[Pyobjc-dev] PyObjC speech

[Frederik De B. <fre...@pa...>]

Let's talk speech!

I'm having trouble using the NSSpeechSynthesizer delegates. I believe 
it's a problem with delegates in general. They seem to crash the 
application. I'm posting the code here. The problem is when then speak 
command is invoked.

Can anybody please explain the correct way to use delegate methods in 
PyObjC? Is it important to implement all elements of the delegate? And 
is there anything on the net on the correct format for the signature?

Regards,

Frederik De Bleser
