Unfortunately, HList is not generic enough to take widget as values (or more precisely its nodes), otherwise this would be trivial.

Sorry, you're wrong. Using itemType 'window' you can pass it any widget you like. (I know, because I'm doing it with Entries, Checkbuttons and BrowseEntries)

(If you want someone to bang on it with you, let me know. I've been monkeying with Tk for a bit - not an expert by any stretch - but willing to hack!)

But it seems to me using namely Tk::Tree this is quite possible: display items could be any window, however they must be different windows (not instances of same window)

Did not tried this myself though...

use Tk;
use Tk::Tree;
use strict;


my $Main = MainWindow->new;
    $Main->title("kuku");

my @win;
my $kuku;
my $info_m = $Main->Frame(-relief=>'groove',-borderwidth=>'3',)->pack(
+-side => 'left', -expand => 1, -fill => 'both',);
        my $tree = $info_m->Scrolled("Tree")->pack(-side=>'top',-expan
+d=>1,-fill=>'both');
        #my $win = $Main->Toplevel;
        $win[0] = $tree -> Checkbutton(-text => "Kaka", -variable => \
+$kuku);
        $win[1] = $tree -> Checkbutton(-text => "Kaka2");
        $win[2] = $tree -> Checkbutton(-text => "Kaka2");
        $win[3] = $tree -> Checkbutton(-text => "Kaka2", -variable => 
+\$kuku);
        $tree -> add("one", -widget=> $win[0], -itemtype => 'window');
        $tree -> add("one.two", -widget=> $win[1], -itemtype => 'windo
+w');
        $tree -> add("one.two.muku", -widget=> $win[2], -itemtype => '
+window');
        $tree -> add("three", -widget=> $win[3], -itemtype => 'window'
+);
        $tree -> add("four",-text=> "four");
        
        $tree -> autosetmode();
