Also read "perldoc Tk::Derived" for more info on making your own module, you can google for some info on it too. If you want to get fancier with your module, like pass in custom options, use cget, or configure on it, you may be smart to use Tk::Derived. shmem's example uses "base", but you can add Tk::Derived with little effort, as shown in the perldoc.
