内容説明
Since Tcl and the Tk Toolkit is written by the creator of the Tcl scripting language and the Tk toolkit, this book is the single authoritative resource for anyone who wants to produce far more powerful X Window System applications in a fraction of the time that would otherwise be required. Tcl and the Tk Toolkit offers an introduction and overview of this impressive programming environment, including detailed instructions for script writing in Tcl and working with the Tk toolkit. The book also describes the C interfaces for Tcl and Tk for those readers who wish to extend their built-in features by writing new C commands.
