Ttk is the new Tk themed widget set, \
and one widget that is available in themed form is the menubutton. \
Below are some themed menu buttons \
that allow you to pick the current theme in use. \
Notice how picking a theme changes the way \
that the menu buttons themselves look, \
and that the central menu button is styled differently \
(in a way that is normally suitable for toolbars). \
However, there are no themed menus; the standard Tk menus were judged \
to have a sufficiently good look-and-feel on all platforms, \
especially as they are implemented as native controls in many places.
