Opengl GUI, in C++

It seems that my test/welcome article has been successfully posted, not that anything could go wrong with a blogging service, especially not when owned and maintained by google :).

So today i will be posting my first, real, article. Its about a project i abandon a year ago, although i kinda stopped putting a lot of time into it even a year before that.

How could this be?
The answer to that question is rather easy to answer if you have ever taken a look at the code, its horrifying.
A year after abandoning the project i have decided to take a look again at the code, just for fun.
But suddenly i remembered why i quit.

I started coding random things, i had just finished reading "Aan de slag met C++" wich is a dutch book for learning the programming language C++, i had already bought myself a book about learning Opengl.

I have learned a lot by making this GUI, which basically involves 1 basic class which contains coordinates, size and other classes which inherit from it since coordinates and such can be reused.
As i have already said, i have learned a lot of it, but also put many hours into debugging it.
But as a beginner, you make beginner mistakes and since programming isnt exactly shallow curved, you keep making them for a long time.

The GUI was the only thing i have finished in that period of my life, other stuff i will post later this week.

This is the only watchable material i have of the GUI, on request i might undust the program and upload some more pics of it if people actually care :-).

#edit: the source code can be found here: http://code.google.com/p/openglengine/
(please do not try to learn from it :P)
