FXPy is a Python extension module which provides an interface to the FOX cross-platform GUI library. With a few minor exceptions, FXPy provides a complete interface to FOX. FOX is a C++-based toolkit for developing graphical user interfaces easily and effectively, and it runs natively under both Unix/X and Microsoft Windows. Some of the significant features of FOX include a rich set of widgets, powerful but easy-to-use layout managers, extensive support for 3-D modeling using OpenGL or Mesa, drag-and-drop (using the XDND protocol) and a registry for persistent application settings.
g2 is an easy to use, portable and powerful 2D graphics library. It provides a comprehensive set of functions for simultaneous generation of graphical output on different types of devices. The following devices are currently supported: Postscript, X11, FIG (xfig), PNG, and JPEG using the gd library, and Win32. g2 is written in C (ANSI) and additionally has Fortran, Perl, and Python interfaces.
GCache is a Python module that provides a generic cache class useful for speeding up any application where objects are referenced by keys. It uses object metadata to optimize hit-rates and freshness for fetches, and uses a "write-through" mechanism for writes and deletes. It can use "if-modified-since" fetches or rsync delta updates to refresh stale cached objects. GSource classes are provided for generating useful metadata from common sources (os.stat calls and MIME headers). A simple example urlCache is implemented that supports HTTP 1.1 (rfc2616) cache-control and expire headers to ensure freshness. Also included is an rfc2616 package useful for parsing HTTP 1.1 headers, and a PCache package implementing a persistant cache using a Python shelve.
GDAM is real-time digital dj mixing software package. Any number of mp3 files can be played and mixed simultaneously. Effects can be added, changed, and rearranged dynamically. GDAM features a client-server architecture; all sound is produced by a server, which receives instructions from any number of clients. Other features include plugins for audio effects and interface components, cacheing and looping, sequencing, assisted beatmatching, a waveform viewer/beat calculator, contiguous queueing (no pauses between songs when using a playlist), an online help system, an mpg123 clone which runs on a gdam server, flexible command line interface for direct control of server, recording of entire mix or any point in stream to buffer/disk/mp3 encoder, support for multiple sound devices, and support for midi hardware control.
GdkRgb is a rewrite of the image rendering subsystem of Gtk+. Advantages over plain Gtk+ 1.0.x include higher speed, very smooth and pretty dithered modes, and support for more displays and visuals. It is currently checked into development versions of Gtk+ (and used in the development tree of the Gimp), but is also packaged separately for application authors who want to maintain Gtk 1.0.x compatibility. The programming interface is quite simple.
genroms is a utility meant to aid in generating ROM files for arcade machines or emulators. You pass it in a standard Intel Hex File (.IHX) along with a description of the ROM layout in memory (.ROMS), and it will generate the ROM files as specified in the ROM layout file. It is primarily meant to help people that are trying to write programs for arcade machines, or for circumstances where the ROM layout may be strange or non-contiguous.
