get_thumbnail_uri

Gets the URI of the thumbnail for the DocumentsDocument.

If no thumbnail exists for the document, null will be returned.

The thumbnail may then be downloaded using a DownloadStream.

<example> <title>Downloading a Document Thumbnail</title> <programlisting> GDataDocumentsService *service; const gchar *thumbnail_uri; GCancellable *cancellable; GdkPixbuf *pixbuf; GError *error = NULL;

service = get_my_documents_service (); thumbnail_uri = gdata_documents_document_get_thumbnail_uri (my_document); cancellable = g_cancellable_new ();

/<!-- -->* Prepare a download stream *<!-- -->/ download_stream = GDATA_DOWNLOAD_STREAM (gdata_download_stream_new ( GDATA_SERVICE (service), NULL, thumbnail_uri, cancellable));

/<!-- -->* Download into a new GdkPixbuf. This can be cancelled using 'cancellable'. *<!-- -->/ pixbuf = gdk_pixbuf_new_from_stream (G_INPUT_STREAM (download_stream), NULL, &error);

if (error != NULL) { /<!-- -->* Handle the error. *<!-- -->/ g_error_free (error); }

g_object_unref (download_stream); g_object_unref (cancellable);
