The situation is such that I use a winapi mplayer and pass to it a 
gdk_window handle,
and next, when that player stops it sends an awfull winapi message in 
some crazy
winapi way, and I've almost broke my brains in an effort to get this 
message.
This add_filter method was designed to catch those messages, but how - 
no one
has wrote an example. As far as I could find in Google, Tor Lillquist 
had added this
filter in about gtk+ 2.2.x.
