[SOLVED] Getting values from Banshee-player's "EventChanged" signal.

[Osmo Maatta]

Re-hello,
and thank you very much.

I did exactly as instructed and the code works now very well.

$ echo "VOID:STRING,STRING,DOUBLE" > marshal.list

$ glib-genmarshal --prefix=marshal marshal.list --header > sample1.h
$ glib-genmarshal --prefix=marshal marshal.list --body > sample1.c

Then copied/pasted the relevant parts from sample1.[ch] to my code.

Learned something new today ;-)

ps. I will now bake the new code to
https://launchpad.net/~osmoma/+archive/rec-applet so it can be
controlled by media-players.

Thanks,
  Osmo Antero M (Moma)
