Tassos,

Can you give me an example or point me to an example of what you mean?
I've only ever seen the loop done the way I had it.

Also, is there a way to force the sizes to update then?  I have 2
functions in my class containing some widgets, one that changes the
sizes and one that needs to read to changed sizes, and I need to make
sure the current sizes are the correct ones.

Thanks,
Ryan
