What is QtQR?
QtQR is an open-source library that provides QR code generation and scanning capabilities for applications built with the Qt framework. It is designed to be easy to integrate into existing Qt-based projects to add QR code functionality.
Some key features of QtQR include:
- Generating QR codes from text, URLs, contact data, WiFi login details, and more

- Customizable options like QR code size, error correction level, margins, and color
- Pure Qt implementation for cross-platform support on desktop, mobile, and embedded Qt applications
- Permissive open-source MIT license allowing modification and integration into commercial applications
QtQR takes advantage of Qt's modular architecture and extensive library of classes and functions for building performant and responsive applications across platforms. Integrating QtQR can significantly reduce development time and effort compared to building custom QR code functionality.
