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

Am working on something in Perl/Tk. DirTree has a -command=>\&foo feature. I need something like that for Listbox, so that I can update something else when a line in the Listbox gets selected. How might I do that, please?

    I think you want something like- 

    $listbox->bind('<ButtonRelease-1>', [ sub { do_something() } ]);

    The Tk::Listbox doesnt appear to support this feature. So you have a choice of: Extending it yourself to add it, or: using Tk::TList, which appears to be able to do that (and can probably look like a Listbox, if it wants to..)

      Yes, thank you. TList is just the ticket.
