This change to the code creating the Tk::HList widget will cause a changing, pipe ('|') separated, list of paths to appear in the Tk::Label as you move the mouse and highlight different parts of the tree.

my $hlist; $hlist = $app_F->HList( -itemtype => 'text', -selectmode => 'extended', -browsecmd => sub { $label_text = join '|' => $hlist->selectionGet + }, );

The (possibly) odd-looking "my $hlist; $hlist = ..." is intended: $hlist is used in the -browsecmd callback, so it needs to be declared before the widget is created and assigned to that variable. There's no syntactical reason for putting the separate declaration and assignment on the same line: use whatever style suits you.

As before, process the array returned by $hlist->selectionGet however you want. Also, see the Tk::HList documentation for how this behaves differently in scalar context.
