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

I guess you're using Tk.

To add scrollbars, use the Tk::Scrolled. For example, you can create a top scrolled frame:

#!/usr/bin/perl use warnings; use strict; use Tk; my $mw = 'MainWindow'->new; my @array = map join('=', int rand 100), 1 .. 100; my $top = $mw->Scrolled('Frame', -scrollbars => 'e')->pack; my $x = 0; for my $pair (@array) { my ($name, $value) = split /=/, $pair; my $frame = $top->Frame->pack; my $label_index = $frame->Label(-text => $x, -width => 10, -relief => 'groove') ->pack(-side => 'left'); my $label_name = $frame->Label(-text => $name, -width => 30, -relief => 'groove') ->pack(-side => 'left'); my $label_value = $frame->Label(-text => $value, -width => 25, -relief => 'groove') ->pack(-side => 'left'); my $label_description = $frame->Entry(-text =>'description', -width => 30, -relief =>'groove') ->pack(-side=>'left'); ++$x; } MainLoop();

Note that my example is runable as is, while yours isn't (I had to guess the format of the array values, etc.) Also, adding a space here or there improves readability.

The first argument of split is a regex or a space. Also, I prefer single quotes for strings that don't interpolate anything, and no quotes for strings that only interpolate a single variable.

Update: The array is populated wrongly. See Lotus1's reply for a fix.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
