JGraph is a free, mature, and robust Java diagramming library. It contains all the graph visualization, layout, and interaction functionality you might expect in a graph library, including multiple views, layering, zoom, drag and drop, undo, automatic expanding and collapsing, routing, and layouts. You can create workflow editors, BPMN, CAD tools, network diagrams, database visualization tools, and more. It is fully documented, including examples, and has an active support community.
DirectFB is a thin library that provides developers with hardware graphics acceleration, input device handling and abstraction, an integrated windowing system with support for translucent windows and multiple display layers on top of the Linux framebuffer device. It is a complete hardware abstraction layer with software fallbacks for every graphics operation that is not supported by the underlying hardware.
NovaTK is an object-oriented, cross-platform GUI toolkit. One of the focuses of NovaTK is to facilitate rapid development of cross-platform applications requiring fewer lines of code. The event system is based upon a powerful callback mechanism that makes application design simpler, easier to read, and logical.
The CRT X-Y Library (libcrtxy) allows you to write vector-based video games (like Asteroids, Lunar Lander, and Battlezone from the 1970s and 80s). The end-user (and/or packager of your software) determines how lines are rendered, depending on the capabilities of their system. This choice includes anti-aliasing, alpha blending, blurring, and even the display size and depth. Fixed-point math is used, and sine and cosine trigonometric functions (using look-up tables) are provided. The library is based on libSDL and uses SDL as the video backend.
TnFOX is a modern secure, robust, multithreaded, exception aware, internationalizable, portable GUI toolkit library designed for mission-critical work in C++ and Python, forked from the FOX library. It replicates the Qt API in many places, comes with a full set of Python bindings, and has been designed primarily for Tn, the port of Tornado to FOX.
CLIP is a Clipper/XBase compatible compiler with initial support other xBase dialects. It features support for international languages and character sets. It also features OOP, a multiplatform GUI based on GTK/GTKextra, all SIX/Comix features (including hypertext indexing), SQL and ODBC drivers, a C-API for third-party developers, a few wrappers for popular libraries (such as BZIP, GZIP, GD, Crypto, and Fcgi), a multitasking client and application server based on TCP/IP sockets, object data base utilities, and a functions library.
flmkisofs is a very simple program for creating ISO images with the mkisofs program. It can create DVD video ISO images, Apple ISO filesystems, HFS/ISO filesystems, and El Torito or Generic bootable ISO filesystems. It fully supports versions 1 through 3 of the ISO filesystem standard, with RockRidge and Joliet extensions, and has partial UDF support.
