A general method on all widgets; w.winfo_pointerxy()
Returns a tuple (x, y) containing the coordinates of the mouse
pointer relative to w's root window.
If the mouse pointer isn't on the same screen, returns (-1, -1).
Use this method on you canvas.
If you canvas is scrolled, then you need to adjust these coordinates
(since the top-left corner of the visible canvas may not be (0,0) of
the canvas coordinates)
So do something like:
Note also you can bind methods to events
(not only clicks on your canas, but also movement)
When the method is called, it gets an event object as one
parameter, and this event object includes the x and y of the cursor
I am workin from memory here, so don't tak my word for it.
