a #GType supporting #GAsyncInitable.
the number of parameters in parameters
the parameters to use to construct the object
the [I/O priority][io-priority] of the operation
optional #GCancellable object, null to ignore.
a #GAsyncReadyCallback to call when the initialization is finished
Deprecated: Use gobject.object.ObjectG.newWithProperties and gio.async_initable.AsyncInitable.initAsync instead. See #GParameter for more information.
Helper function for constructing #GAsyncInitable object. This is similar to gobject.object.ObjectG.newv but also initializes the object asynchronously.
When the initialization is finished, callback will be called. You can then call gio.async_initable.AsyncInitable.newFinish to get the new object and check for any errors.
