[Pyobjc-dev] How to implement a protocol?

[Jiva D. <ji...@de...>]

I am trying to set up a toolbar for my app.  So I am implementing the 
delegate methods for that.  One of the delegate methods I need to 
implement is this:

- (NSToolbarItem *)toolbar:(NSToolbar *)toolbar 
itemForItemIdentifier:(NSString *)itemIdentifier 
willBeInsertedIntoToolbar:(BOOL)flag;

How do I write this as a python method to implement this?  Right now, 
it's complaining that I haven't implemented all the methods for this.  
I suspect this is the one it doesn't like.
