or else NULL. This function does not create a new EClient instance, and therefore does not block.

The returned EClient is referenced for thread-safety and must be unreferenced with g_object_unref() when finished with it.

selector :

an EClientSelector

iter :

a GtkTreeIter

Returns :

an EClient, or NULL

e_client_selector_is_backend_dead ()

gboolean            e_client_selector_is_backend_dead   (EClientSelector *selector,
                                                         ESource *source);

Returns TRUE if an EClient instance for source and the value of "extension-name" was recently discarded after having emitted a "backend-died" signal, and a replacement EClient instance has not yet been created.

selector :

an EClientSelector

source :

an ESource

Returns :

whether the backend for source died
