in reply to Scrolling data in Tk

It appears to be from your use of place, rather than pack or grid, to position the buttons and labels within the scrolled frame. I guess, by you taking control of the placement geometry, the scrolled geometry manager doesn't have enough information to know when to enable the scrollbars.

    Ouch. A quick experiment with pack gets the scrollbar working, as you promised. The output looks ghastly, but that's because it was a quick experiment & I don't grok pack. I was scared of this sort of ambush when I asked about it in Tk: pack, grid or place?, but the closest anyone came was g0n's warning about resizing.

    Thank you for this - off to the manuals!

      In this case it's probably much easier to convert to grid, rather than, pack, since you're already in effect faking your own grid layout. 

        for (@data) {
    $chkReport[$i] = $frame
        ->Checkbutton()
        ->grid( -column => 0, -row => $i ); #==
    $lblReport[$i] = $frame
        ->Label( -text => $_ )
        ->grid( -column => 1, -row => $i ); #==
    $i++;
  }
