What is Vtcl?
Visual Tcl is a freely-available, high-quality application development environment for UNIX, Windows, Macintosh and AS400 platforms, says Stewart Allen, its developer. With vTcl you can design not only the graphical view of your application, using visual tools and “What You See Is What You Get”, but also write and test the Tcl procedures and TK events bindings that drive it. You even have a “Test” button hat runs your application from within vTcl. When you are satisfied, you just save your work and it is ready to run. The saved work contains no vTcl specific code, and if you find the need to edit it outside vTcl, you can do it and yet read it gain in vTcl. If you have already a running application using pure Tcl/Tk code you can read it from within vTcl and continue developing it.
