Return Value of ProtoSoupOverview's HitItem Message (1/6/97)
- Q: What is the meaning of the return value of
protoSoupOverview:HitItem(...)? I want to call the inherited method and use the return value to determine what action the system performed.
A: ProtoSoupOverview:HitItem(...) returns nil if it handled the tap and non-nil if it didn't handle the tap (the opposite meaning of the return value of protoOverview's HitItem method).
Note that the final NPG documentation implies that protoSoupOverview's HitItem is just like protoOverview's HitItem method; this is a mistake in the documentation.
