Qt API conventions predate the Standard Library standardisation. Qt's style 
exists because -- quite by definition -- Qt developers think their style is 
better. Moreover, Qt is recognised for having a nice, easy-to-learn API, 
whereas the C++ Standard Library meets quite often the exact opposite reaction 
(yes, anecdotal evidence).

More to the point, Qt developers don't have to know the Standard Library. *I* 
don't and I don't have time or interest in learning it. You will always see me 
write a for-loop to fill something rather than use std::fill.

Qt users don't have to learn it either. If they read the Qt source code, they 
should understand it. They might do that because they were debugging their 
application and stepped into Qt to find out what's happening.
