A practical guide focusing exclusively on Web applications of Tcl/Tk Like Java, Tcl/Tk enables programmers to create programs that can run independent of graphical hardware or operating systems. This makes it a natural for Web developers. Packed with real-world examples, this book reveals how to write a complete browser in the latest version of Tcl, create GUI components, and use Tcl to interact with Java, JavaScript, and CGI/Perl. It also demonstrates how to write Tcl applets, called "Tclets" and provides plug-ins that can handle these applets. Tcl (Tool Command Language) is a scripting language with its own built-in interpreter that can be used to easily develop applications. Tk is the Tcl toolkit for building graphical interfaces. Companion Web site features all code and Tcl applets from the book.
