Re: [Banshee-List] How to detect whether a track is skipped

[Chen Tao <pro711 gmail com>]

Hi,�

I connected�TrackInfo.PlaybackFinished event to my event handler, but the event handler is called only when a song is skipped. It's not called when a song plays to the end. That's quite weird. Is it because the song is streamed from the Internet?

Are there any other ways to detect whether a song is played to the end?

Thank you.

You might be able to use the TrackInfo.PlaybackFinished event,
especially if you're sub-classing TrackInfo. It will give you the
percentage of the track that was played.
See for example what is done for podcasts, to mark them as read :
