Re: how to break the loop

I'd suggest that unless you really know what you're doing, consider 
processEvents() method non-existent. It will avoid potential problems later 
as your code grows.

It'll also force you to either re-evaluate your loop design, or to move the 
non-gui loop over to another thread. It's a worthwhile exercise, at least to 
me it was. In the Qt headers that I'm using in my projects, I've simply made 
processEvents() protected.
