Solution Found!See Bottom of post

After being gently guided (Formatting Gtk Pages) into using Gtk2 instead of Gtk, I have one more question for everyone.

Looking at Gtk2, I quickly hone in on Gtk2::SimpleList as something that could greatly easy my GUI design. It is nearly exactly what I was attempting to do in Gtk. Nice.

I quickly throw together the code to build my SimpleList:

$slist = Gtk2::SimpleList->new (
              'Enabled'    => 'bool',
              'Scanner'    => 'text',
              'Media'      => 'text',
              'Description' => 'text'
            );

@{$slist->{data}} = (
        ['1','test','CDR','Long Description'],
        ['0','test 2','CDR'],
        ['0','test 3','CDR'],
);

And I have my basic interface. Next, I have to setup a callback so that anytime the checkbox in a row changes state something happens. This is where things start to fall apart. I try:

$slist->signal_connect( 'row-activated', sub { printDebugWindow("Click
+ed!") });

But this is only called when the row is double clicked, not when someone simply clicks on the checkbox. I have looked through the signals for SimpleList and I can't seem to find one that I am looking for. I am thinking that since this is just a tied array, there might be some way to access the underlying objects. But, I have not worked much with tied vars and can't seem to figure it out. I tried:

$slist->{data}[0][0]->signal_connect( 'toggled', sub { printDebugWindo
+w("Clicked!") });

But that definately doesn't work. (For some reason I expected it wouldn't since I was pretty much just making up syntax at that point.) Well, I am at a loss at this point. I have read all the documentation that I could find on the Perl-Gtk2 page, the Gtk2 page, and in the pods but I am missing something.

Please, monks, light this path for me.

A solution

Since SimpleList is just an interface to TreeModel, I was able to accomplish what I needed by delving down into the TreeModel itself. 

my $tree_model = $slist->get_model();
$tree_model->signal_connect( row_changed => sub { printDebugWindow("Cl
+icked") });

This works because the SimpleLists in this GUI only have one editible field -- the bool checkbox. So, this signal is only emitted when someone toggles the checkbox. Thanks again for everyone's help, and please let me know if the path I have found is not a good one.
