Mastering Perl/Tk

Chapter 13. Miscellaneous Perl/Tk Methods

So far, most of the chapters in this book have concentrated on specific widgets. This chapter covers the methods and subroutines that can be invoked from any widget. You’ll probably never need most of these methods, but there are a few that you’ll use frequently, particularly configure and cget.

Most of the methods are based on the Tcl winfo command (window information). Generally, the commands are informational only, meaning you pass no arguments to them; you only get a value back.

This chapter also documents clipboard and selection methods for cut-and-paste operations between applications, focus and grab methods, and a few esoteric goodies.
