Hi Takaaki,

Thanks for the pointer and the example.

It isn't my first choice to have an actual screen widget - I'm looking to
construct and pop-up a custom menu from my custom widget's handle method.

Is there a way to have the MenuButton widget created but not actually
mapped on the window?  And then just use menubutton.popup when I want to
show it?

I will tinker some on my own and see what I come up with.

Once only slightly connected question - is there a way to make the arrows
for sub-menus a little more subtle?

Thanks,
Steve
