The playlist GUI (pykaroake.py) calls out to MakePlayer() in pykdb.py to
start the players. This in turn uses either pycdg.py, pykar.py or
pympg.py depending on the songfile type. All of these eventually make
use of InitPlayer() in pykmanager.py to initialise pygame if necessary.
You may find InitPlayer() is a useful place to do something like this.
That said, I don't know whether it is even possible to set the X display
in this way. I strongly suspect that it won't be possible to have the
same process utilising two different X displays (one for WxWidgets and
one for Pygmae), but I don't know what the rules are there with X. It
might be necessary to spawn a new process to handle the player windows
rather than run them as a thread within the existing process. It should
be possible to insert a different interface between the playlist and the
players such that two separate processes communicate using something
like a socket. You'd need to implement two-way communication such that
the playlist can tell the player process to play/pause etc. and when the
song finishes the player can callback to the playlist to notify it.
Hopefully the interface will be clean enough such that you can drop in a
replacement glue layer to handle the interprocess communication
If you're interested in taking this up I'd be happy to provide further
info on how it all fits together.
Kelvin.
