ROText

This is a Text widget with all bindings removed that would

alter the contents of the text widget. Text can be inserted pro-

grammatically but not altered by the user.

Scrolled

Perl/Tk includes the special constructor Scrolled which cre-

ates a widget with attached scrollbars, as long as the widget

class supports the x/y scrollcommand(s), as Canvas, Entry,

Listbox, and Text do. Scrollbars can be required, or might

spring into existence only when needed.

$scrolled = $parent->Scrolled(widgetClass ...);

You may specifiy option/value pairs which are passed to the

widgetClass constructor.

-scrollbars => scrollbarSpecs

The strings

n, s, e, and w specifiy top, bottom, left, or

right scrollbars, respectively. The string sw creates two

scrollbars on the left and bottom of the widget. The string

o means optional and r required, so rwos means required

on west (vertical), optional on south (horizontal).
