Re: Scrolling data in Tk

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++;
  }
