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.
