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. Diego Virasoro
