Description

Code a GUI from scratch in C!"Build a 2D graphics engine & display custom windows in this epic 2-part tutorial. Subscribe now!"
Welcome to the "Code a GUI in C" project! In this self-contained tutorial, we're building a custom Windows-like system from the ground up. You'll learn to code a 2D graphics engine, design a graphical user interface (GUI), and display real windows on-screen with mouse controls—all in C! We'll run everything in a virtualized environment (works on Windows, Linux, or (Mac OSX), with easy setup instructions included).
What You'll LearnPart 1: Design the interface, code a 2D graphics engine from scratch, handling text, points, lines, and rectangles. Part 2: Parse the .BMP file format to draw pixel-perfect images for your GUI's window designs.
Prerequisites
Basic C knowledge is needed, but don't worry—additional components are minimal (just 5% of the project), and you can copy them if needed. The full source code is available for free at my code repo.
