Problems with "end" callback in Python

[James Simmons]

Lukas,

Thanks for sending me your code.  It works as advertised.  HOWEVER, I 
was unable to get the technique to work with my own program (which is 
attached).  As Hynek has discovered, there are conflicts between the 
pygtk event dispatcher and the thread used by speech-dispatcher.  If I 
try to let the event loop run at the same time as speech dispatcher's 
thread none of the callbacks are received.  If I do a wait loop after 
initiating speech, ALL of the callbacks are received, but it does no 
good because the highlighting of my text in the GTK control is not made 
visible until *after* the text is finished.  As you can see I've tried 
to let the gtk pending events be processed from within the loop but 
nothing happens.  Only the final word actually gets highlighted.

So it looks like for now the only thing that works is my 
one-word-at-a-time approach, as bad as that is.
