Tk: Temporarily change cursor?

[Greg McFarlane]

As far as I am aware, there is no (easy, reliable) way to do what you
want (create a busy cursor) using Tk.  The Blt extension to Tk
provides the "busy" Tcl command to do this.  You will need to install
Blt and then you can access this from python.  Pmw provides a python
interface to the Blt busy command.
