Hi,
Got it working! The problem was partly due to tiredness and partly due to a
misunderstanding about when layoutSubviews gets called.
If you look at the Street Scroller sample, you'll see that it has its content
"in-built", in fact it generate new content on the fly. The problem I had was
that the content (images in this case) needed to be loaded externally from a
URL or from a file. Once I figured out how to get the process going it was ok
and I did it without having to add code to the delegate which is always a good
thing.
Thanks a lot to everyone that helped.
All the Best
Dave
