Hi all,

Are there any best practices for working with QSettings in larger 
projects with many settings?

In particular:
- How do you efficiently synchronize settings with widgets in an options 
- How do you efficiently detect changes made in an option dialog. (I 
have some options that need significant calculations after changing. 
These should only be triggered if the corresponding setting was actually 
- How do you access the settings in the source code? Always casting the 
QVariants seems a bit tedious but the alternative would be to have 
additional local variables (or members) for the values which you would 
have to maintain additionally.

Thanks in advance.
