Perl/Tk Pocket Reference

Introduction

Perl/Tk is the extension to Perl for creating graphical user

interfaces. This small book presents every Perl/Tk graphical

element, including general widget and variable information,

callbacks, geometry management, bindings, events, window

management, as well as composite widget, font, and image

creation and manipulation commands, all of which are

described in detail in O’Reilly & Associates’ Learning Perl/Tk.

I am very grateful to Achim Bohnet, who tenaciously

reviewed this work as it evolved.

Conventions

1. General Perl/Tk

Widget Information

All Perl/Tk programs must have a use Tk statement. To use

special Perl/Tk widgets like Dialog a use Tk::Dialog statement

is required.

All widgets are created with:

$widget = $parent ->widgetClass (?-option => value, ...?);

fixed

denotes text that you enter literally

italics means variable text, i.e., things you must fill in

bold is a keyword, i.e., a word with a special meaning

?... ? denotes an optional part
