Exercises, examples and other material relating to training module T250. This module is presented on Private Courses and Specially Run Courses only
BackgroundSnit is a pure Tcl object and megawidget system. It's unique among Tcl object systems in that it's based not on inheritance but on delegation. In this module we examine what that means in pracise, and how we can make full use of the flexibiity and addiitonal powers provided by snit as we build suites of applications.
Some modules are available for download as a sample of our material or under an Open Training Notes License for free download from [here].
