Builder Xcessory PRO for Linux is the industry's most advanced graphical user interface builder for Motif. BX PRO provides a comprehensive visual reuse environment that speeds development of mission-critical applications. BX PRO integrates three best-of-breed tools to create an unparalleled application development suite.
BX/XIK automates the integration of Sitraka's (formerly KL Group) Motif based XRT widgets into Builder Xcessory PRO. After installing the XRT Integration Kit, the XRT widgets will appear on the BX PRO palette and can be "dragged-and-dropped" to create a sophisticated Motif-based user interface.
DiaCanvas is a generalized version of the drawing canvas used by DIA. It extends some features used by DIA and adds new ones, while preserving as many of the original features as possible. This project is no longer actively maintained. It is suggested that you try DiaCanvas2 instead.
DLDialog offers the capability to draw a variety of widgets, in order to ease the human user in feeding input to the script. The program is designed to be particularly useful to implement system administration scripts. It includes a definition language similar to Tcl/Tk. It can display dialogs (with the same definition) using characters with the tvision/ncurses interface or using graphical windows with the QT/X11 interface.
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.
gtkmm (previously known as Gtk--) is a C++ interface for the popular GUI library GTK+. It provides a convenient interface for C++ programmers to create graphical user interfaces with GTK+'s framework. Highlights include typesafe callbacks, widgets which are extensible by inheritance, and many classes that can be easily combined to quickly create complex user interfaces.
GtkCanvas is a straight port of the GNOME Canvas from the stable gnome-libs 1.2.4 back to gtk+. This widget behaves identically to the GnomeCanvas widget, with the same APIs, except the names are changed from gnome_canvas to gtk_canvas. Since the next version of gtk+ will drop GdkImLib and intgrate with gdk-pixbuf, it is expected that future versions of this widget will depend upon gtk+ only. It is intended that GtkCanvas will follow GnomeCanvas closely, merging new code whenever a stable release of the latter is made. Thus this is not really a fork but rather a "re-packaging" of the same code.
