Which does an extremely miserable job!  In fact, Qt is just one of the worst
GUI abstraction layers that exist (I am sure that is why it is so popular!).
It does not abstract most of the GUI elements at all, it just draws them on
its own.  Apart from that, Qt is hardly a good example for use of C++.  Its
signal implementation is a perfect example.  As is is non-existent
thread-safety - even if a native API used is fully thread-safe, Qt in
general is not thread-safe.  And its OpenGL widget for Windows is full of
very obvious bugs (also this is only available with the expensive commercial
code license); even M$ sample code shows how to properly create a correct
Z-buffered contexts.
