Many of the Tcl and Tk applications and libraries fall in to one of several different "families". Some are filters. Others are simple single-dialog GUIs. Wouldn't it be nice to have a collection of application templates which include some of the "basic stuff" that you end up re-writing into each new application? It turns out that this good idea is supported by ActiveState
Here are a series of code templates that can be useful as you create your applications. Feel free to add your own.
