Thanks All for your replies. I think I have seen the error of my ways
regarding the size of my class. Since I had two classes that were so
hopelessly intertwined, I put them together into one and now I see that I could
indeed have done it instead with two or maybe three. The paradigm shift from
all data available at all times with all the globals you can eat to private
data has been a difficult one to make for me.
Regarding my final program, I tried to use Shark, but I believe I need a little
more experience and to take a look under the hood before it starts making sense
to me. So, I tried the same informal test with Text Edit and got similar
results, about 25% of my processor was used (where my program used 30%.) Text
Wrangler used about 50%. This leads me to three conclusions:
0. My code doesn't totally stink.
1. The Field Editor is very expensive to use.
2. 1GHz of G4 just doesn't go as far as it used to.
However, the learning experience has been a positive one and I really enjoy
working with Cocoa, even if the majority of Apple's documentation leaves me
scratching my head. I usually need to see concrete examples to understand how
the code works.
I doubt I will go back and fix my program to split the classes up. This is
like Mark VII on this program, the previous six dismantled and
reincorporated--I kept coding myself into a corner where only a global would
save me and I am just happy the accursed thing works. So, I will know that
much more about what I am doing with my next project. I think it will be with
graphics. OpenGL looks interesting. :)
Once again, thanks to all who took the time to read and reply.
