I do see a use for using a schema right there. Settings can be accessed
from all over the application. If you use QSettings or QConfiguration or
whatever for that directly, it means that everywhere you need a specific
value, you also need the default value. So, you end up duplicating the
default value to several places in the code, and it won't be easy to
find all occurrences either. If you define the defaults centrally, at
least you don't have that issue.
You like Qt?
