Thanks for the help Ken and Christopher! Attached is an example file of
what I've got running now. It should run on its own. A wx tooltip pops
up whenever the mouse is over the axes. The tooltip's hangs obediently
off of the bottom right of the mouse cursor. Its string is updated to
reflect the current position of the mouse in data coordinates.
I'll make a post to the devel list, maybe get this added to the MPL
examples.
Cheers,
Martin
