When was the last time you typed

qlabel *l = new qlabel("hi");

and wondered why it doesn't compile? :)

the documentation lists the class names accordingly. There's no way around 
it, not even lowercase header files can prevent the compiler from complaining 
that qlineedit is not a known class name ;-)
