Are Tkinter StringVar (IntVar, FloatVar, etc) thread safe, eg.
can a background thread read or write to these objects? Or must I
use a Queue to pass information between my background thread and
my main Tkinter GUI thread and have my main Tkinter thread pop
the Queue and update the application's StringVar's accordingly?

I know my background threads can not read or write a Tkinter
widget directly but I'm unclear on whether StringVar's are
considered widgets or if they are objects far enough removed from
widgets that they are thread safe.

Thank you,
Malcolm
