#### Declaration [src]

      GtkAlertDialog* self,

    )

#### Description [src]

Finishes the `gtk_alert_dialog_choose()` call.

Available since: 4.10

#### Parameters

`result`

  Type: `GAsyncResult`

  The result.

  The data is owned by the caller of the method.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the method if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `int`

The index of the button that was clicked, or -1 if the dialog was cancelled and `GtkAlertDialog:cancel-button` is not set.
