Implemented Interfaces

GDataPicasaWebFile implements GDataCommentable.

Includes

#include <gdata/services/picasaweb/gdata-picasaweb-file.h>

Description

GDataPicasaWebFile is a subclass of GDataEntry to represent a file (photo or video) in an album on Google PicasaWeb.

GDataPicasaWebFile implements GDataCommentable, allowing comments on files to be queried using gdata_commentable_query_comments(), new comments to be added to files using gdata_commentable_insert_comment() and existing comments to be deleted from files using gdata_commentable_delete_comment().

For more details of Google PicasaWeb's GData API, see the

online documentation.
