FOX is a C++-based toolkit for GUI development. It includes a rich set of widgets and has powerful yet simple layout managers, MDI widgets, and mega-widgets. FOX incorporates support for XDND for drag and drop, X clipboard and X Selection, watching other I/O channels and sockets, timers and idle processing, object serialization and deserialization, a registry to save persistent settings, and 3D widgets using Mesa or OpenGL. FOX works on Linux, IRIX, Solaris, HP/UX, AIX, Tru64 Unix, Windows 9x,NT,2K (VC++, GNUWIN32, Borland, VisualAge C++), FreeBSD, and Sequent.
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.
Faith is a cross-platform C++ graphical application toolkit. It runs natively on Linux/Unix (Xlib) and Windows. It has an API strongly inspired by Qt's and has many features that are expected from a modern toolkit, including a variety of common "widgets", an aesthetically pleasing appearance, and the many critical non-portable components such as anti-aliasing and sockets.
Fl_Editor is a word-wrapping text editor widget for the FLTK toolkit. It supports CUA-style editing keys, automatic scrollbar display, load and save to file or buffer, and more. Fl_Editor includes subclasses with status and position display, find and replace, a couple of utility widgets, a status panel and a progress bar that can be used independent of any of the editors.
The GTK+ Foundation Classes is a set of integrated C++ classes for developing GTK+ applications on Unix-like systems such as Linux. GFC-Core is the core object and utility library that other GFC libraries such as GFC-UI are built on. GFC-Core includes a C++ wrapper for the GLib object system and utility libraries, a standard string compatible UTF-8 string class, automatic memory management, an optimized virtual signal handler system, and a typesafe system of C++ signal and slots.
