Hello,
I would like to write a program on the Mac which at the start only
shows the menubar: only after the user has selected an option from the
menu would the first window appear.

However I can't get that to work in Tk. It seems that a Tk GUI can't do
without a TkRoot widget and TkRoot is shown as a window.

Is there any way to make the TkRoot be the menubar itself? Or maybe to
make TkRoot invisible? Or any other solution to achieve the same goal?

Thank you.
