The problem here, is that you don't have the reference to the actual
TextUndo widget but to the Tk::Frame housing the TextUndo and the scrollbars
(i.e. that is what the "Scrolled" method returns).
To get the reference to the TextUndo widget:
$real_text_undo = $text_undo->Subwidget('scrolled');
Now the following should work:
$real_text_undo->Tk::Text::delete('1.0','end');

PS..I assume you wish to do this because you want to delete something
programmatically but not affect the users undo functionality? I hope not.
Because you "will" affect the undo functionality. You would be deleting
stuff which will likely be in the undo list and then it won't behave as
expected.
