Hello All,

Hi!

Suppose a user loaded a command like so: (defun draw-foo (&key (pt1 nil) (pt2 nil))   (unless (or pt1 pt2)     (setf pt1 (prompt-canvas "Define point 1 of FOO."))     (setf pt2 (prompt-canvas "Define point 2 of FOO.")))   (user-defined-drawing-nonsense pt1 pt2))

I think i can see the point (no pun intended), but i wonder if events are the proper way to get user input, then draw with the provided data/functions/shapes. Bye! C.
