You might also try working without bindings:

The Currency Converter section has two tutorials with and without
bindings.
thanks for that, I can't work without bindings, I'm solely trying to
build an interface for a quartz composer
composition. No actual objective c is being used.
There doesn't seem to be a way to create any controller type that can
be bound to a boolean and will return
true only while actually being pressed (instead of a toggle).
I can see this is probably because it violates Apple's HIG and you're
supposed
to use the event action model.
still it's a pain for me, I need just this sort of controller for
live performance type visual applications.
