const gchar *
goa_provider_get_provider_type (GoaProvider *provider
);
Gets the type of provider
.
This is a pure virtual method - a subclass must provide an implementation.
gchar * goa_provider_get_provider_name (GoaProvider *provider
,GoaObject *object
);
Gets a name for provider
and object
that is suitable for display
in an user interface. The returned value may depend on object
(if
it's not NULL
) - for example, hosted accounts might return a
different name.
This is a pure virtual method - a subclass must provide an implementation.
GIcon * goa_provider_get_provider_icon (GoaProvider *provider
,GoaObject *object
);
Gets an icon for provider
and object
that is suitable for display
in an user interface. The returned value may depend on object
-
for example, hosted accounts might return a different icon.
This is a virtual method with a default implementation that returns
a GThemedIcon with fallbacks constructed from the name
goa-account-TYPE
where TYPE
is the return value of goa_provider_get_provider_type()
.
gboolean goa_provider_build_object (GoaProvider *provider
,GoaObjectSkeleton *object
,GKeyFile *key_file
,const gchar *group
,GError **error
);
This method is called when construction account GoaObject from configuration data - it basically provides a way to add provider-specific information.
The passed in object
will have a GoaAccount interface
set. Implementations should validate and use data from key_file
to
add more interfaces to object
.
Note that this may be called on already exported objects - for example on configuration files reload.
This is a pure virtual method - a subclass must provide an implementation.

GoaObject * goa_provider_add_account (GoaProvider *provider
,GoaClient *client
,GtkDialog *dialog
,GtkBox *vbox
,GError **error
);
This method brings up the user interface necessary to create a new
account on client
of the type for provider
, interacts with the
user to get all information needed and creates the account.
The passed in dialog
widget is guaranteed to be visible with vbox
being empty and the only visible widget in dialog
's content
area. The dialog has exactly one action widget, a cancel button
with response id GTK_RESPONSE_CANCEL. Implementations are free to
add additional action widgets, as needed.
If an account was successfully created, a GoaObject for the
created account is returned. If dialog
is dismissed, NULL
is
returned and error
is set to GOA_ERROR_DIALOG_DISMISSED
. If an
account couldn't be created then error
is set.
The caller will always show an error dialog if error
is set unless
the error is GOA_ERROR_DIALOG_DISMISSED
.
Implementations should run the default main loop while
interacting with the user and may do so using e.g. gtk_dialog_run()
on dialog
.
This is a pure virtual method - a subclass must provide an implementation.

The GoaObject for the created account (must be relased
with g_object_unref()
) or NULL
if error
is set.
gboolean goa_provider_refresh_account (GoaProvider *provider
,GoaClient *client
,GoaObject *object
,GtkWindow *parent
,GError **error
);
This method brings up the user interface necessary for refreshing
the credentials for the account specified by object
. This
typically involves having the user log in to the account again.
Implementations should use parent
(unless NULL
) as the transient
parent of any created windows/dialogs.
Implementations should run the default main loop while interacting with the user.
This is a pure virtual method - a subclass must provide an implementation.

void goa_provider_show_account (GoaProvider *provider
,GoaClient *client
,GoaObject *object
,GtkBox *vbox
,GtkTable *table
);
Method used to add widgets in the control panel for the account
represented by object
.
This is a virtual method with an implementation that (currently)
does nothing. A subclass should chain up (before adding their own
widgets to vbox
and table
) if they want to expose such
functionality.

gboolean goa_provider_store_credentials_sync (GoaProvider *provider
,GoaObject *object
,GVariant *credentials
,GCancellable *cancellable
,GError **error
);
Stores credentials
for identity
in the key-ring. If credentials
is floating, it is consumed.
The calling thread is blocked while waiting for a reply.
This is a convenience method (not virtual) that subclasses can use.

Looks up credentials in the keyring for identity

with goa_provider_store_credentials()
.

void goa_provider_ensure_credentials (GoaProvider *provider
,GoaObject *object
,GCancellable *cancellable
,GAsyncReadyCallback callback
,gpointer user_data
);
Ensures that credentials for object
are still valid.
When the result is ready, callback
will be called in the the goa_provider_ensure_credentials_finish()
to get the result
of the operation.
This is a virtual method where the default implementation simply
returns the GOA_ERROR_NOT_SUPPORTED
error. A subclass may provide
another implementation.

guint
goa_provider_get_credentials_generation
(GoaProvider *provider
);
Gets the generation of credentials being used for the provider.
Implementations should bump this number when changes are introduced that may render existing credentials unusable.
For example, if an additional scope is requested (e.g. access to contacts data) while obtaining credentials, then this number needs to be bumped since existing credentials are not good for the added scope.
This is a virtual method where the default implementation returns 0.

extension
point and returns a newly created GoaProvider for each
provider type encountered.
