Deprecatedobject_type: GTypea GObject.GType supporting Gio.AsyncInitable.
Deprecatedn_parameters: numberthe number of parameters in parameters
Deprecatedparameters: Parameterthe parameters to use to construct the object
Deprecatedio_priority: numberthe I/O priority of the operation
OptionalDeprecatedcancellable: Gio.Cancellableoptional Gio.Cancellable object, null to ignore.
OptionalDeprecatedcallback: AsyncReadyCallback<GType<unknown>>a Gio.AsyncReadyCallback to call when the initialization is finished
since 2.54: Use g_object_new_with_properties() and g_async_initable_init_async() instead. See GObject.Parameter for more information.
Helper function for constructing Gio.AsyncInitable object. This is similar to
g_object_newv()but also initializes the object asynchronously.When the initialization is finished,
callbackwill be called. You can then callg_async_initable_new_finish()to get the new object and check for any errors.
