Re: [Pyobjc-dev] PyObjC speech

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

Hi,

Thanks for your quick reply!

I *did* in fact make that signature up. I was trying to go by the 
documentation of objc.selector, hoping that the values for 
argumentTypes were equal to those in the method signature. Turns out 
they weren't.

I'm posting my correct example. Note that I'm running this from an 
appcontext already. (PythonIDE, and in the future, DrawBot) This one 
waits nicely for a speech item to finish before starting on the next 
one.

Again, many thanks,

Frederik
