Prompt.performSync

glib.variant.Variant performSync(string windowId,  gio.cancellable.Cancellable cancellable,  glib.variant_type.VariantType returnType)

Runs a prompt and performs the prompting.

Returns a variant result if the prompt was completed and not dismissed. The type of result depends on the action the prompt is completing, and is defined in the Secret Service DBus API specification.

If window_id is non-null then it is used as an XWindow id on Linux. The API expects this id to be converted to a string using the `d` printf format. The Secret Service can make its prompt transient for the window with this id. In some Secret Service implementations this is not possible, so the behavior depending on this should degrade gracefully.

This method may block indefinitely and should not be used in user interface threads.

Parameters

`windowId`	string form of XWindow id for parent window to be transient for
`cancellable`	optional cancellation object
`returnType`	the variant type of the prompt result

Returns

null if the prompt was dismissed or an error occurred

Throws

[ErrorWrap]
