Answer 1

Another way to achieve the same thing is by cheking similar code:

GObject:

GLib:

Vala:

http://en.wikipedia.org/wiki/Vala_%28programming_language%29

Those guys wanted to work with a object and class oriented programming language, but "C++", didn't fit their requisites. Then , they took "plain C", and simulate objects withn records & pointers, including Virtual Method Tables. Eventually got a similar language called "Vala", their own "C++" alike language (with their own V.M.T.).
