Does anyone know how i clear data from a txt scrollbox.

code is

$mainmenu = new MainWindow;
my $mbar = $mainmenu -> Menu();
$mainmenu -> configure(-menu => $mbar);
#Making a text area
my $txt = $mainmenu -> Scrolled('Text',-width => 50,-
scrollbars=>'e') -> pack ();


So when i want to clear all of the txt in that box that
other routines might have put in there is there something like
$txt->clearbox;
