Creating a GUI window in C

This program demonstrates how to create a basic GUI window in C without any external modules.

Prerequisites

• C compiler (GCC, Clang, etc.).
• For Windows: MinGW or Visual Studio (if using Visual Studio, some modifications may be required).
• For Unix-based systems: Xlib development library.

How to build and run

Windows Open the command prompt and navigate to the directory containing the source code file main.c. Compile the code using

  gcc main.c -o main

Run the program using

  main.exe

Unix-based systems

Open the terminal and navigate to the directory containing the source code file

  main.c

Compile the code using

  gcc main.c -o main -lX11.

Run the program using

  ./main

How it works

The program uses conditional compilation to differentiate between Windows and Unix-based systems, as the method for creating GUI windows is different for each. On Windows, the program uses the Win32 API to register a window class, create a window, and enter a message loop. On Unix-based systems, the program uses Xlib to create a simple window, map it to the screen, and wait for a key press event.
