内容説明

With Tk, Perl programs can be window-based rather than command-line based, with buttons, entry fields, listboxes, menus, and scrollbars. Originally developed for the Tel language, the Perl port of the Tk toolkit liberates Perl programmers from the world of command-line options, STDIN, and STDOUT, allowing them to build graphical, event-driven applications for both Windows and UNIX. This book is aimed at Perl novices and experts alike. It explains the reasoning behind event driven applications and drills in guidelines on how to best design graphical applications. It teaches how to implement and configure each of the Perl/Tk graphical elements step-by-step. Special attention is given to the geometry managers, which are needed to position each button, menu, label and listbox in the window frame.
