>From what I gather from having recently been trying to read up on Qt:

- The newer verions of Qt actually use the real native widgets, unlike older 
versions of Qt.

- MOC is a preprocessor packaged with Qt. Qt uses this concept of "signals" 
and "sockets", which are apperently just like using a delegate collection 
(ie, like "(void delegate())[]" or C#/WinForm's event system, or something 
like that). Problem is, the original version of Qt is made for C++, which 
doesn't have proper delegates (at least not last I checked). So they hacked 
it together using a special preprocessor for C++ code.
