Re: [Pyobjc-dev] ScreenSaver Example

[Jason T. <cat...@ma...>]

The first error message "can't get principalClass for 
/Users/dinu/Library/Screen Savers/SillyBalls.saver" actually brings up 
an issue I had when creating the screensaver, because I was trying to 
get around using a nib file by specifying a principleClass. At the time 
it seemed like that should work...So, I am wondering if it is possible 
to get rid of the requirement of having to specify a nib file? I was 
told that Ronald would have something to say about this.

Thanks,
Jason T.
