Using ET you can invoke a short Tcl/Tk script in the middle of a C routine, or you can invoke a C routine in the middle of a Tcl/Tk script. ET also bundles external Tcl/Tk scripts (including the standard Tcl/Tk startup scripts) into the executable so that the executable can be run on another binary-compatible computer that doesn't have Tcl/Tk installed.

MFC views C++ class for embedding Tk
  The idea of embedding Tk in MFC windows always seemed very enticing but information was sparse and contradictory - on a scale between "very easy" and "not yet possible". The only thing for it was to have a go and lo, it wasn't that hard after all. CTkView is a C++ class which can be used in MFC SDI or MDI applications. An instance of CTkView hosts an embedded Tk toplevel widget and performs some management chores for the widget so that it can size, update and react correctly to Windows events.

The Meta-GUI Tools
  The Meta-GUI tools provide a framework for quickly building full GUI applications. The GUI is rendered by a run-time engine based on a hierarchical set of definitions you provide. At the bottom of the hierarchy are abstract data types such as length, angle, string, etc., and these are used to progressively build up frames, dialogs, toolbars, menus, and operations.

ToGL - a Tk Open GL widget
  Togl is a Tk widget for OpenGL rendering. Togl is based on OGLTK, originally written by Benjamin Bederson at the University of New Mexico (who has since moved to the University of Maryland). Togl adds the new features:

  - support for requesting stencil, accumulation, alpha buffers, etc
  - multiple OpenGL drawing widgets
  - OpenGL extension testing from Tcl
  - simple, portable font support
  - overlay plane support
  Togl allows one to create and manage a special Tk/OpenGL widget with Tcl and render into it with a C program. That is, a typical Togl program will have Tcl code for managing the user interface and a C program for computations and OpenGL rendering. Edit (August 23, 1999 12:14)
