Tkinter - mouse cursor position

[James Hall]

Help,

Is there a way of setting the mouse cursor position in a Tkinter canvas 
(other than by moving the mouse that is).

Suppose a canvas showing some form of visualisation, clicking on a 
feature of interest causes the visualisation to be redrawn in such a way 
as to move the feature - the mouse cursor should then appear in the new 
position, still over the feature. Calculating where it should be is 
trivial, but search as I may I cannot find out how to move the cursor to 
the new position as required. Can't believe that this simple 
functionality is missing.

Any suggestions gratefully received.
