Hi
I have a play-method in my own stream-player and it works:
def node_clicked(self, widget, item):
def play_uri(self, station):
# We already know the real URL of the playable audio stream, no
# need to query the resource manager
# get player and start playing
player =
self.frontend.retrieve_controllers('/poblesec/music_player')[0]
player.player.play_model(station)
main = self.frontend.retrieve_controllers('/poblesec')[0]
main.show_music_player()
self.stop_loading_animation()
pdb.set_trace()
if isinstance(item, Action):
item.run()
elif isinstance(item, PlayableModel):
play_uri(self, item)
It works fine but if there are problems with the stream it will hang for a
while, so I thought I could use a deferred, like:
def node_clicked(self, widget, item):
def play_uri(self, station):
# We already know the real URL of the playable audio stream, no
# need to query the resource manager
# get player and start playing
player =
self.frontend.retrieve_controllers('/poblesec/music_player')[0]
player.player.play_model(station)
main = self.frontend.retrieve_controllers('/poblesec')[0]
main.show_music_player()
self.stop_loading_animation()
pdb.set_trace()
if isinstance(item, Action):
item.run()
elif isinstance(item, PlayableModel):
dfr = defer.Deferred().addCallback(play_uri)
return dfr(self, item)
My problem is that I am not sure:
1) Do I create the deferred in the right manner?
2) How does the binding of the parameters happen?
3) Do I need to activate the deferred my self or will this happen by magic by
it self?
As
far as I can read the deferred can be compared to the .NET asynchronous
delegates or boost::thread. Boost::thread is much simpler but they
share the problem regarding binding variables.
Please help me fix the code!
Best Regards,
Kristian
