Neon Calc

A simple calculator built with C++ and Raylib, featuring a visual interface inspired by classic Windows desktop applications.

Overview

Neon Calc is a fully custom-rendered calculator UI. No GUI toolkit, no dependencies beyond Raylib itself. It reproduces the shadowed-button, beveled-panel look of early Windows software, complete with a dedicated "About" window launched as a separate process, and supports the four basic arithmetic operations.

Features

• Retro Windows-inspired interface (shadow/highlight beveled buttons, bordered visor)
• Basic arithmetic: addition, subtraction, multiplication, division
• Standalone "About" window launched as a separate process
• Custom font rendering (MS Sans Serif, Tahoma)
