Hi, initially I've considered implementation of lazy-loading in playlistfiles, but there is a problem with constant methods. For example: virtual method Playlist::name() const. In case of XSPFPlaylist it calls method XSPFPlaylist::title(), but to get title you need to load playlist, thereore title() can not be a constant method. - Tatjana ----------------------------------------------------------- This is an automatically generated e-mail.
