Use the delete method. For example: 
$txtWidget = $Window->Scrolled("Text");
$txtWidget->insert('end',"blah blah blah blah");
$txtWidget->delete('0.0','end');

This will delete all the text in your text box. If you'd like to delete just a section of it, you'll want to specify a start and end index.

This and other Tk methods are documented in the Tk perldocs.

Update: In my haste, I made a mistake. It has been corrected above. $txtWidget->delete(0,'end') should be $txtWidget->delete('0.0','end').
