The Fast Light Tool Kit (FLTK) binding for Tcl/Tk is a dynamic extension to the Tcl/Tk application development environment that implements a GUI development environment based on the FLTK library. This Tk look-alike has a rich widget set that can be used for the rapid development of GUI appliactions. The extension is available for both RH Linux and MS Windows in the form of binary distribution, and is also available as a source distribution. The Tcl FLTK extension allows for the development of GUI applications using Tcl commands in a manner similar to the Tk extension, but is considerably more economical in terms of code size. FLTK applications use a native interface to their host platforms, and consequently are typically faster than equivalent Tk application.
The FLTK library distribution is available from http://www.fltk.org . Users of the binary release of the FLTK extension for Tcl/Tk do not need to install the FLTK libraries as the extension is statically linked with the library.
The FLTK extension for Tcl/Tk comes with extensive documentation on how to use it to develop GUI applications. Example code in the distribution contains several useful scripts for things like the display of weather information and image animation. The current release of the extension is available at http://pages.infinit.net/cclients/software.htm
Some technical notes based on other work that I have done:
Quite a few extensions that I have written for Tcl/Tk for my own use are available from my home page at: http://pages.infinit.net/cclients/software.htm
What: Grab
Description: General purpose window capture functionality for use with Tcl scripts under Windows, provided as a console command version. Currently at version 1.0.
What: Image

Does NOT use Tk and does no visualization. Currently at version 1.1.
What: Variety of Windows extensions (Findleton)
Description: Currently available are extensions that support DDE (v 203), Winhelp 2.0), printing (tkprint 1.1.6), frame animation, BMP creation, and an extension that does "everything" that DDEML does, including being able to write DDEML servers entirely in Tcl.
What: Containers
Description: Small Tcl extension that implements basic container objects, such as bag, queue, tree, priority queue, random queue, struct, stack, hash, FIFO, LIFO, etc. Code is in C++, using templates.
