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

I have a working menubar configured via the "slick, new-fashioned way" from the book Mastering Perl/Tk.

It works, but I need to know that menubar's height. And I can't seem to figure what it is that I call...

?->reqheight

...on? Or how else do I do it?

I've been trough the book and nothing stands out. How might I determine the height if my menubar, please? Don't need the height of any cascaded items, just the always-visilbe bar itself.
