Yes, outlets are pointer but you need to declare a pointer in your
header (NSButton myButton is not defining a pointer to a button,
NSButton* myButton is)
I gotcha. It's not "dummyView" but "NSBox" that takes the asterisk,
then. Thanks!
Look at the examples in the /Developer/Examples/InterfaceBuilder and
/Developer/Examples/Cocoa

Either that's not it or I'm not understanding you properly. I
shouldn't need the asterisk since the outlet (object) variables are
already pointers, right? I tried just adding an asterisk anyway,
and it didn't help.
A possible hint as to the nature of the problem: the compiler error
messages are "in file included from ToDoAppDelegate.m:2:". This
wouldn't have something to do with the way the various files import
each other, would it? The #import directive is supposed to prevent
that sort of problem, right? I'm afraid I don't know enough about
the compiler yet....
Thanks!
