Open Source C User Interface (UI) Software for Mac

A comprehensive software suite for reading barcodes. Supports EAN/UPC, Code 128, Code 39, Interleaved 2 of 5 and QR Code. Includes libraries and applications for decoding captured barcode images and using a video device (eg, webcam) as a barcode scanner.

See https://tkimg.sourceforge.net/ for a list of supported image formats.

Togl provides a platform independent Tk widget for using OpenGL rendering contexts.

AntTweakBar is a small and easy to use C/C++ library that allows programmers to quickly add a light and intuitive GUI into OpenGL or DirectX based programs to interactively tweak parameters on-screen. AntTweakBar works with Linux, Windows and OSX, and can be easily integrated with custom windowing system or with existing toolkits. Examples of integration with GLFW, SDL, GLUT, SFML and DirectX are provided. The AntTweakBar library mainly targets graphical applications that need a quick way to tune parameters (even in fullscreen mode) and see the result in real-time like 3D demos, games, prototypes, inline editors, debug facilities of weightier graphical applications, etc. The project is not maintained anymore but feel free to download and modify the source code to fit your needs or fix issues.

Converts bitmap file to c/c++ files (usefull for embedded systems with GUI). The color encoding is fully configurable (for example 16bit 5/6/5) and a "preview" bmp file is generated to show how much the picture is altered by the information reduction

F2IBuilder, is a generator of bitmap fonts, opensource and multiplatform, developed in Java language, according to the GPL. F2IBuilder, é um gerador de fontes bitmap, opensource e multiplataforma, desenvolvido em linguagem java, de acordo com a lice

Agar provides a base GUI framework and a standard set of widgets from which graphical applications can be built which run natively under X11, Windows, MacOS, SDL and others. It takes advantage of texture and GPU acceleration wherever available. Agar can also attach to an existing framebuffer, SDL or OpenGL context and operate as a self-contained window-manager. It includes a standard library of general-purpose widgets, and is also designed to be extended externally. New widgets can be implemented as part of an application or library. Complex user interface elements can be realized often in few lines of code. Agar is also extensible at the low-level. The low-level API is documented such that modular drivers can be written which enable Agar applications to work seamlessly under many platforms graphics systems without any change at the application level.

The Eiffel Windowing System is a small Eiffel library providing an SDL-based windowing system (and possibly other frontends in the future).

Flying Cow is a three-dimensional user interface for quickly seeking an item. It provides an interface similar to that of iTunes Cover Flow.

HoloMenu is a C library for creating GUIs with holographic simulator view. It helps creating buttons, text boxes and other components with effects similar to Syndicate Wars. It is designed to use as menu in games, but may be used for other projects.

OpenGLEAN: A GLUT family member gone lean.

A GUI library for SDL2 * I've stopped developing this library, at least for now. Please contact me if you are interested in continuing where I left off.

SIGE - Simple Imperative Game Engine SIGE is a toolkit for game creation with OpenGL. At the moment suport for menus, textures, keybindings and configuration files is working. The project plans to include audio and video at a later time.

ShivaVG is an open-source ANSI C implementation of the Khronos' OpenVG specification for hardware-accelerated vector graphics API. It is built entirely on top of OpenGL.
