Chapter 8. The Text, TextUndo,and ROText Widgets
The Text widget is one of the most powerful standard widgets available in Perl/Tk. It is flexible, configurable, and easy to use for simple tasks. You can use Text widgets to:
Display and edit a plain text file
Display formatted text from an HTML document
Create a scrollable color key, with Buttons that allow you change the colors
Gather multiline, formatted text (including colors) from a user (act as a mini word processor)
Display text with different colors based on the input
Create hypertext windows that perform actions when clicked (either HTML or similar to the widget demo).[1]
You can put text as well as other widgets inside a Text widget. A Text widget can be used in conjunction with Scrollbars to allow many pages of information to be viewed in much less space.
[1] When you installed the Tk module with Perl, you also installed
the widget demo. Type
widget on the command line to see the
capabilities of widgets in Perl/Tk.
