You should really name your category. Something like: @interface NSObject (MyViewDelegate) Even better if you're targeting Leopard only is to use a formal
protocol, but with optional methods. e.g. @protocol MyViewDelegate
@optional
- (void)pointClicked:(NSPoint)point;

can implement to detect mouse clicks. I've put something like this
in the header file: // delegate method:
@interface NSObject ()
- (void)pointClicked:(NSPoint)point;
@end This is enough to prevent a "no -pointClicked: method found"
compiler warning. But is it the best way to do it? dkj
