Install an event filter on qApp (or just the KisView? dunno) and check
whether the widget under the mouse is the canvas, perhaps?
I've already done something like this for amaroK (though that didn't
include mouse movement, only keyboard shortcuts), so if you like and
point me to the code I could give it a shot myself.
