    Agar

    Agar

    Cross Platform GUI Toolkit

    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.

    libthreadar

    C++ library to manage threads and any type of exception between them

    Libthreadar is a C++ library providing an abstracted set of C++ *classes* to manipulate threads in a very simple and efficient way from your C++ code. It also handles exceptions thrown from a thread and propagated to another one, when the later is calling the thread::join() method. This let one manage exceptions as simply as it is in C++ single threaded context. Additionally, all the related objects around multi-threading (mutex, semaphore, ...) are provided, under easy to use and independent C++ classes. Other more advanced classes ease the information exchange between threads like scattering and gathering a collection of objects between many threads, or asynchonous buffered information exchanges between two threads. All these C++ classes are easy to use and fully documented
