Coding a Graphical User Interface in C - from scratch
In this new self-contained project we'll be coding our own Windows system! We'll write a 2D graphics engine, we'll design a GUI and then we'll use our library to show real windows on the screen, control them with the mouse etc.
This project will run in a virtualized environment (easy to set up, I will show you) so the code runs equally well on top of Windows, Linux or Mac OS X.
PLEASE NOTE: You need to know the basics of C to follow along this project, but nothing else. We'll use additional components but that's 5% and you can just copy that stuff if you'd like. The code is freely available at the repo (watch below) and it will stay there for 4 days as usual.
Let us get going :)
