help about helix libraries

[Peter Krenesky]

Hi Waqas,

I'm the lead dev for the helix python api so i should be able to answer 
any questions you have about it.

The helix engine requires an application "pump" the engine to keep it 
going (like an old fashion well pump).  hxplay.run() continuously pumps 
the engine, blocking till the end of stream is reached. 

what you need to do is call hxplay.doevent() from within the activity 
mainloop.  this allows both pygtk and helix to run at the same time. 

    class Play():
        def idle_function(self):
            try:
                hxplay.doevent()
            except Exception, e:
                print e
            return True


you also need to set the idle function and remove it when the class is 
cleaned up:

    self.idlefunction = gobject.idle_add(self.idle_function)
