You can remember the scrollbar position before printing to the widget and restore the position after printing. E.g: 
sub mymain() {
  # This would normally be real text
  my(@old_x_view) = $text->xview;
  $counter++;
  print "this is a very long line we need a scrollbar on the x axis...
+..... this is a very long line we need a scrollbar on the x axis.....
+... this is a very long line we need a scrollbar on the x axis.......
+. well the number is current = " . $counter . " \n";
  $text->xview(moveto => $old_x_view[0]);
}
