Description

 

The Tcl scripting language and the Tk toolkit together create a programming environment for creating graphical user interfaces. There is increasing interest in using Tcl/Tk in university classes in order to free students to concentrate on algorithms, etc., rather than spending lots of time on implementation in a lower level language. Anyone who has read Ousterhout's definitive description of the language and wants to learn more about Tcl/Tk will find this book the perfect next step. Based on the authors' extensive experience building and deploying mission-critical Tcl software and teaching others to do the same, this book offers a wealth of practical information on how to exploit the full potential of this remarkable programming environment. Using real programs as examples, the book demonstrates Tcl and Tk concepts. It shows readers how to build Tcl applications effectively and efficiently through plenty of real-world advice, offers valuable design strategies, and points out pitfalls that readers should avoid. It clarifies the more confusing aspects of Tcl/Tk and thoroughly explains Tcl features that have no counterpart in conventional programming languages. Preface.
