perlNoob has asked for the wisdom of the Perl Monks concerning the following question:

Hello,
I want to make a Tree made up of checkboxes (so the user can chose (one or more) specific nodes of the tree) and it has confused me quite a bit.

Should I still use Tk::Tree?
Could anyone please point me out to the right direction because I'm a little lost

again, much appreciated

    You'll probably have to write your own mega-widget for this, but something generic like Tk::HList might be a good starting point.

      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)

    Do let us know what you come up with... I can see that being a useful tool :-)

    (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!)

    As long as I never saw such widget before (closest I saw is list list of checkboxes) I doubt there exists any.
    Probably no-one bothered creating such.

    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...

    though it contains no checkboxes you should perhaps have a view on dstat for some inspiration regarding Tk::HList.

    Hi, Here is the solution (actually very simple, but one have to know that). 
    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();

MainLoop;

    thanks a lot for the information, I don't know if I would be capable to crack this on my own
    I would at least need a starting hand, but I think I'm just going to try the list of checkboxes for now

    if I do try to do it and manage it I will let you know.
