bind hover on tkinter.ttk.Treeview

[Larz60+]

I have been trying to find an example that shows how to bind mouse over Treeview cell without much success.
I thought that '<Enter>' could be used, but that is on the widget level, not the cell level
Perhaps I am not working my search correctly, but I can't find a single example or discussion on the subject
I can't remember all that I have tried, but the one I thought would work was 'hover + tkinter.ttk.Treeview'

This looked promising (and still may be), but the entry for Treeview, has no mention of active color. However,
there is mention in spinbox, and other widgets, and I haven't tried that, so I will do that next.

In the mean time, if anyone has an example, I'd love to see it.

Thanks Larry
