Scrolled frame within a window

I have been trying to get a window that has a frame that is scrolled and a
frame that is not scrolled.  Using the very helpful post archived at
http://www.nntp.perl.org/group/perl.tcltk/2010/03/msg393.html, I think I
have gotten very close to what I want.  The problem I still have is that
the widgets in the frame with the scrollbar do not move when I move the
scrollbar.  I'm certain I'm missing something simple but I don't see what.

If anyone can suggest what silly little piece I have missed, I would be
grateful.  Here is the code I am using:

use Tkx;
Tkx::package_require("BWidget");

$rows = 10;
$columns = 20;

$mw = Tkx::widget->new(".");
$mw->g_grid_columnconfigure(0, -weight => 1);
$mw->g_grid_rowconfigure(0, -weight => 1);

  $mwf1 = $mw->new_ttk__frame();
  $mwf1->g_grid(-column => 0, -row => 0, -sticky => 'ew');
  $mwf1->g_grid_columnconfigure(0, -weight => 1);
  $mwf1->g_grid_rowconfigure(0, -weight => 1);
    $button = $mwf1->new_ttk__button(-text => 'button');
    $button->g_grid(-column => 0, -row => 0);

  $mwf2 = $mw->new_ttk__frame();
  $mwf2->g_grid(-column => 0, -row => 1, -sticky => 'ew');
  $mwf2->g_grid_columnconfigure(0, -weight => 1);
  $mwf2->g_grid_rowconfigure(0, -weight => 1);

    $mwsw = $mwf2->new_ScrolledWindow(-managed => 0);
      $mwswf1 = $mwsw->new_ScrollableFrame();
    $mwsw->setwidget($mwswf1);
    $mwsw->g_grid(-column => 0, -row => 0, -sticky => 'ew');

    $mwsw->g_grid_columnconfigure($mwswf1, -weight => 1);
    $mwsw->g_grid_rowconfigure($mwswf1, -weight => 1);

  $f = Tkx::widget->new($mwswf1->getframe());
  $f->g_grid(-column => 0, -row => 0, -sticky => 'ew');

for $i (0 .. ($rows - 1)) {
  for $j (0 .. ($columns - 1)) {
    $cell[$i][$j] = $f->new_ttk__entry(-width => 10);
    $cell[$i][$j]->g_grid(-column => $j, -row => $i, -padx => 0, -pady =>
0, -sticky => 'nsew');
    $cell[$i][$j]->insert(0, "$i, $j");
  }
}


Tkx::update('idletasks');
Tkx::wm_geometry($mw, "600x" . Tkx::winfo_reqheight($mw));

Thanks,
Scott
