[...deriving from one of the widget class... this is a common practice, no?
So, you're probably safe anyway...]

Definitely.

Sorry -- I missed the very beginning of the thread.  Indeed a public
Tkinter.root() (or .default_root()) seems like the best solution.

For the short run you could duplicate _root() in your own code -- it
relies only on "public" members after all ;-)

Class Misc:
...
	def _root(self):
		w = self
		while w.master: w = w.master
		return w
