in reply to How to scroll MainWindow , consists of many frames

As a side note, the lexicals  $label_index $label_name $label_value $label_description are scoped entirely within the for-loop of the OPed code and any values assigned to them vanish at the end of that loop. I assume you're saving these values into some structure in an enclosing scope, but if you're not, you can save your eyesight and fingertips by getting rid of them.

Also, your use of  @var and  $x in the (pseudo?) code suggests you're not using strict and warnings. If that's actually the case and not just an artifact of the example, use strict and warnings. :) The runnable example code of choroba and Lotus1 handle these variables "correctly" IMHO.

Give a man a fish:  <%-{-{-{-<
