If you mean that you can't do:
Qt Code:
  1. QSettings settings(...);
  2. settings.setValue("some\thing", 7);
To copy to clipboard, switch view to plain text mode 
...then QSettings has nothing to do with that. It's the compiler that treats the backslash as an escape character. If you did:
Qt Code:
  1. QSettings settings(...);
  2. settings.setValue("some\\thing", 7);
To copy to clipboard, switch view to plain text mode 
...it should work correctly.
